flightpath recorder
flightpath recorder Instrument for recording angle of
flightpath (V) to horizontal.
flightpath sight In HUD, direct aiming point showing
distant point through which aircraft will pass (V, H).
flightpath vector Prediction of future flightpath which
replaces traditional flight director in advanced EFIS,
especially to protect against windshear.
flight plan 1 Specified information relating to whole or
portion of intended flight (2); filed orally or in writing
with air traffic control facility.
2 Common working document, both in spacecraft and
at all ground stations during manned or unmanned space
flight. Separate ** issued for lunar or planetary surface
operations.
flight-plan correlation Means of identifying aircraft by
association with known flight plans.
flight platform See helipad.
flight profile Plot of complete flight (2) in vertical plane,
usually altitude plotted against track distance.
flight process board In ATC centre, displays all current
FP strips.
flight-progress strip ATC aide-memoire: paper strip
typically 25 mm × 200 mm, coloured for traffic direction,
giving one flight’s c/s, FL, ETA as amended; slid into FP
board until passed to colleague at handover.
flight-proximity demonstration Flight in which a receiver
aircraft formates behind a tanker even though neither
may be equipped [yet] to supply or receive fuel.
flight rating test One in which member of flight crew
demonstrates ability to comply with requirements of
particular licence or rating.
flight-readiness firing Short-duration test of in-service
space launcher, or other rocket vehicle, on launcher.
flight recorder Device for automatically recording information
on aircraft operation. Main type is flight data
recorder (FDR), also colloquially called crash recorder or
‘black box’, although invariably bright orange. Records
50 or more parameters, including following mandatory
channels: altitude, airspeed, vertical acceleration,
heading, elapsed time at 1s intervals (UK also requires
pitch, and usually control-surface positions, high-lift
surface positions, engine speeds and flight-crew speech are
also included). Such recorders are designed to survive
crash accelerations, impacts, crushing and fire, and often
carry underwater transponders or beacons. Normally
recording medium, eg multi-track steel tape, is recycled
every 25 h. Cockpit voice recorder (CVR) stores all speech
on flight deck or cockpit, including intercom and radio.
Maintenance recorders, eg AIDS, are linked by serial data
highways to hundreds of transducers and other inputs
recording many kinds of information (temperatures,
vibrations, pressures and electronic parameters) to yield
advance information of impending fault conditions or
failures and improve system operation and economy.
Highways lead to various logic and acquisition units,
some for quick-look and others long-term; separate
highway to protected FDR often provided.
flight reference card Carried in cockpit to provide quick
detailed list of vital actions in event of all system failures
or emergencies commonly encountered, with recommendations,
suggestions and prohibitions.
flight regime State of being airborne, governing many
systems and modes unavailable on ground.
flight time
flight release certificate Issued for aircraft with Permit
to Fly (UK CAA).
flights Always plural, the offices [usually on the air side
of hangars] and nearby aircraft parking areas of
operational units on a permanent RAF station (becoming
archaic usage).
flight-safety information management system Proposed
unclassified database of accidents, incidents and malfunctions
reported by participating air forces to improve
safety of military aircraft.
flight schedule monitor Shared by FAA and user
community, is the decision-making tool that forms basis
of current flight information and air-traffic demand at
each airport.
flight service station Facility providing flight assistance
service (FAA).
flight shed Traditional British term for hangar in which
prototypes are completed and readied for flight and
subsequently are kept. Not normally associated with
series production.
flight simulator Electronic device that can simulate
entire flight characteristics of particular type of aircraft,
with faithful reproduction of flight deck; used to test and
check out flight crews, esp. in coping with emergencies,
and (military) in completing combat missions according
to role; or as design and engineering tool during aircraft
development.
flight sister Female nursing officer trained for aeromedical
duties.
flight space Space above and beyond Earth available for
atmospheric or space flight.
Flight Standards District Office Handles all matters
within assigned geographic area (FAA).
flight station 1 Flight crew position away from flight
deck.
2 Base for marine aircraft (WW1).
flight status Indication of whether a given aircraft
requires special handling by air traffic services.
flightstick The inceptor of an entertainment or educational
simulator; not normally in an aircraft.
flight strip 1 Auxiliary airfield on private property,
farmland or adjacent to highway.
2 See flight progress strip.
flight structural mode excitation Allows pilot to
command deterministic signals, such as swept-frequency
sine waves, from FCC to excite all aircraft’s flexural
modes.
flight suit One-piece overall garment with various
pockets, zips and velcros.
flight supplement Added to price of airline ticket to
cover such factors as additional fuel burn and airport
time-slot charges.
flight surgeon Physician (invariably not surgeon)
trained in aeromedical practice whose primary duty is
medical examination and care of aircrew on ground.
flight test 1 Test of vehicle by actual flight to achieve
specific objectives.
2 Test of component mounted on or in carrier vehicle
to subject it to conditions of flight.
3 Flight rating test.
flight test vehicle Special aircraft, missile or other vehicle
for conduct of flight tests to explore either its own capabilities
or those of equipment or component parts.
flight time 1 Elapsed time from moment aircraft first
