F
FAA - Federal Aviation Administration.
FADEC - Full authority digital engine control.
Fairing - A section of aircraft surface, or an attached structure, designed to reduce drag. For example, the contoured sheet metal where wing meets fuselage.
FAR - Federal Aviation Regulations (U.S.)
FAR 36 Noise Levels - In order to meet FAR 36 Stage 3 requirements, the maximum noise level permitted is:
*Take Off 89.0 EPNdB
*Sideline 94.0
*Approach 98.0
FDE - Fault detection and exclusion (GPS)
FDR - Flight Data Recorder
FDS - Flight Director System
FFON - Flight Phone
Flare - The point where an airplane floats above the runway just before touchdown.
Flight Data Recorder - Electronic device that records aircraft maneuvers. Used in accident investigations.
Flight Phone - Air-to-ground telephone system.
FM - Frequency modulation.
FMCS - Flight management computer system.
FMS - Flight Management System
FOG - Fiber-optic gyro.
Forward elevator - A control surface used to tilt an airplane up or down and mounted on the front rather than the rear of an airplane.
Full De-ice - Complete anti - and/or de-ice equipment installed on wings, tail, props, and windsheild.
Full Panel - All gyros necessary for instrument flight.

G
Galley - On-board meal service equipment.
Gas discharge - A type of luminescent digital display.
GCR - Ground clutter rejection.
GE - General Electric. They make aircraft engines.
GLU - GNSS landing unit. Provides precision GPS guidance to the runway in Category III operations.
GNSS - Global navigation satellite system.
Gold Crown - Trade name owned by King Radio Corp.
GPADIRS - Global positioning, air data, inertial reference system.
GPS - Global positioning system.
GPWs - Ground Proximity Warning System
Ground Air - A/C unit to cool aircraft while on the ground.
GS - Groundspeed.
G/S - Glide slope reciver and indicator.
GTWO - Gross Take off Weight

H
HF - High Frequency radio equipment.
HF COM - High Frequency Communication.
HIRF - High intensity radiated field.
HP - Horsepower.

Hz or Hertz - Cycles per second, used to describe radio frequencies; usually with the prefix k for kilo (one thousand), M for mega (one million) or G for giga (one billion).

I
IAC - Integrated avionics computer. Central processor of a Honeywell integrated cockpit system.
IAPS - Integrated avionics processing system. Central processor of a colins integrated cockpit system.
IFR - Instrument Flight Rules. An Instrument Rating is further training after a Pilot's license to allow pilots to fly in bad weather. The pilot has been trained to not merely fly by instruments alone, but also to understand the Air Traffic Control system, because an IFR flight is continuously monitored by ATC, radar, flight following, and a dozen other agencies.
ILS - Instrument Landing System.
In-line engine - An engine in which the cylinders are mounted in a straight line or else in two, connected at an angle.
INS - Inertial Naviagation System

IVSI - Instantaneous vertical speed indicator.

J
Jet Prop - Describes aircraft using turbine engines to drive propellers.

K
King - King Radio Corp. (Avionics mfgr.)
Known Icing - FAA certified for flight into icing conditions.

L
Laser IRS - An inertial reference system deriving angular rate information by measuring Doppler shift between two contra-rotating light beams.
Lateral control - The ability to make an airplane roll, or turn around its long axis, according to its pilot's wishes.
L-band - A radio frequency between 890 and 1550 MHz.
LCD or LC - Liquid-crystal display.
Leading and trailing edges- The foremost and rearmost edges of a wing.
LED - Light-emitting diode.
LMB - Light marker beacon.
LNAV - Lateral navigation guidance.
LOC - Localizer receiver and indicator.
Looks per minute - Scanning or sweep rate of a wather radar antenna.
LOP - Line of position.
