1.5 DEFINITIONS AND ABBREVIATIONS

(a) Airspeeds
CAS: Calibrated Airspeed. Indicated airspeed, corrected for installation and
instrument errors. CAS equals TAS at standard atmospheric conditions at MSL.
IAS: Indicated Airspeed as shown on an airspeed indicator.
KCAS: CAS in knots.
KIAS: IAS in knots.
TAS: True Airspeed. The speed of the airplane relative to the air. TAS is CAS
corrected for errors due to altitude and temperature.
v : Maneuvering Speed. Full or abrupt control surface movement is not permissible
A
above this speed.
v : Max. Flaps Extended Speed. This speed must not be exceeded with the given
FE
flap setting.
v : Never Exceed Speed in smooth air. This speed must not be exceeded in any
NE
operation.
v Maximum Structural Cruising Speed. This speed may be exceeded only in
NO
smooth air, and then only with caution.
v : Stalling Speed, or the minimum continuous speed at which the airplane is still
S
controllable in the given configuration.
v : Stalling Speed, or the minimum continuous speed at which the airplane is still
S0
controllable in the landing configuration.
v : Best Angle-of-Climb Speed.
x
v : Best Rate-of-Climb Speed.
