TAS
— True Airspeed is the airspeed of an airplane relative to
undisturbed air, which is the CAS corrected for altitude,
temperature and compressibility.
Va
—
Maneuvering Speed is the maximum speed at which the abrupt
application of full available aerodynamic control will not over-stress
the airplane.
Vfe
— Maximum Flap Extended Speed is the highest speed permissible
with wing flaps in a prescribed extended position.
Vne
— Never Exceed Speed is the speed limit that may not be
exceeded at any time.
Vno
— Maximum Structural Cruising Speed is the speed that should
not be exceeded except in smooth air and then only with caution.
Vs
— Stalling Speed or the minimum steady flight speed at which the
airplane can maintain altitude.
Vso
— Stalling Speed or the minimum steady flight speed in the landing
configuration (i.e., full flaps).
Vx
— Best Angle-of-Climb Speed is the airspeed that delivers the
greatest gain of altitude in the shortest possible horizontal distance.
Vy
— Best Rate-of-Climb Speed is the airspeed that delivers the
greatest gain in altitude in the shortest possible time.
