SYMBOLS, ABBREVIATIONS AND TERMINOLOGY
GENERAL AIRSPEED TERMINOLOGY AND SYMBOLS
KCAS
:
Knots Calibrated Airspeed is indicated airspeed corrected
for position and instrument error and expressed in knots.
Knots calibrated airspeed is equal to KTAS in standard
atmosphere at sea level.
MPH CAS :
Miles per Hour Calibrated Airspeed
KIAS
:
Knots Indicated Airspeed is the speed shown on the
airspeed indicator and expressed in knots.
MPH IAS
:
Miles per Hour Indicated Airspeed
KTAS
:
Knots True Airspeed is the airspeed expressed in knots
relative to undisturbed air which is KCAS corrected for
altitude, temperature and compressibility.
V
A
:
Maneuvering Speed is the maximum speed at which full or
abrupt control movements may be used.
V
FE
:
Maximum Flap Extended Speed is the highest speed
permissible with wing flaps in a prescribed extended position.
V
LE
:
Maximum Landing Gear Extended Speed is the maximum
speed at which an airplane can be safely flown with the
landing gear extended.
V
LO
:
Maximum Landing Gear Operating Speed is the maximum
speed at which the landing gear can be safely extended or
retracted.
V
NE
:
Never Exceed Speed is the speed limit that may not be
exceeded at any time.
V
NO
:
Maximum Structural Cruising Speed is the speed that
should not be exceeded except in smooth air, and then only
with caution.
V
SO
:
Stalling Speed or the minimum steady flight speed at
which the airplane is controllable in the landing configuration.
