1.11. LIST OF DEFINITIONS AND ABBREVIATIONS
1.11.1. Speed
AGL: Above Ground Level
CAS: Calibrated airspeed; Indicated speed corrected for installation and instrument
errors. CAS is equal to TAS at standard atmospheric conditions at MSL.
KCAS: CAS in knots.
IAS: Indicated airspeed as shown on the airspeed indicator.
KIAS: IAS indicated in knots.
GS: Ground Speed. Speed of the airplane relative to the ground.
TAS: True airspeed. Speed of the airplane relative to air. TAS is CAS corrected for
altitude and temperature errors.
v
A
: Maneuvering speed. Maximum speed at which the airplane is not
overstressed at full deflection of control surfaces.
V
FE
: Maximum speed with flaps extended.
v
NE
: Speed which must never be exceeded in any operation.
v
NO
: Maximum structural cruising speed which should only be exceeded in calm
air, and then only with caution.
v
S
: The power-off stall speed with the airplane in its standard configuration.
v
SO
: The power-off stall speed with the airplane in landing configuration.
v
X
: Best angle-of-climb speed.
v
Y
: Bestrate-of-climb speed.
