1.3.2. General Airspeed Terminology and Symbols
CAS Calibrated Airspeed: the indicated speed of an aircraft corrected for position
and instrument error. Calibrated airspeed is equal to true airspeed in standard
atmosphere at sea level.
KCAS Calibrated Airspeed: expressed in knots.
GS Ground Speed: the speed of an aircraft relative to the ground.
IAS Indicated Airspeed: the speed of an aircraft as shown on the airspeed indicator. IAS
values in this manual assume zero instru ment error.
KIAS Indicated Airspeed expressed in knots.
TAS True Air Speed: the airspeed of an aircraft relative to the undisturbed air through
which it passes.
T.O.S.S Take-Off Safety Speed: the airspeed chosen to ensure that adequate control will
exist under all conditions, including turbulence and sudden and complete engine
failure during the climb after take-off. It is the speed required at 50 ft.
V
A
Manoeuvring Speed: the maximum speed at which application of full available
aerodynamic control will not damage or overstress the aircraft.
V
FE
Maximum Flap Extended Speed: the highest speed permissible with wing aps in
a prescribed extended position.
V
NE
Never Exceed Speed: the limiting airspeed that may not be exceeded at any time.
V
NO
Maximum Structural Cruising Speed: the speed that should not be exceeded
except in smooth air and then only with caution.
