General Airspeed Terminology
CAS
Calibrated Airspeed is the indicated airspeed of the aircraft,
corrected for position and instrument error. At sea level and
standard atmosphere, calibrated airspeed is equal to true
airspeed.
KCAS
Knots Calibrated Airspeed is calibrated airspeed expressed
in knots.
IAS
Indicated Airspeed is the uncorrected airspeed of an aircraft.
KIAS
Knots Indicated Airspeed is indicated airspeed expressed in
knots.
TAS
True Airspeed is the airspeed of an aircraft relative to undis-
turbed air which is CAS corrected for altitude, temperature,
and compressibility.
KTAS
Knots True Airspeed is true airspeed expressed in knots.
V
H
Maximum Speed in Level Flight with maximum continuous
power (corrected for sea level standard conditions).
V
O
Operating Maneuvering Speed is the speed above which full
application of any single flight control may generate a load
greater than the aircraft’s structural limitations.
V
S
Stalling Speed or the minimum steady flight speed at which
the airplane is controllable with flaps retracted (clean).
