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.

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
