GENERAL AIRSPEED TERMINOLOGY
AND SYMBOLS
CAS
Calibrated A irspeed is the indicated speed
of an airplane, corrected for position and
instrument error. Calibrated airspeed is equal
to true airspeed in standard atmosphere at
sea level.
GS Ground Speed is the speed of an airplane
relative to the ground.
IAS lndicated Airspeed is the speed of an airplane
as shown on the airspeed indicator when
corrected for instrument error. IAS values
published in this handbook assume zero
instrument error.
KCAS Calibrated Airspeed expressed in " knots".
KIAS
lndicated Airspeed expressed in " knots " .
TAS True Airspeed is the airspeed of an airplane
relative to undisturbed air which is the CAS
corrected for altitude, temperature, and
compressibility.
VA
Maneuvering Speed is the maximum speed
at which application of full available aero-
dynamic control will not overstress the
airplane.

speed permissible with wing flaps in a pre-
