Symbols, Abbreviations and Terminology

General Airspeed Terminology and Symbols

KCAS Knots Calibrated Airspeed is the indicated airspeed

corrected for position and instrument error. Calibrated

airspeed is equal to true airspeed in standard atmosphere at

sea level.

KIAS Knots Indicated Airspeed is the speed shown on the

airspeed indicator. The IAS values published in this

handbook assume no instrument error.

KTAS Knots True Airspeed is the airspeed expressed in knots

relative to undisturbed air which is KCAS corrected for

altitude and temperature.

VGBest Glide Speed is the speed at which the greatest flight

distance is attained per unit of altitude lost with power off.

VOOperating Maneuvering Speed is the maximum speed at

which application of full control movement will not overstress

the airplane.

VFE Maximum Flap Extended Speed is the highest speed

permissible with wing flaps in a prescribed extended position.

VNO Maximum Structural Cruising Speed is the speed that

should not be exceeded except in smooth air, and then only

with caution.

VNE Never Exceed Speed is the speed that may not be exceeded

at any time.

VPD Maximum Demonstrated Parachute Deployment Speed is

the maximum speed at which parachute deployment has

been demonstrated.

VSStalling Speed is minimum steady flight speed at which the

aircraft is controllable.

VS50% Stalling Speed is minimum steady flight speed at which the

aircraft is controllable with 50% flaps.
