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.
KIAS
Knots Indicated Airspeed is the airspeed shown on the airspeed indicator
and expressed in knots.
KTAS
Knots True Airspeed is the airspeed expressed in knots relative to the
undisturbed air. This is KCAS corrected for altitude and temperature.
Va
Maneuvering Speed is the maximum speed which you may use abrupt
control travel.
Vfe
Maximum Flap Extended Speed is the highest speed permissible with
flaps extended.
Vle
Maximum Landing Gear Extended Speed is the highest speed
permissible with landing gear extended
Vlo
Maximum Landing Gear Operating Speed is the maximum speed at
which the gear position may be changed.
V
NO
Maximum Structural Cruising Speed is the speed that should not be
exceeded except in smooth air, then only with caution.
V
NE
Never Exceed Speed is the speed limit that may not be exceeded at any
time.
Vs
Stalling Speed or the minimum steady flight speed at which the airplane
is controllable in cruise configuration.
Vso
Stalling Speed or the minimum steady flight speed at which the airplane
is controllable in the landing configuration at the most forward center of
gravity.
Vx
Best Angle of Climb Speed is the speed that results in the greatest gain of
altitude in a given horizontal distance. Operation with all engines
Vy
Best Rate of Climb Speed is the speed that results in the greatest gain of
altitude in a given time.
Vxse
Best Angle of Climb Speed on Single Engine is the speed that results in
the greatest gain of altitude in a given horizontal distance. Operation with
one engine only. Failed engine is feathered.
Vyse
Best Rate of Climb Speed on Single Engine is the speed that results in the
greatest gain of altitude in a given time with one engine only. Failed engine
is feathered.
Vmc
Minimum Single Engine Control Speed the minimum flight speed at which it is
possible to retain control of the aeroplane and maintain straight flight, through
the use of maximum rudder deflection and not more than 5
0
of bank, following
sudden failure of the critical engine.
Vmc is generally determined under the following conditions:
