CHORD LINE  look up translate image
A line drawn from the leading edge of the wing to the trailing edge
CONTRAIL  look up translate image
Streaks of condensed water vapor created in the air by aircraft flying at high altitudes
CONTROL INPUTS  look up translate image
The controlling influences a pilot exerts on an aircraft's control surfaces

Flying without the aid of engine power
DIHEDRAL  look up translate image
The upward angle of the airplane's wings with respect to the horizontal
DIRECTIONAL STABILITY  look up translate image
The tendency of an aircraft to keep flying the direction it's pointed
DIRTY; DIRTY UP  look up translate image
Extension of gear, hook, flaps, etc. for slow speed flight or landing

A condition of being threatened by serious and/or imminent danger and of requiring immediate assistance
DITCH  look up translate image
To land safely somewhere other than a runway
DIVERT  look up translate image
To change from a scheduled landing base to an alternate airfield
DRAG  look up translate image
Force created by an airfoil moving through atmosphere, opposite to the direction of motion
ETA  look up translate image
Estimated Time of Arrival. The time the flight is estimated to arrive at its destination
EXPEDITE  look up translate image
Used when prompt compliance is required to avoid the development of an imminent situation
FARS  look up translate image
Federal Aviation Regulations. The laws under which airmen in the US fly
FBO (FIXED BASE OPERATOR)  look up translate image
The small but important building near the ramp and runways of a small airport, from which airfield activity is coordinated
FINAL  look up translate image
Used to mean an aircraft is on proper heading, descent rate, airspeed, and altitude during runway approach prior to landing, or to a target prior to weapons release
FLARE  look up translate image
The maneuver performed moments before landing in which the nose of an aircraft is pitched up to minimize the touchdown descent rate. Also ensures that the main landing gear touches before the nose wheel in tricycle geared aircraft
FPM  look up translate image
Feet Per Minute. Unit of measure, used for ROC (Rate of Descent) or sometimes speed
GROUND SPEED  look up translate image
The speed of an aircraft relative to the surface of the earth
IAS (INDICATED AIRSPEED)  look up translate image
The speed of an aircraft as shown on its pitot static airspeed indicator calibrated to reflect standard atmosphere adiabatic compressible flow at sea level uncorrected for airspeed system errors.
IFR  look up translate image
Instrument Flight Rules. Weather conditions too poor for flight under VFR. Instrument Navigation Equipment and IR (Instrument Rating) by pilot required to fly under these conditions
ILS  look up translate image
Intrument Landing System. A precision instrument approach system, generally used to land at fields experiencing weather
INDICATED ALTITUDE  look up translate image
The altitude as shown by an altimeter
INS (INERTIAL NAVIGATION SYSTEM)  look up translate image
A totally self-contained system which requires no information from outside references. Provides aircraft position and navigation information in response to signals resulting from inertial effects on components within the system
JET STREAM  look up translate image
A migrating stream of high-speed winds present at high altitudes
KIAS  look up translate image
Knots Indicated Air Speed. IAS, in knots.
KNOT  look up translate image

KTAS  look up translate image
Knots True Air Speed. TAS, in knots
LATERAL AXIS  look up translate image
The axis about which an aircraft pitches, extending out along each wing.
LATERAL STABILITY  look up translate image
Stability about an airplane's longitudinal (nose to tail) axis
LIFT  look up translate image
Force created by an airfoil moving through atmosphere, perpendicular to the direction of motion
LOAD FACTOR  look up translate image
The ratio of a specified load to the total weight of the aircraft. The specified load is expressed in terms of any of the following: aerodynamic forces, inertia forces, or ground or water reactions
LOGBOOK  look up translate image
A pilot's record of his flying achievements, including flight time, takeoffs, landings, and maneuvers mastered
