FAA: The USA's Federal Aviation Agency, the successor to the Civil Aeronautics Board.

FABRIC: Originally meant "doped" linen or muslin. Today may also refer to polyester weaves.

FAF: Final Approach Fix, a specific position ("fix") from which an instrument approach to landing is begun

FAN: The wide multibladed turbine disk at the front of the inlet of a turbofan engine. The fan both feeds air to the compressor and acts as a kind of propeller.

FAP: Final Approach Point, a specific position on a non-precision instrument approach where the plane is established inbound on the final approach course

FBO: Fixed Base Operator, a business or company located upon an airport that provides various general aviation services such as aircraft refueling, maintenance, parking, rental, flight instruction, charter, ect. Are primarily found at small to regional public use airports.

FCS: Could be either a Fire Control System for the automatic aiming of airborne or shipborne guns, or a Flight Control System.

FE: Flight Engineer. A third crewmember, usually in charge of the various aircraft systems such as hydraulics, electricals, engines and so on.

FEATHER: To turn the blades of a propeller into the wind after an engine failure so as to minimize drag from the engine.

FEET WET: To make a transition from flying over land to flying over ocean.

FINAL APPROACH SEGMENT: On an instrument approach, the segment from the final approach fix to the runway

FINAL: The part of the landing pattern just before the plane lands, where the plane is lined up with the runway

FINGER FOUR: The standard configuration of a flight of four fighters. When seen from above the aircraft formation is reministent of the arrangement of the fingertips of a right hand.

FILE: To file a flight plan, whether on the ground or in the air.

FIRE-AND-FORGET: Any air-to-air missile guidance system design that allows the pilot to turn his attention to other matters once the missile has been launched.

FIVE BY FIVE: I read you five (loudest) by five (clearest), therefore I'm reading you loud and clear.

FIX: A specific geographic position, determined visually or relative to radio navaids

FL: Flight Level, an altitude based on standard instead of actual air pressure; used for high altitude flight (above 18,000'); flight levels correspond to 100 foot increments in altitude

FLAP SCHEDULE: A list of the airspeeds at which flaps should be moved from one setting to the next. Thus one speaks of "flap retraction schedule" and "flap extension schedule".

FLAPERONS: Control surfaces that can be operating synchronously as flaps or differentially for roll control.

FLARE: The nose-up maneuver just prior to touchdown that arrests the aircraft's descent. It is the opposite of takeoff "rotation".

FLYING BANANA: See "mixmaster".

FIRE BOTTLE: A fixed-mount fire extinguisher that can be discharged manually or automatically for purposes of suppressing fire in confined spaces such as engine nacelles, cargo holds, electrical bays, and so on.

FO: First officer, i.e. an airline copilot.

FORM DRAG: The part of an aircraft's overall drag that is attributed to the shapes of the aircrafts's components. Combines with "induced drag" to yield total drag.

FLAT SPIN: A very dangerous and possibly unrecoverable stalled condition in which an aircraft rotates continuously about its yaw axis while descending essentially vertically in an approximately level attitude, with little forward motion.

FLIR: Forward Looking InfraRed, a night vision sensor that is especially sensitive to heat emissions from vehicle engines, people, etc.

FMC: Flight Management Computer; see FMS below.

FMS: Flight Management System, a computer system in large aircraft used to aid in navigation of pre-programmed routes

FPS: Frames per second, a rough measure of Flight Simulator performance

FREEWARE: Software legitimately available at no cost to the user, as opposed to "payware", which bears a price

FS4: Microsoft's Flight Simulator version 4

FS5: Microsoft's Flight Simulator version 5

FS6: Microsoft's Flight Simulator for Windows 95

FS: Flight Simulator, usually Microsoft's

FSACOF: Jargon for the product named "Flight Simulator 2004 -- A Century of Flight".

FSFS: BAO's Flight Simulator Flight Shop (distributed by Apollo)

FSFW95: Microsoft's Flight Simulator for Windows 95

fsOC: The Flight Simulator Open Components association of freeware and payware addon developers.

FS9: Jargon for the product named "Flight Simulator 2004 -- A Century of Flight".

FS98: Microsoft's Flight Simulator 98

FS2000: Microsoft's Flight Simulator 2000, also referred to as FS2K

FS2002: Microsoft's Flight Simulator 2002

FS2004: Microsoft's Flight Simulator 2004: A Century of Flight. Also referred to as ACOF (taken from the "A Century Of Flight") part of the official name on the box. In addition, referred to as FS9 (taken from the folder name where the software is installed).

FSS: Flight Service Station, a facility that provide pilot briefings, enroute communication, NOTAMS, weather and other information

FUEL MANIFOLD: A central fuel tanks flow "switch" that allows fuel to be transferred from one tank to another, or that allows engines to be fed from selected tanks.
