Imagine an unsuspecting bunch of Armoured<br />

Corps personnel, engrossed in live firing at a<br />

range in the North West sector. Tanks and APCs<br />

milling around, kicking up a lot of dust and the RSO<br />

trying his best to peer through the obscurities, to<br />

keep track of results of firing. It was quite akin to<br />

a real battle scenario and the prevailing visibility<br />

over the range did not make matters any easier<br />

for any one. They had a task at hand and were<br />

doing their best to get the maximum out of the<br />

exercise underway. Little did they know that an<br />

unpleasant surprise was already beginning to<br />

unfold and that their exercise was about to turn a<br />

lot more realistic.<br />

orbiting endlessly in an attempt to pick up the<br />

targets. The local SU had tried its best to guide<br />

the hapless pilot but to no avail. Finally, good<br />

sense prevailed and he decided to call off the<br />

mission. The RSO too heaved a sigh of relief and<br />

was happy to hear the pilot change over to the<br />

SU channel for the trip back to base.<br />

Since the range had not been sighted, the<br />

return navigation too started off on an uncertain<br />

footing. Probably the pilot put all his trust in his<br />

on-board systems and hoped that eventually the<br />

SU would pick him up and help him get back<br />

home. Nothing wrong with that, but it certainly<br />

Some distance to the West, a lone MiG-27<br />

was involved in heavy armament work over the<br />

Air Force portion of the firing range, with 2 x 500<br />

Kg bombs. Though a simple enough exercise,<br />

things did not seem to be going well that day.<br />

The problem was understandable and had been<br />

experienced by many pilots in the past. The<br />

problem was that the pilot was not able to make<br />

contact with the range or any familiar feature in<br />

its close vicinity. In such sorties, fuel is always at<br />

a premium so one does not enjoy the luxury of<br />

would have been wiser to confess that one was<br />

heading back and was somewhat unsure of his<br />

ground position. Time ticked away. The RSO in<br />

the meantime prepared to close the range and<br />

call it a day which had been quite uneventful till<br />

the small aberration, a little while ago. All of a<br />

sudden the aircraft that had just left range, piped<br />

up on R/T announcing that he now had the<br />

target in contact and was seeking permission<br />

to go in for ‘direct live’. Fuel considerations<br />

seemed to have weighed on the RSO’s mind as<br />

well and he decided to clear the pilot for direct<br />

live, without the mandatory Safety Height Run<br />

first. Also, he did not establish visual contact with<br />

the aircraft anywhere on the circuit. This should<br />

have woken him up but events that had been set<br />

in motion probably were too fast for him to evoke<br />

a rational action. Even when the pilot called out<br />

that he was now rolling in live, the RSO did not<br />

react. A confident call, “You are clear live”, was<br />

ground. I, as the Flight Commander of the unit<br />

got an unwelcome call from the COO and he<br />

wanted to know whether any of our aircraft<br />

was still operating over the range. His very tone<br />

suggested that something was drastically wrong<br />

and soon the AOC and the COO descended<br />

on the dett. To everyone’s horror, it was quite<br />

obvious that a fighter had just dropped two<br />

live bombs bang in the middle of the army<br />

all that he transmitted. The next call from the<br />

pilot announced, “Bombs Gone, Switches Safe,<br />

returning to base”. But even after a minute, the<br />

RSO had not spotted any bomb impact on the Live<br />

Bombing Target (LBT) or anywhere in the range<br />

area. The natural thing then was to put down the<br />

binoculars and call up the pilot to cross check<br />

if bombs had indeed been released. On being<br />

confirmed in the positive, the RSO responded<br />

by transmitting, “Bombs not sighted, probably<br />

gross undershoot. You are clear to change<br />

over to the SU”. The range was closed thereafter<br />

and the pilot navigated safely back to his base,<br />

basking in the belief that the mission had finally<br />

been accomplished. The mission in fact had gone<br />

wrong completely.<br />

Things seemed to have settled down to<br />

routine for the pilot but all was not well on the<br />

ranges and naturally, the guys in the OG were<br />

furious. Fortunately, no one was hurt and there<br />

was no damage to any vehicle or structure. The<br />

next dignitary to arrive in the unit was the Air I<br />

from the Command Headquarters and I was<br />

told to get busy writing an Executive Report on<br />

the pilot. His fighter flying days were over,<br />

all because of one avoidable mistake that he<br />

failed to correct on time.<br />

It would be worth pondering over the<br />

following :<br />

The location of this particular range<br />

is such that many times picking up targets is<br />

difficult. The navigation to the range therefore<br />

has to be taken very seriously. In fact, the<br />

navigation to any destination has to be taken<br />

very seriously. Odd instances of inaccuracies<br />

creeping in are understandable... but think...was<br />

there an excuse for the pilot not being able to<br />

find the range in broad daylight<br />

Fuel considerations notwithstanding,<br />

permission to go in for direct live for aircraft<br />

operating alone, must be granted only under<br />

exceptional and pre-briefed circumstances. What<br />

such exceptional circumstance are, need to be<br />

spelt out unambiguously and briefed properly.<br />

Since the LBT at this range or for that<br />

matter at any other heavy armament range would<br />

generally be obscured because of weapons used<br />

earlier, be aware of the other features on and<br />

around the range to help you identify the targets<br />

correctly.<br />

Once the decision to abort the mission<br />

had been taken, suddenly reverting and seeking<br />

permission for direct live was certainly not in<br />

order. The pilot was probably not comfortable<br />

with the idea of landing with two bombs under<br />

slung. Operating manuals do permit landing<br />

under such configuration, but don’t you think all<br />

operators should be aware of this<br />

Should the RSO have cleared the pilot<br />

for a direct live attack without the Safety Height<br />

Run Again a matter of practice but the pitfalls of<br />

doing so must be understood.<br />

Now for a dive bomb attack, there is no<br />

way that an aircraft in dive will not be visible to<br />

the RSO. Surely, if the visibility is that bad, won’t<br />

the better option be to close the range<br />

Having cornered the RSO into clearing<br />

him for a direct live attack, how about the pilot<br />

confirming with other features around, what he<br />

believed to be the LBT and that he indeed was<br />

going in for the correct target.<br />

During the entire episode, the RSO did not<br />

spot the aircraft. Worse still, he did not even hear<br />

it. Should this have forced him to do something<br />

other than what he eventually did<br />

The RSO did not intervene even when the<br />

aircraft confirmed rolling in live and he was yet<br />

to establish visual contact. He simply assumed<br />

that the pilot eventually had things under control<br />

and was going in for the correct target. The pilot<br />

too assumed the same and pressed on with<br />

the attack. Remember the old adage, ‘DO NOT<br />

ASSUME. It makes an ASS out of U and ME’. In<br />

this case, it certainly did and consequences could<br />

have been worse.<br />

Getting ‘Bombs Away’ is the sole desired<br />

culmination in such a live firing mission but<br />

please be sure, the bombs are aimed at the<br />

desired target and nowhere else. Live bombs<br />

are dangerous instruments with considerable<br />

destructive power. Therefore there can be no<br />

complacency in the manner they are released.<br />

When in doubt ... DO NOT PRESS THE TRIGGER.<br />

A large number of seemingly weird<br />

incidents happen at firing ranges everywhere.<br />

Some result in very unpleasant consequences for<br />

players involved and many times even for those<br />

who are caught unaware on the ground, for no<br />

fault of theirs. Sharing your experiences with the<br />

environment can certainly increase awareness<br />

and minimise chances of recurrence of such<br />

avoidable incidents. If you are in agreement with<br />

this, then please do get in touch with the ‘editor’<br />

with your story without any delay as it is quite<br />

likely that someone else could enact something<br />

close to what you did and you could help him<br />

avert the same !<br />

Editor’s Comments :<br />

Inability to spot the range is a situation that<br />

many aircrew would have experienced.<br />

However, the lesson for all is to avoid the<br />

compulsion to believe that everything is<br />

fine, when it actually isn’t. Every<br />

tale may not have a happy<br />

ending!<br />

Mental health is an important aspect of<br />

total positive health. Every physical<br />

ailment has a mental component and<br />

every mental illness has a physical component.<br />

The WHO Expert Committee defines mental<br />

health as ‘the capacity of an individual to<br />

establish harmonious relations with others and<br />

to participate in or contribute constructively to<br />

change in the social environment’.<br />

Stress<br />

There is a lot of talk going around these days<br />

about stress. Almost every week, some medical<br />

journal or lay magazine brings out an article<br />

on this issue. Most of the<br />

time, doctors also tell their<br />

patients to cut down on<br />

their stress. However, to<br />

the general public and<br />

patients, it is quite vague and<br />

confusing. What is stress Why does it occur Can<br />

we do away with it Such questions can be quite<br />

intriguing.<br />

Stress Response<br />

It is actually not the stress that concerns us;<br />

what really concerns us is the “Stress Response”.<br />

This is the sum total of body reaction, both<br />

physiological and psychological, in response to a<br />

“stressor”. So, it is not really the “Stressor” (i.e. the<br />

situation) that leads to stress but our perception<br />

of that event, the meaning we attach to it and<br />

the way we react or respond to it, that leads to<br />

symptoms or diseases of stress.<br />

Stimuli from the environment or thoughts<br />

generated within the mind become amicable or<br />

inimical depending on whether they generate<br />

positive or negative effect. An inimical reaction<br />

brings on the fight response if one is angry and<br />

the flight response if one is insecure. We can alter<br />

our stress response from inimical to amicable<br />

and thereby cope with the stress stimulus.<br />

For example, let us say, to jump down to the<br />

ground from the roof, just 12 feet high, may be<br />

tremendously stressful for most of us. Majority<br />

of us, on looking down at the ground, would<br />

feel “butterflies in the stomach”. However, for a<br />

seasoned paratrooper, it would be fun. So, it is<br />

not the stressor (events, persons or environment)<br />

but our own interpretation and how we react<br />

decides whether we will get “stressed” or not.<br />

The Life Saving Stress Response<br />

The stress response in our<br />

body is meant for a protective<br />

and desirable reason. It is rather<br />

life saving. Evolution wise, our<br />

primitive ancestors, the Early Men,<br />

were exposed to various dangers at<br />

most unsuspected times - eg -when<br />

a hungry tiger suddenly pounced on<br />

them. To survive such flash emergencies,<br />

nature developed the “stress response” or “fight or<br />

flight” response in our body. Within milliseconds<br />

this would cause the heart to beat faster and<br />

more strongly and the blood pressure to rise (so<br />

that more and more blood laden with oxygen and<br />

glucose could go to the muscles, to either fight it<br />

out or run away). The breathing would become<br />

deep and extra glucose would be pumped into<br />

the blood by the liver, so that more of sugar and<br />

oxygen could be taken by the blood to the active<br />

muscles. Kidneys start saving water so that blood<br />

volume can increase, digestion reduces and<br />

blood from digestive organs is diverted to the<br />

active muscles. In addition, the blood clotting<br />

mechanism would increase so as to quickly seal<br />

off the wounds and minimize blood loss due to<br />

bleeding from injuries.<br />

So, where does all this fit into the problems<br />

of stress that we are talking about Well, the<br />

same stress response which was so protective<br />

during the evolutionary stages of human race<br />

has become a major hazard to our health. In<br />

our modern age life, we seldom face the kind of<br />

physical danger for which nature had designed<br />

the stress response. Even today, we need it on<br />

World Health<br />

Organisation<br />

The WHO expert committee defines<br />

Mental Health as ‘the capacity of an individual<br />

to form harmonious relations with others and<br />

to participate in or contribute constructively<br />

to change in the social environment’.<br />

some relatively uncommon occasions, as when<br />

suddenly threatened by a robber on a lonely<br />

track.<br />

The Harmful Stress Response<br />

We cannot have our body and mind in a state<br />

of alarm for prolonged periods of hours (may<br />

be, weeks or months continuously), to negotiate<br />

modern day “stressors” or challenges like having<br />

a difficult boss, staying separate from the<br />

family, preparing for an important competition,<br />

difficulties in career, or lesser difficulties like<br />

having a flat tyre while driving on the highway.<br />

Even for these small hassles, the body’s stress<br />

response remains massive or perpetual. The<br />

increase in blood pressure and heart rate,<br />

increase in blood sugar, increase in blood clotting<br />

mechanisms, muscles becoming taut, lowering of<br />

the immune defence of the body and reduction<br />

in the digestive process continue for long periods<br />

and lead to major diseases like hypertension,<br />

diabetes, peptic ulcer, infections, muscular and<br />

joint pains. It is therefore essential for us to learn<br />

ways and means to calm down our reactions to<br />

the stressor, and to develop adequate “coping<br />

mechanisms” to tackle the stressors of day-to-day<br />

living.<br />

The Adverse Effects of Stress<br />

Stress affects our health in a wide variety<br />

of ways. Psycho-somatic effects include IHD,<br />

hypertension, diabetes mellitus, peptic ulcers,<br />

predisposition to certain cancers, lowered<br />

immune functioning, arthralgias and myalgias,<br />

tension - headaches, etc. Emotional effects<br />

include suppressed hostility, anger, panic,<br />

irritability, “burnout”, fatigue, sleep disorders,<br />

anxiety and depression.<br />

Roadmap for Preventing and Managing<br />

Stress<br />

Learning and practising the power<br />

of “Now”. To have an intense awareness of<br />

the present moment, rather than brooding<br />

over the past which we cannot change, or<br />

contemplating about the future that we have<br />

no control over.<br />

Develop Personal Financial<br />

Management Skills<br />

Develop Time-Management Skills. Time<br />

is a premium entity. Managing available time<br />

in the most gainful and productive manner is<br />

a skill. Improper time management leads to<br />

procrastination and stress.<br />

Maintain Good Health. Even minor<br />

ailments such as common cold makes one<br />

feel demoralized; major diseases like diabetes<br />

would then certainly produce tremendous<br />

stress. One should therefore make conscious<br />

efforts to maintain good health and prevent<br />

such diseases.<br />

Undertake Regular and Brisk Physical<br />

Exercise and Yoga. Exercise leads to release<br />

of beta-endorphins which act on the brain and<br />

bring about a feeling of euphoria, well-being,<br />

confidence, alertness and decrease in pain<br />

sensations. This “high” state acts as an antidote<br />

to stress.<br />

Train the Family Members for Difficult<br />

Situations and Spend “Quality Time” with Your<br />

Family. One of the major precursors of stress is<br />

the feeling of being “isolated” or “disconnected”.<br />

When you spend quality time with your family<br />

members, you feel connected, without any feeling<br />

of isolation, which helps preventing stress.<br />

a particular task or favour being asked of you is<br />

unjustified or beyond your capabilities.<br />

Avoid Ego Struggles. We sometimes act as<br />

if it is more important to be seen as “right” rather<br />

than be happy. It is best to avoid the tendency to<br />

forcefully convince others when it is not so critical<br />

Practise Assertiveness skills. Assertiveness<br />

is the honest expression of what you feel and<br />

want from others, without trying to force them<br />

to give it. It is particularly useful when dealing<br />

with “difficult” people and the consequent stress.<br />

Some of the characteristics of assertive behavior<br />

which need to be developed are :<br />

‣ Speak up for yourself, for your needs and<br />

rights, while letting others speak for themselves.<br />

‣ Develop a sense of respect for yourself as well<br />

as for others.<br />

‣ Protest, maybe politely but definitely, against<br />

unfair treatment or unjustified criticism.<br />

‣ Take honest responsibility for your own<br />

wrongs / mistakes, but at the same time, do not<br />

take responsibility for someone else’s lapses.<br />

‣ Say “NO”, maybe politely, when you feel that<br />

to your own health and well-being. Doing so<br />

will help you escape a great deal of unnecessary<br />

stress.<br />

Develop Social Support Systems. It is<br />

a very wise investment to put in some effort to<br />

develop some close friends towards whom we<br />

can look up for support during stressful situations.<br />

Others<br />

Adopt traditional cultures<br />

Practise “Relaxation” techniques<br />

Progressive, deep muscular relaxation<br />

Practise methods to get a good sleep<br />

Spiritual Practices, Praying and Meditation<br />

and<br />

Promote humor and laughter<br />

Since the dawn of aviation industry we have<br />

had many accidents owing to marginal<br />

weather conditions. ‘Respect weather and<br />

decide in time’ is the golden rule and if adhered<br />

to will definitely help in preventing accidents/<br />

incidents.<br />

It was one of the monsoon months of 2009.<br />

I was posted to a premier fighter base in the<br />

Northern region. On this fateful day, I was part<br />

of a 4 ac formation tasked to carry out a dummy<br />

strike over another airfield in the J&K sector. The<br />

latter part of our route involved considerable<br />

amount of valley flying. I had recently attained<br />

my supervisory status and was quite eager to fly<br />

this mission. Due to bad weather at the target<br />

base our early morning scheduled take off got<br />

considerably delayed. Eventually by afternoon,<br />

on getting latest weather, we got airborne.<br />

The enroute weather was as predicted and<br />

did not hamper the safe transit till we hit the<br />

foothills. As we crossed over the first ridge line,<br />

the difficulty quotient of the exercise increased as<br />

it entailed RV with two ‘Tied Escorts’ in marginal<br />

weather conditions. A successful RV with escorts<br />

was achieved and the mission continued as<br />

briefed. Looking towards the hills along the<br />

planned route, I spotted a thick black layer of<br />

towering clouds. Out of sheer restlessness, I piped<br />

up on R/T for a weather update from an enroute<br />

fighter base. The feedback which we received was<br />

base specific and no update on weather over the<br />

hills was given. The Escort Leader also updated<br />

reasonable vertical development of this clouding.<br />

With every passing second the formation got<br />

closer and my restlessness kept increasing. Our<br />

six ac formation was a minute away from the<br />

planned intercept leg when broken clouding<br />

started interfering with our formation keeping.<br />

The formation leader ordered a few side steps to<br />

avoid patches of clouds. I was sure the formation<br />

members must have felt uncomfortable flying in<br />

that scenario.<br />

Soon, the escorts were out of sight as they<br />

resorted to height separation due to clouding. The<br />

formation keeping was getting challenging and<br />

the situation was expected to get worse once the<br />

tactical action would commence which included<br />

loss of contact, height separation, escape routes<br />

etc. With the increase of clouding my discomfort<br />

10 Aerospace Safety J u n e 2 0 1 2<br />

INDIAN AIR FORCE


level was rapidly increasing. Eventually, I piped up<br />

on R/T and asked the leader to abort the mission.<br />

I expected a positive reply and mentally prepared<br />

myself for subsequent actions. However, when<br />

the leader called to ‘continue’, I was shocked.<br />

My professional competence was getting<br />

sandwiched between taking a safe decision and<br />

continuing with the mission. Our formation also<br />

had pilots with lesser experience who were also<br />

continuing without expressing their discomfort.<br />

The reason for their silence was not difficult to<br />

predict at that moment. They behaved as true<br />

followers with immense faith in their leader. This<br />

fact hit my professional ego - ’if they could do it<br />

then why not me’. The ‘Formation’ integrity was<br />

being challenged at every step due to extended<br />

trails of clouding and the worst was yet to come.<br />

Finally, one of the junior pilots expressed his<br />

discomfort on R/T and requested to abort the<br />

mission. By this time our ‘Formation’ had already<br />

entered the black turbulent wall of clouds. A<br />

turn about was ordered after establishing height<br />

separation which was a bit relaxing but a big<br />

challenge of avoiding a mid air collision loomed<br />

large! Our ‘Formation’ at this time was over the<br />

hills where the ‘Route Safety Altitude’ was as<br />

high as 16500’. The ordered maneuver was being<br />

executed with standard height separation.<br />

A conventional turn-about in a large formation<br />

in perfect VMC requires clearances from various<br />

members to avoid collision whereas in the said<br />

condition it was getting executed in nil visibility<br />

conditions, without any clue of relative positions<br />

of the other members! The turbulence was so<br />

severe that 1000’ height separation appeared<br />

very less. All of us were flying on instruments<br />

and struggling against turbulence to maintain<br />

flying parameters. The thought of other aircraft in<br />

close proximity was the scariest of all. The stage<br />

was all set for disorientation i.e large formation,<br />

height maintenance, turbulent weather and nil<br />

visual references. The silence was broken by two<br />

R/T calls- first one of ‘HUD failure’ from No.2 and<br />

the second of ‘TGT Amplifier failure’ from the<br />

formation leader.<br />

After a long battle (short on time domain)<br />

with our machines and weather, the formation<br />

eventually broke clouds. The sky was visible in<br />

patches. It took another couple of minutes and a<br />

long series of R/T calls and aircraft manoeuvring<br />

before we could re-establish our formation and<br />

recover at our base. During the mission debrief<br />

few more tales about individual discomfort<br />

came to light and the scariest amongst all<br />

was the one associated with ‘HUD failure’. ‘All<br />

is well that ends well’ applied perfectly to our<br />

formation<br />

A few lessons emerged out of this incident<br />

which should make us wiser :-<br />

‘Respect Weather’- universally published<br />

but least followed.<br />

A perfect balance should be maintained<br />

between professional ego/competence and<br />

safety.<br />

Every member of a formation is equally<br />

responsible for formation safety. Decide and act<br />

in time before things go out of hand.<br />

Formation leaders must take decisions<br />

based on the least experienced member.<br />

Respect decisions of juniors as well.<br />

Do not let your ego overpower a safe<br />

decision.<br />

During peace time missions do not push<br />

your luck too hard for it to favour you on every<br />

occasion.<br />

Peculiarity of weather over hills should<br />

be emphasized in detail for missions involving<br />

valley/hill transit.<br />

Let your experience benefit others for a<br />

better flight safety environment.<br />

Safe guarding the EEZ and sea lanes is<br />

required, keeping in view that India is an<br />

emerging market, with a rapid growth in sea<br />

trade. Thus, to ensure unhindered growth rate,<br />

the EEZ and sea lanes need to be kept safe and<br />

secure all the time. To achieve the said objective,<br />

the <strong>Indian</strong> Armed forces have embarked on the<br />

modernization of Air and Naval forces. The <strong>Indian</strong><br />

Air Force has increased the quantum of maritime<br />

operations in its island regions, scheduled<br />

couriers operations and various detachments.<br />

The surface of the earth is covered by 71%<br />

water and 29% land. Flights over the oceans<br />

have few or no diversions. Consequently,<br />

communications and navigation, which are<br />

essential for conduct of any flight, are also limited<br />

due to the vast distances between successive<br />

stations. The following are some hazards that are<br />

associated with flying over the sea: -<br />

Long Eventless Flights. Long flights as said<br />

earlier, are a feature of sea flying. Though they<br />

appear innocuous to pose a threat, they may lead<br />

to one. Lack of any significant activity on a long<br />

leg leads to boredom and may result in reduced<br />

level of alertness in the cockpit<br />

.<br />

There have been accidents/ incidents due<br />

to crew not being alert. The only answer to the<br />

reduced alertness is strict discipline and training,<br />

which ensures that all the crew members are<br />

alert, and in case of any deviation, raise the<br />

alarm so that the situation is contained before it<br />

deteriorates.<br />

Disorientation. The horizon over sea is<br />

different from the usual blue over brown. This is<br />

taught to a pilot. Due to the large blue sea and<br />

similar coloured sky the horizon may be nondistinct<br />

for someone in an unusual attitude.<br />

In an accident in 1978, Air India Flight - 855,<br />

Boeing 747 crashed into sea 3 km off the coast<br />

of Bombay. Investigation revealed that the pilot<br />

executed a standard right turn after take-off into<br />

the Arabian Sea. Then the aircraft was returned<br />

to wings level condition briefly and then started<br />

rolling to the left from which it never recovered<br />

and crashed into the sea.<br />

The flight was being conducted in the<br />

evening hours. It was attributed to disorientation<br />

of the pilot due to artificial horizon failure. Lack<br />

of adequate visual references over sea added to<br />

the cause.<br />

To prevent the occurrence of disorientation,<br />

it is essential that the training pattern involves<br />

sufficient instrument flying and instrument<br />

approach procedures. This builds the confidence<br />

of aircrew in flying totally on instruments<br />

during poor weather and poor lighting<br />

conditions. Further, the aircrew should recognise<br />

disorientation and declare it to other members so<br />

that corrective action can be initiated well in time.<br />

Present courses conducted at IAM would go a<br />

long way in exposing the aircrew to disorientation<br />

and the corrective actions thereafter.<br />

Communication and Navigation. Due to<br />

large separation between one station and the<br />

other on oceanic routes, there are significant<br />

gaps in communication and navigation<br />

coverage. There are only a few stations that<br />

provide communications over oceanic routes.<br />

Communication is reliant for the most part on<br />

HF and satellite communications. However, even<br />

advanced communication systems may not serve<br />

the purpose at times, as was seen in the Air France<br />

Flight 447’s case. The flight was flown at 35000’<br />

and even at the time the aircraft crashed into the<br />

sea there was no communication regarding their<br />

emergency.<br />

Navigation over oceans suffers from large<br />

gaps in coverage from ground stations and the<br />

lack of ground features makes it all the more<br />

susceptible to failure. The only aids at the<br />

disposal of the aircrew are satellite navigation<br />

systems. But over-dependence on one system is<br />

not always prudent.<br />

INDIAN AIR FORCE 2 0 1 2 J u n e Aerospace Safety 13


At present on our couriers flying oceanic<br />

routes, the sole means of communication is the<br />

HF for obtaining weather and other information.<br />

The HF system employed suffers many limitations<br />

due to ageing and interference. This places<br />

additional work load on aircrew in terms of<br />

updating of information for diversion.<br />

Diversion. A major consideration when<br />

flying overseas is the non-availability of diversions<br />

en-route. There may only be a few routes that<br />

have an island en-route with an airfield that<br />

could serve as a diversion. Otherwise, there are<br />

none available on most of<br />

the routes. Therefore any<br />

critical emergency which<br />

otherwise requires aircraft<br />

to divert, would require<br />

ditching over sea due to lack<br />

of diversions. Calculations<br />

of Critical Point and Point of<br />

No Return assume greater<br />

significance in oceanic route<br />

flying.<br />

alike for decades. Most of<br />

the convective weather<br />

phenomena that occur<br />

over land originate over<br />

the sea. The large amount<br />

of moisture available<br />

over oceans gives rise<br />

to weather developing<br />

in a short span of time,<br />

making it unpredictable<br />

and intense in nature.<br />

Weather radar is therefore<br />

a pre-requisite on oceanic<br />

routes. Weather check<br />

through R/T from other<br />

aircraft ahead / behind<br />

on the same route also<br />

helps. Briefings must take into account sea<br />

surface temperature and lapse rate over the areas<br />

being flown as they give an idea of the build up<br />

expected.<br />

Ditching. The term ditching is synonymous<br />

with forced landing on land. Ditching is also a<br />

procedure to recover aircraft on water.<br />

The statistical chances of surviving a<br />

ditching are high. It is estimated that 88% of<br />

controlled ditchings result in few injuries to<br />

pilots or passengers. You are more likely to die<br />

Weather. Ocean<br />

climatology has always been<br />

a subject of mystery to the<br />

aviator and meteorologist<br />

after ditching by drowning, usually hastened by<br />

hypothermia and exhaustion. By wearing a life<br />

jacket in the aeroplane your survival prospects<br />

are greatly improved. However, in cold water, that<br />

is 15 degrees Celsius or less, or life expectancy in<br />

the water is only about one hour.<br />

There are various other issues that have to be<br />

borne in mind while ditching. One of the most<br />

difficult things to get right in a ditching is judging<br />

the height for the round off. Most aircrew would<br />

not have experienced landings without an<br />

undercarriage. Thus you will be used to seeing a<br />

particular attitude at the round off. In the ditching<br />

case that attitude will be a little different because<br />

the aeroplane should be a little closer to the<br />

surface, to cater for the lack of an undercarriage.<br />

In general terms it is always preferable to<br />

impact the water as slowly as possible, under<br />

full control; but do not stall the aeroplane. Keep<br />

the wings parallel to the surface of the water on<br />

impact, i.e. wings level in calm conditions. One<br />

wing tip striking the water first will cause a violent<br />

uncontrollable slewing action.<br />

Ditching into the face of the swell or into<br />

waves should be avoided because the aeroplane<br />

will behave in a similar manner to one impacting<br />

a cliff face. There are many other factors that<br />

go into a successful ditching like the design,<br />

condition of sea, winds etc at the time of ditching.<br />

It will suffice to say that there is a fair amount of<br />

risk involved.<br />

After a successful ditching, the next task will<br />

be of survival. Needless to say, it isn’t easy and is<br />

inversely proportional to the amount of time spent<br />

at sea. Type of survival equipment, proximity to<br />

the coast and rescue team’s equipment would<br />

all affect your chances of survival. Regularly and<br />

(more importantly) seriously practising ditching<br />

drills helps keep presence of mind in actual<br />

situations.<br />

What is safety culture Who and what<br />

we are, what we find important and<br />

how we go about doing it correctly, is<br />

called Safety Culture. The possession of a safety<br />

management system, no matter how thorough<br />

and systematic it may be, is not sufficient to<br />

guarantee sustained safety performance. To<br />

proceed further it is necessary to develop cultures<br />

that support higher process such as ‘thinking the<br />

unthinkable’ and being highly motivated to be<br />

safe, even when there seem to be no obvious<br />

reasons to do this. But the challenging part here<br />

is of creating a healthy safety culture and keeping<br />

it alive.<br />

We need to adopt a safety culture and<br />

refine it continuously to achieve hole-proof safe<br />

environment around. But it is natural human<br />

behaviour to get used to a particular set of<br />

conditions or environment and resist change.<br />

You can easily understand this trait if you happen<br />

to play golf. When you start the game, you learn<br />

a particular swing and continue to practise.<br />

After years of game, you may be advised by a<br />

professional to adopt a change in your technique<br />

to get a few extra yards. That is the most difficult<br />

time, wherein you are in a period of transition.<br />

You feel like giving up the game because you<br />

are not able to train yourself with respect to that<br />

technique. But it is only through your patience<br />

and belief that you can overcome this situation.<br />

On the same lines, we continuously need to<br />

upgrade our safety culture in order to achieve<br />

few extra yards of safe environment, inspite of<br />

difficulties we are likely to face.<br />

Recently, I read about five types of safety<br />

culture, that are enumerated as follows:-<br />

We care less about safety than about not<br />

being caught.<br />

We look for fixes to accidents and incidents<br />

after they happen.<br />

We have systems in place to manage hazards<br />

(however the system is applied mechanically).<br />

We follow the procedure but do not necessarily<br />

believe these procedures are critically important.<br />

We have systems in place and we genuinely<br />

belief that safety is genuinely worthwhile.<br />

Safety behaviour is fully integrated into<br />

everything we do.<br />

We may decide on our own in which category<br />

our safety culture falls. But whatever level it may<br />

be, the aim is to achieve the fifth level where safety<br />

behaviour is fully integrated into everything we<br />

do.<br />

The underlying reason why cultural change<br />

often fails to succeed is that the new situation is<br />

unknown to the participants. We often believe<br />

that the current situation is as good as it gets and<br />

there is little scope to change.<br />

Change agents are like golf professionals.<br />

They can help develop a person’s game, but they<br />

can’t play it for them. The greatest single barrier<br />

to achieve success however, is the belief that it is<br />

too difficult. On the contrary, in the long term it is<br />

more difficult and dangerous not to!<br />

After my Stage 3 training on Kiran MK-II<br />

aircraft, I was posted to my first Fighter<br />

Squadron at a premier Fighter base in the<br />

West, for MOFT syllabus on MiG-21 T-96 aircraft.<br />

The morale was high and so were the spirits. The<br />

station housed two fighter squadrons operating<br />

the same type of aircraft. So, the atmosphere<br />

with 22 flying officers from Sem I & II wasn’t<br />

very different from that in Training Command.<br />

Every morning ushered in unlimited visibility<br />

and high serviceability; one could hear reheat<br />

after reheat, and it filled us with thrill. Soon, my<br />

ground training was over and I commenced<br />

flying on what was called the real fighters. She<br />

was sleek and fast and could take anyone for a<br />

ride. The time on downwind got over in a flick<br />

and there was no time to get our parameters and<br />

carry out vital actions, leave alone the situational<br />

awareness on the circuit traffic. A few days later,<br />

the first guy in the course cleared his solo check<br />

and was launched in a fighter for his first solo.<br />

With most of us due for our solo checks in a few<br />

days, we proceeded along with the ACP pilot to<br />

see the first solo landing of our course. He was<br />

our very own - Callsign 919.<br />

After about 20 mins, we heard Callsign 919<br />

on R/T for the rejoin. He reported dead side and<br />

turned downwind. In the first overshoot, he was<br />

correctly on glide path, after which he turned<br />

for downwind. In this time, Prowler formation<br />

that had gone for a Basic Flying Manoeuvres<br />

sortie to the sector, too had rejoined. Prowler<br />

– 2, a Sem II trainee, joined circuit behind 919,<br />

and the leader maintained overhead to regulate<br />

gravy. 919 reported downwind, followed by<br />

Prowler 2. I picked him up visually on finals - but<br />

wait a second! These were two aircraft in close<br />

proximity!! 919 while carrying out his downwind<br />

vital actions had delayed his baseleg turn and<br />

Prowler – 2 had turned at the correct baseleg<br />

turning point. As a result when prowler-2 rolled<br />

out on finals he was dangerously close to 919.<br />

The ATC in a panic, gave a call to Prowler-2 to go<br />

around and 919 to continue. However 919 also<br />

initiated go around in a panic. The ACP pilot<br />

intervened and told Prowler-2 to go around on<br />

dead side. On seeing 919 in such close proximity<br />

while going around, Prowler-2 put on a vicious bank<br />

with undercarriage and flaps down and yanked<br />

back towards dead side. The ACP pilot in a horror<br />

yelled on R/T to offload, but the aircraft with nose<br />

up and at very low speeds continued towards dead<br />

side and started a wild wing to wing rocking which<br />

is a symptom of approach of stall. But much to<br />

everybody’s relief, it thereafter gradually lowered<br />

nose, and spaced out to the correct dead side. Both<br />

aircraft were recovered safely subsequently.<br />

Lessons Learnt<br />

The first solo had no SA of any other aircraft<br />

on circuit; he was too busy carrying out his own<br />

checks and maintaining parameters as accurately as<br />

possible.<br />

Prowler – 2, a Sem II trainee, happily assumed<br />

that the traffic ahead would be maintaining correct<br />

circuit pattern and was taken by surprise when he<br />

saw the aircraft ahead going around.<br />

The MiG-21 requires careful handling at<br />

low speeds and such incidents can be avoided by<br />

adhering to simple practices like making visual<br />

contact with traffic ahead, and if no contact, by<br />

confirming traffic on R/T.<br />

After both aircraft landed, ACP pilot said “This is<br />

exactly what you should NOT DO...Remember this<br />

Black Demo”.<br />

The day before our first para-jump, the<br />

instructor demonstrated all possible<br />

malfunctions that one might encounter.<br />

After watching a total malfunction,<br />

i.e. failure of the parachute to deploy, one<br />

of the students asked: “If we have a complete<br />

malfunction, how much time do we have to deploy<br />

our reserve parachute”<br />

The Instructor replied: “You have the REST of<br />

your life to deploy that reserve!”<br />

Safety is not just a set of rules that we follow ow<br />

to achieve our overall aim. Safety means<br />

delineating risks and then managing them in<br />

all aspects of life. A lot matters on the objectives<br />

and the way of thinking of like-minded people who<br />

constitute the society. I am reminded of an incident<br />

that once took place in the Southern region. The<br />

very thought of it still makes me shiver. I was<br />

authorized for a local flying sortie in SU-30 MKI<br />

within LFA. Sortie was uneventful till we landed<br />

and switched off. During switch off, I realized that<br />

the controls deflected to the maximum as soon as<br />

the AC generators cut out! This would happen only<br />

if I had, by mistake, switched off the batteries (only<br />

power source available to the aircraft after switch<br />

off ) before run-down. But this was not the case.<br />

My inquisitiveness pushed me to explore various<br />

possibilities that could have led to the unexplained<br />

deflection. Perturbed by everyone’s finger pointing<br />

at me, I was frantic to find out what actually had gone<br />

wrong I went back to the cockpit and selected the<br />

battery on. I noticed the voltmeter needle stuck at<br />

zero. I was shocked to see this and for once thought<br />

this was not happening. I soon realized that the<br />

aircraft that I just landed did not have a single<br />

battery in it! The Battery acts as a standby source<br />

of power to the aircraft, should the generators fail.<br />

This meant that if I had a twin AC generator failure, I<br />

had no reaction time available. The aircraft controls<br />

would have immediately deflected out of control<br />

and the aircraft would have gone into an unusual<br />

attitude, one from which a safe ejection may not<br />

have been possible.<br />

The incident was to happen and it did. Handling<br />

the case was in the hands of superiors and the way<br />

this incident was handled exposed our approach and<br />

means towards the Flight safety. Our investigations<br />

and procedures are mostly result based. This incident<br />

explained it all to me. Result of an uncontrolled<br />

deflection of controls on ground and that in air<br />

could have had drastic differences in their outcome.<br />

ln most cases, our source finding mechanism works<br />

in proportion to the damage caused/ result of<br />

the incident/ accident. If the damage was minimal,<br />

the source/ cause may not be important. But if the<br />

same<br />

event<br />

had<br />

a severe<br />

consequence,<br />

the reason would<br />

assume<br />

great<br />

importance.<br />

Hence<br />

the “cause-result” esu bias. In<br />

the incidentid thatt I<br />

mentioned, the<br />

cause was grave but since the result was insignificant,<br />

not much attention was given to the cause, even<br />

though it had the potential of fatal consequences.<br />

Though we assume that being in the armed<br />

forces, our thoughts and views are similar, it is never<br />

so. As far as this incident was concerned, within the<br />

station most of those involved in the reporting chain<br />

were of the opinion to avoid reporting the incident.<br />

They seemed oblivious of the fact that ignoring it<br />

today could cost someone’s life tomorrow. However<br />

due to the able leadership of the then Commanding<br />

Officer, the matter was brought to light and others<br />

got to know about it. Here comes the role of<br />

collective psyche. There is a disturbing tendency<br />

to consider a problem ‘hidden’ as the problem<br />

‘solved’!! (The classical ‘ostrich mentality’). This<br />

may provide short term relief, but in the long run<br />

it will catch up, having become bigger than before.<br />

In this incident, one man stood against a plethora<br />

of opposition from all around. The courage and<br />

guidance that the CO instilled by reporting such<br />

an incident was exemplary. We all must endeavor<br />

to follow and preach truth and have the courage to<br />

face difficulties, no matter how strong they are or<br />

from whom they come. To be able to provide a safe<br />

flying environment, the first step would be to make<br />

a radical change in our way of thinking.<br />

I<br />

was a young Flying Officer posted to a Bison<br />

Sqn, in one of the premier Air Force Bases<br />

of the country. I was new to the fleet after<br />

finishing my training on Hawk MK-132. After<br />

completing my initial Dual Checks on the MiG-21,<br />

I was cleared to fly solo.<br />

It was a bright sunny day and I was authorised<br />

to fly my sixth solo on type. After carrying out the<br />

sortie as briefed to me, I initiated rejoin in time and<br />

with adequate fuel, keeping in mind the traffic of<br />

the seven flying units of the station. I asked the<br />

radar controller for a GCA, he made me orbit over<br />

a point 30 km from base, after confirming fuel<br />

from me, to accommodate departure of a 4 ac<br />

formation.<br />

No. 1 of the 4 ac formation was asked to abort<br />

take off due bird on R/W. He had rolled, hence<br />

switched off on R/W. At this point of time, I was<br />

asked to divert to my primary diversion. On<br />

initiating diversion, I realised the fact that I had<br />

not carried out a diversion before, and coupled<br />

with fuel below thirsty fuel figure, a chill ran down<br />

my spine. I was calming myself down and telling<br />

myself not to panic. Things were going smoothly<br />

and I was 50 km out of base, when I was informed<br />

that I could turn back as the R/W was now clear.<br />

Happily I turned back, thanking the Almighty as<br />

there was nothing like landing at your home base.<br />

A minute later while on inbound course,<br />

to my horror, I was informed that the R/W was<br />

blocked again and therefore I was to divert. (This<br />

happened because the ambulance which was<br />

following the CFT, while clearing off the R/W,<br />

rammed into it, leading to fatal injuries to the MTD<br />

of the ambulance and blocking the R/W). Cursing<br />

everyone, I turned back. Looking at the fuel<br />

gauge, I was unsure if I would be able to make it.<br />

A slight amount of panic had crept into me. I told<br />

myself not to panic, remembering my instructor’s<br />

golden words, “if you panic, half the battle is lost”.<br />

About 60 km short of my diversionary airfield,<br />

my ‘450 litres remaining’ warning light started<br />

flashing. Keeping my cool, I went over the ejection<br />

procedure in my mind. I asked<br />

for a direct vectoring for finals.<br />

Considering the way fate had<br />

been turning out, there still<br />

were segments of luck that<br />

had remained functional. nal.<br />

To my relief and delight, I<br />

found that the R/W in use<br />

was along my track. All<br />

warning lights related<br />

to fuel had illuminated<br />

except for ‘service<br />

tank’ light. I touched<br />

down with barely 150-<br />

200 litres on board.<br />

Following me were six<br />

more aircraft from the<br />

same base, all low on<br />

fuel. “All is well that<br />

ends well”! But the<br />

lessons learnt that<br />

day were:<br />

Whenever<br />

in an unfamiliar<br />

situation, do not<br />

panic.<br />

Keep you<br />

calm and continue<br />

normally, rather than<br />

doing something<br />

stupid in haste.<br />

Do not be in<br />

a decision dilemma;<br />

when you have initiated<br />

a diversion continue<br />

with it. In retrospect, I<br />

should have continued<br />

with the diversion at the<br />

first instance, rather than<br />

turning back for base, only<br />

to be asked to divert once<br />

more.<br />

It was Oct 07, and we were at one of the most<br />

picturesque locations that we could have<br />

been in. 3000 km away from our Nation, our<br />

12 immaculately maintained, saffron coloured,<br />

appropriately labelled “Ambassadors of the IAF”<br />

Suryakiran Aerobatic Team aircraft, were parked<br />

on an island, wing to wing with a plethora of the<br />

latest generation fighters. The Royal Air Force RED<br />

ARROWS team too was alongside. We were at the<br />

Langkawi International Maritime and Aviation<br />

Show (LIMA 07), in Malaysia, having flown in via<br />

Myanmar and Thailand.<br />

The occasion was momentous, as it was<br />

the world that waited to watch our skills – the<br />

stakes were very high. It urged us to perform<br />

24 Aerospace Safety J u n e 2 0 1 2<br />

INDIAN AIR FORCE


with the highest levels of professionalism, and most<br />

importantly - “THE JOSH” – the main ingredient of<br />

the recipe in mission accomplishment by all fauji<br />

groups. Thanks to oodles of man-hours spent on<br />

planning the trip, the ferry to Langkawi island was<br />

accomplished with picture perfect precision.<br />

We were on with our routine series of displays,<br />

usually two in a day. As the routine demands, the<br />

men with spanners (that’s what the technical team<br />

are playfully called) were the first to reach early in<br />

the morning to prepare the 12 aircraft in various<br />

configurations for the display. Third day into the<br />

air show came the moment which changed my<br />

approach towards life as an engineer. With 2 years<br />

of experience at that time, I undertook a snag<br />

rectification, which back home in India we could<br />

only dream of accomplishing (though we don’t<br />

want such snags to occur at all in the first place).<br />

As we walked towards the tarmac with our team<br />

of technicians, a usual panoramic glance of all the<br />

12 aircraft to ascertain safety (to rubbish the fear<br />

of someone stealing our machines!!) was the usual<br />

practice. However, today it left us flabbergasted.<br />

What we saw (hold your nerves) was a machine<br />

gun, yes a machine gun, standing on its tripod, on<br />

the port wing of one of our aircraft, with its bayonet<br />

pierced right through the wing surface that had<br />

resulted in a rupture of the aircraft skin. The sight<br />

of such a damage shook us to the core. At first sight,<br />

from a distance, it looked unreal and improbable,<br />

but disbelief turned to reality as we drew up close.<br />

We found out that there had been a para trooping<br />

accident the night before. A miscalculated wind<br />

pattern had resulted in the paratroopers of the<br />

RMAF descending on the tarmac, which sadly<br />

resulted in one of them sustaining fatal injuries too.<br />

But the show had to go on.<br />

As the SEO of the detachment, I called<br />

my Detachment Commander and my Flight<br />

Commander to break the news of the incident, and<br />

what followed was a flurry of calls to and from our<br />

parent base and higher ups back home (I remember<br />

it was a Sunday morning). Our team of technicians<br />

assessed the damage on the wing, and the silver<br />

lining to the incident was that the gun’s bayonet<br />

had missed the fuel tank by about 5 cms. So, now<br />

all we had to do was structural repair work on the<br />

wings. This is a task that in India mandates an<br />

activity from fourth line agencies and specialist<br />

structure repair teams. In the case of KIRAN aircraft,<br />

this only is possible at HAL Bangalore Division. As<br />

per our contingency plans, a team of HAL was ready<br />

for airlift, in case required.<br />

This was the point where we had to decide<br />

expeditiously of what to do. I quickly contacted<br />

the fourth line agency of Royal Malaysian Air Force,<br />

and showed them the damage. They assessed the<br />

damage, but due to international issues refused<br />

to work on our aircraft. However, they offered to<br />

provide us all the raw materials required for the<br />

structure’s repair. This was a welcome moment for<br />

our Airframe tradesmen, who always excelled in<br />

their work as usual. Well, a phone call to our mother<br />

base at AFS Bidar to take an official nod from our<br />

Senior Engineer (Aircraft) and our Chief Engineering<br />

Officer, and we were underway with our work in less<br />

than two hours of the first sighting of the damage.<br />

A few necessary supervisory checks, and a<br />

mandatory ground run to ascertain all hydraulics<br />

and fuel system components were fine, and our<br />

aircraft was ready for its Air-Test post rectification<br />

in less than 24 hours. Being an aerobatic aircraft,<br />

which is constantly subject to high G-loads and<br />

stresses, any structural work is always very critical<br />

and needs to be done with utmost care and<br />

perfection. The Aircraft was check flown by our<br />

Flight Commander, as the aircraft belonged to his<br />

position in the formation (for those who may not be<br />

aware, in any formation flying team, the aircraft are<br />

generally kept position specific and pilot specific<br />

(this is always the endeavour of the technical team).<br />

The aircraft started up and taxied out with shouts of<br />

hurray on the tarmac, but the test was yet to come.<br />

We monitored the sortie on RT and did not hear<br />

anything abnormal, and the aircraft taxied back<br />

with a happy looking Flight Commander emerging<br />

from it (I was too apprehensive, in retrospect),<br />

INDIAN AIR FORCE 2 0 1 2 J u n e Aerospace Safety 25


further enhancing the jovial atmosphere that we<br />

always create in adverse conditions. However, the<br />

Flt Cdr to our horror at that time remarked “Guys<br />

what have you done with the machine” and here<br />

was a moment I must admit, my heart skipped<br />

a beat. He quickly sensed the tension and eased<br />

it out by saying that the machine infact handled<br />

very well in air and an age old snag of an inherent<br />

right roll beyond some speeds in that particular<br />

aircraft was not present now. The divine stab of the<br />

bayonet had killed it!!<br />

We all celebrated as this aircraft flew snag free<br />

in all displays and ferried back to Bidar successfully,<br />

where upon landing it was put down by base CEO<br />

for intricate checks by the HAL team specialists who<br />

were amazed to see the workmanship of our very<br />

own Airframe tradesmen with scarce resources and<br />

a few facsimile photocopies<br />

of the Airframe Manual<br />

to refer to, and<br />

had<br />

declared<br />

the aircraft fit to<br />

fly. We learnt the<br />

following<br />

lessons<br />

from this episode as<br />

engineers in the field<br />

of aviation.<br />

A dynamic and professional problem solving<br />

ability exists in all individuals and must be showcased<br />

To have an eye for detail and to be aware of<br />

your resources at all times.<br />

To think about flight safety implications in all<br />

actions, as one wrong step can prove catastrophic in<br />

this field.<br />

Be confident of your abilities but not<br />

complacent, due to over confidence.<br />

Trust and exploit your own capabilities and<br />

recognize hidden skills within your own group. This<br />

may not only save the exchequer, but also save<br />

critical operational time and inculcate a sense of<br />

belief and confidence in our extremely talented and<br />

skilled manpower.<br />

I<br />

was a young flying officer full of spirit and<br />

aspiration just posted to a Sqn. After lot of<br />

studies, ground training and spending hours in<br />

the cockpit (the ac being on ground), we started<br />

flying the MiG-21. It was my third solo sortie<br />

wherein I was supposed to fly a handling profile<br />

in sector. The sortie was uneventful till rejoin on<br />

downwind, when after lowering u/c, my main<br />

hydraulic failure warning came on. I declared the<br />

emergency, then took a moment to ascertain the<br />

situation and went over the actions. I reported<br />

dead side again, completed my actions and landed<br />

off a flapless approach in the next circuit which<br />

is considered quite tricky on the MiG-21. I was<br />

debriefed the following day, in fact I was praised<br />

and my actions at such limited experience were<br />

appreciated. I was quite happy with myself and<br />

continued flying with a newly gained confidence.<br />

I even got a commendation through the flight<br />

safety channel for my emergency handling.<br />

But about six months down the line when<br />

I gained sufficient experience on the MiG-21,<br />

I realised that my actions had not been very<br />

correct, in fact they were wrong. When I realised<br />

that I had an emergency on downwind, all I had<br />

to do was continue in the circuit and land. But<br />

I elected to go around and carry out one more<br />

circuit which could have led to an aircraft fire as I<br />

already had a hydraulic leak.<br />

All is well that ends well. But the point to<br />

ponder is that why was this point not brought<br />

out to give a lesson to other youngsters in the<br />

Sqn. In the interest of Flt Safety, I write this and<br />

implore those young pilots flying this aircraft<br />

to apply system knowledge to the emergency<br />

encountered so that they do not land up<br />

complicating the emergencies encountered.<br />

Somebody asked me recently whether you<br />

can get lost in an aircraft. The uncertainty<br />

that existed was complemented by a<br />

simple question, since you could see everything<br />

from the air, can’t you find your way out<br />

For a Dornier pilot, I was blessed with the<br />

best avionics in the Naval inventory. The ways<br />

of ‘FIXing’ yourself were many – GPS, VOR track<br />

and range, VOR track intersection, NDB bearing<br />

intersection, etc to quote a few. If all else failed<br />

and still lost ask the nearest control for bearing<br />

and distance to base.<br />

Going down memory lane I remember<br />

an eventful sortie from the time when I was<br />

instructing at Air Force Academy.<br />

For those who missed the HPT-32 phase, a<br />

transition from a Dornier back to HPT-32, is like revisiting<br />

the Stone age. None of the navigational<br />

aids listed above exist and we start with the last<br />

quoted statement “If all else failed......!!”<br />

It was another one of those sorties in<br />

marginal weather conditions when training had<br />

to be progressed and the instructors were being<br />

pushed to undertake sorties. The trainee was<br />

in his pre-solo phase. I was ordered to progress<br />

general handling part of the sortie with a promise<br />

that a flex sortie would be accommodated later<br />

for teaching circuits. We were airborne for about<br />

20 minutes when the weather deteriorated at<br />

base. All aircraft were recalled using homing<br />

(Radar was then unavailable at AFA). Three aircraft<br />

rejoined. Two were still left in air and unluckily, I<br />

was the farthest out (Junior most instructor gets<br />

the farthest sector!)<br />

It is pertinent to remind the readers of some<br />

salient features of the HPT-32 aircraft at this<br />

stage. Firstly, the aircraft has a Direction Indicator<br />

(DI) which is a pure gyro with no magnetic input.<br />

The DI has to be synchronised with compass<br />

every now and then (known as the DISCo check –<br />

stands for DI Synchronised with Compass). A very<br />

often neglected check, but very critical in finding<br />

out the direction once the homing is given.<br />

Secondly, there is no navigational aid other than<br />

the eyeball. With minimal visibility, that luxury is<br />

also withdrawn. Thirdly, it does not have a radio<br />

altimeter which gives the altitude AGL which is<br />

most essential when you go below the clouds to<br />

check your position.<br />

The max speed of 200 kph minus head wind<br />

speed of 50 kph, gives a very slow ground speed,<br />

and I re-emphasise “kilometres per hour” and<br />

not “knots”. The stalling speed is 115 kph (clean<br />

configuration). While heading towards the base<br />

on the homing given at full throttle, the next<br />

call from ATC asked us to maintain in sector at<br />

endurance settings since the visibility was now<br />

nearly zero. Since only two aircraft were in air,<br />

I asked the other instructor who was closer to<br />

the base (who happened to be an IAF Dornier<br />

pilot incidentally) to find out how bad it was. He<br />

informed me that he was already in circuit area<br />

and was only getting glimpses of the runway at<br />

circuit height.<br />

The pupil, till now, a neglected factor, piped up<br />

to tell me, “Sir, I think the compass in not moving”.<br />

After asking him to carry out the “DISCo”, I realised<br />

that he was talking about the magnetic compass<br />

(the only reliable instrument on the aircraft). It<br />

seemed stuck. Now the chances of getting lost<br />

were increasing. I descended to the minimum<br />

sector altitude to find a very familiar way point<br />

quite close to base. Being in and out of clouds<br />

and through the small window within the cloud, I<br />

decided not to lose sight of that way point.<br />

So instead of maintaining at endurance<br />

setting, here I was, at full throttle carrying out<br />

continuous steep turns, one to avoid losing sight<br />

of the way point, and second, to get my compass<br />

back on line. A Lot of banging on the compass<br />

followed. But the compass refused to budge. The<br />

ATC confirmed from me regarding endurance.<br />

With no sign of recovery of the compass, I heard<br />

the other pilot informing that he is on downwind<br />

with the runway in sight. Navigating with the<br />

road which leads from the way point to the main<br />

gate of AFA, I informed ATC that I was heading to<br />

base at minimal height.<br />

Soon, I saw myself very high on top of the AFA<br />

main gate which is too close to the runway for a<br />

comfortable approach and not in sight of the<br />

preceding aircraft, I managed a fleeting sight of<br />

the runway and decided to make the approach.<br />

Throttle closed and gliding to where I thought the<br />

runway threshold is, I gave a call to the preceding<br />

aircraft –“Confirm landed”. “Affirm” – came the<br />

reply. All was well and I found the threshold<br />

winking at me at 100 m AGL. Speed was about<br />

230 kph. (Max threshold speed for the aircraft<br />

is 180 kph to cater for the main wheel touching<br />

down instead of the nose). With throttle closed<br />

from top of descent, there is no other way to<br />

reduce speed. Visibility was about 200 m. Finally<br />

I rounded off and maintained at round off height<br />

to wait for the speed to reduce. Speed dropped to<br />

about 190 kph.<br />

And then, I saw funny sight, there was an<br />

aircraft ahead of me moving very slowly on the<br />

runway. As it became larger, I checked with the<br />

tower whether any aircraft was on runway. He<br />

confirmed that the preceding aircraft was still<br />

on runway. (In later discussions, it emerged that<br />

he was teaching his pupil how to taxy – to date<br />

I still don’t forgive him). Touching down on the<br />

runway at 180 kmph, I slammed on the brakes,<br />

praying that it should not get any worse and<br />

hoped that I did not suffer a tyre burst/ brake<br />

failure (a common occurrence on this aircraft).<br />

My aircraft had slowed down even though I had<br />

shifted to the right lane catering to overtake him<br />

if required. There is no rule as to which side or<br />

how you should overtake another aircraft on<br />

runway – since the instructor is on the right hand<br />

seat, I thought he might notice when I overtook<br />

him.<br />

All’s well that ends well but coming to the<br />

lessons learnt...<br />

<br />

Pushing task is positively anti safety.<br />

Endurance at endurance setting is<br />

different from max settings.<br />

<br />

Adapt to limitations of the aircraft.<br />

Do not teach taxying with an aircraft on<br />

your tail on the runway.<br />

Do not fly an aircraft cleared only for VMC<br />

in IMC.<br />

-Cdr Sunil Chungath<br />

Editor’s Comments :<br />

Though the concept of ‘slow lane’ does exist while<br />

recovering in formations, the procedure is not<br />

usually practised at the ab-initio level, owning to<br />

lesser experience.<br />

The balance between instructional flying and safe<br />

recovery is a crucial but hazy one and must be<br />

discussed continuously. The actions of the first ac<br />

pilot, could have seriously jeopardised the latter’s<br />

safety.<br />
