flight crew
flight crew Personnel assigned to operate aircraft.
flight cycle Sequence of operations and conditions,
different for airframe, propulsion and each system or
equipment item, which together make up one flight.
flight data recorder See flight recorder.
flight deck 1 Compartment in large aircraft occupied by
flight crew.
2 Upper deck of aircraft carrier.
flight department Part of large company responsible for
providing air travel [executive aircraft or airline] whenever
needed.
flight despatcher See despatcher.
flight director 1 Flight instrument generally similar to
attitude director giving information on pitch, roll and
related parameters.
2 Panel controller for autopilot.
3 Most senior member of large wide-body cabin crew.
flight-director attitude indicator Manned-spacecraft
display indicating attitude, attitude error and rate of
pitch, yaw and roll.
flight duty period See crew duty time.
flight dynamics General subject of motion of aerodyne
and laws which govern it.
flight effects Changes in relationships as an aircraft
accelerates from rest to cruising speed, nortably velocity
shear at jet boundary.
flight engineer Aircrew member responsible for powerplant,
systems and fuel management, and also sometimes
for supervising turnround servicing. Today rare except R
and military.
flight envelope 1 See gust envelope.
2 Curves of speed plotted against altitude or other variable
defining performance limits and conditions within
which equipment must work. Commonly assessed at three
levels: operational *, for normal flying; service *, defined
by service ceiling, normal limiting IAS etc.; and permissibale
*, including limiting manoeuvres.
flight envelope monitoring AFCS function providing
computation of V MIN , V MAX and angle-of-attack limits.
flight-envelope protection System in FBW [Airbus]
aircraft which cannot normally be over-ridden by [eg
hijacker] pilot which automatically commands climb or
turn to avoid hitting an obstacle.
flight fine pitch Finest propeller blade angle available in
flight. Weight on wheels may remove * stop, enabling
drag to be increased.
flight flutter kit Installation, together with instrumentation,
of ‘bonkers’ or other devices to induce flutter in
flight-test aircraft.
flight-following Maintaining contact with specified
aircraft to determine en route progress.
flight idle Lowest engine speed available in flight, set by
** stop, mechanical limit released to ground-idle position
at touchdown.
flight indicator Instrument combining lateral inclinometer,
fore-and-aft inclinometer and turn indicator
(obs.).
flight indicator board Display in airport terminal
showing arrivals and departures of airline flights.
flight information centre Unit established to provide
flight information service and alerting service.
flight information region, FIR Airspace of defined
dimensions within which flight information and alerting
services are provided by air traffic control centre.
flightpath deviation
flight information service Service giving advice and
information useful for safe and efficient conduct of
flights. In good weather provides listening watch only.
flight inspection 1 By specially equipped aircraft, of
accuracy of navaids.
2 Periodic examination of flight crew and ATC
controllers.
flight instruments Those used by pilot(s) to fly aircraft,
esp. those providing basic information on flight attitude,
speed and trajectory.
flight integrity Close relationship between two friendly
combat aircraft manoeuvring for mutual support.
flight jacket Half-length zipped jacket of nylon with
polyester filling, usually dark blue or olive/sage green. A
traditional type is goatskin or fleece-lined sheepskin.
flight level, FL Level of surface of constant atmospheric
pressure related to datum of 1013.25 mb (29.92 in
mercury), expressed in hundreds of feet; thus FL 255 indicates
25,500 ft (see QFE, QNH).
flight-line 1 Ramp area of airfield, where aircraft are
parked and serviced.
2 In reconnaissance mission, prescribed ground path
across targets.
flight Mach number Free-stream Mach number
measured in flight.
flight management system Automatic computercontrolled
system with autothrottle, possible Mach-hold,
and complete control of navigation, including SIDs and
STARs. Offers “menus” for minimum cost, minimum fuel
burn or other objectives. Relieves workload, increases
precision. Hence FMST, * trainer, synthesizes all these
functions.
flight manual Book prepared by aircraft manufacturer
and carried on board, setting out recommended operating
techniques, speeds, power settings, etc, necessary for
flying particular type of aircraft. Known to airlines as
operations manual.
flight mechanic Pre-1935 title of flight engineer.
flight mechanics One of the two components of flight
dynamics, whose role is to establish the right balance
between stability, manoeuvrability and control power.
flight number See flight (7).
flight office On a GA airfield, centre for booking pleasure
flights and carrying out domestic business, but not
concerned with ATC or visiting pilots.
flight panel Accepted definition: panel grouping all
instruments necessary for continued flight without
external references. Preferable: panel grouping available
flight instruments.
flightpath Trajectory of centre of gravity of vehicle
referred to Earth or other fixed reference. In following five
definitions H signifies * in horizontal plane and V in
vertical plane.
flightpath angle Acute angle between flightpath (V) and
local horizontal, shown on FPA display by resolving G/S
and V/S.
flightpath computer See course-line computer (H).
flight-path controller Digital system for Coast Guard
(UK) helicopters comprising Doppler, ‘radalt’, attitude
gyro and accelerometers to control low-altitude hover in
absence of visual reference. Modes include autotransition,
up/down, ability to overfly target.
flightpath deviation Angular or linear difference
between track and course of an aircraft (H).
