Clearing Turns during Climbs<br />

You are especially vulnerable to mid-air collisions during a climb, the reason being that forward visibility is<br />

obscured by the engine cowling. For this reason, once the aircraft departs from the circuit (climbs through 1000’<br />

AGL), you should begin a series of gentle turns, left and right, so that the blind spot is cleared. To do this, use 15<br />

of bank, and turn to a heading approximately 30 (to turn further serves no purpose, and turning to a lesser heading<br />

will not clear the entire blind spot. To keep on track, the second clearing turn should be done in the opposite<br />

direction. During a climb, a clearing turn should be performed approximately every 30 seconds. While you are<br />

encouraged to turn frequently during a climb, do so smoothly and gently.<br />

For the first 1000’ of the departure from a runway, a clearing turn cannot be performed (unless you feel traffic<br />

circumstances warrant it), so before you apply power for takeoff, scan the departure end of the runway for potential<br />

traffic hazards—if you see one during the initial climb, manoeuvre to protect your safety.<br />

BIRD STRIKES<br />

Langley Flying School students are prohibited from conducting a takeoff or landing when birds are present on the<br />

runway (see P. 34 regarding <strong>LANGLEY</strong> <strong>FLYING</strong> <strong>SCHOOL</strong> FLIGHT RULES AND SAFETY<br />

PRECAUTIONSError! Bookmark not defined.). Here are some facts related to bird strikes that are worthy of<br />

remembering:<br />

1) Since 1912, 200 deaths have resulted from bird strikes on aircraft.<br />

2) The greatest risk is in flight below 2,500’ where 99% of all bird strikes occur.<br />

3) The faster the aircraft the greater the risk—up to 80-90 KNOTS, birds have time to get out of the way.<br />

4) The greatest risk is during March and April, and during September and October, when bird migration<br />

occurs.<br />

5) If you see birds ahead of you attempt to pass over, rather than under, as birds dive downward when<br />

threatened.<br />

6) Small birds such as Starlings are highly manoeuvrable and can effectively get out of the way; larger birds<br />

such as ducks, geese, or seagulls, present greater risk. 52<br />

7) Never takeoff or land when large birds are on the runway; instead conduct a low pass in an effort to get<br />

them to move on, in the case of landing, or back-track along the runway before taking off.<br />

8) Anticipate that a bird striking the windscreen will penetrate; use the instrument panel as a shield, anticipate<br />

blood and guts, and remember to fly the aircraft.<br />

9) All bird strikes are to be reported; see the RAC Section of the AIM.<br />

52 Remember, that when in close proximity to the ground, very little if any effort should be made to avoid birds—the speed of the aircraft is slow<br />

and the birds will manoeuvre to get out of the way. In contrast, birds are ineffective in avoiding aircraft when they take off from the ground to<br />

the air, and for this reason a landing or takeoff by an aircraft should never be conducted when there is a risk of contact with birds on the ground.<br />
