BACKTAXI: To taxi on the active runway in the direction opposite to landing aircraft, usually to position the aircraft for takeoff at an airport with no taxiways

BALL: Jargon for the sideslip indicator ball element of a turn-and-bank indicator instrument.

BAO: The Bruce Artwick Organization

BARBER POLE: The striped pointer on an airspeed indicator that indicates the airspeed at which supersonic shock waves begin to develop over the control surfaces, adversely affecting aircraft controllability.

BARO: Jargon for the barometer setting knob on an altimeter. Also refers to the window in which the resulting barometric pressure setting may be read.

BASE: The base leg is the part of the landing traffic pattern where the plane flies at a 90 degree angle to that of the landing runway

BDA: Bomb Damage Assessment.

BEARING: The horizontal direction to or from any point, usually measured clockwise from north

BETA: The range of reverse thrust available from a turboprop engine. This is achieved by reversing the sense of propeller pitch.

BGL FILE: A file containing statements in the BAO Graphics Language, the notation in which FS scenery is developed and expressed. Often referred to simply as a ".bgl".

BLADE STALL: A phenomenon in which a helicopter is moving so fast that its retreating rotor blades have insufficient airspeed to generate lift. Sometimes called "retreating blade stall".

BLISTER: Any dome-type protrusion from an aircraft fuselage or wing that houses equipment or people.

BLOWDOWN LIMIT: The airspeed above which a given hydraulically-operated control surface (typically spoilers) has insufficient power to deflect into the relative wind.

BOOST: Depending on the context, may refer to either hydraulic control surface actuators or to a piston engine supercharger.

BMP FILE: Abbreviation of "bit map" file, one of many industry-standard image file formats, often referred to simply as a "bmp". Bmp's are used for many different purposes in the development of addons for FS, notably in the artwork for gauges and panels.

BOGIE: Any landing gear wheels component featuring multiple axles. Also refers to a suspected enemy aircraft, as in "Four bogies at one o'clock high."

BOMB RUN: Also called "bombing run", the straight line ground track from the IP to the point of bomb release. See "IP".

BOUNDARY LAYER: The layer of stagnant air that adheres to the surfaces of an aircraft in flight.

BORESIGHT: To aim at a target at such a close range that that the target need not be led, and that bullet drop need not be considered. Equivalent to "point blank" aim.

BOUNDARY LAYER: See "stagnation layer".

BREAK: A naval aviation approach maneuver in which the aircraft is turned continuously and sharply from the downwind leg of the approach to final, slowing the aircraft. Also means any sharp turn by a military aircraft during crusing flight.

BURBLE: Turbulent airflow over the wings causing airframe buffeting that sets in as a stalled condition is approached.

BURNER CAN: One of the several combustion chambers of an axial flow turbojet engine.

BYPASS RATIO: Turbofan engine jargon for the ratio of the mass flow of air accelerated around the engine nacelle by the fan to the mass flow of air passing into the engine itself.
