General airspeed terminology and symbols
IAS
Indicated Airspeed.
KCAS
Calibrated Airspeed, being the indicated airspeed corrected for
position and instrument error, expressed in knots.
KIAS
Indicated Airspeed, being the speed shown on the airspeed
indicator, expressed in knots.
KTAS
True Airspeed, being the airspeed, expressed in knots, relative to
undisturbed air, and which is KCAS corrected for altitude and
temperature.
TAS
True Airspeed.
V
A
Maneuvering speed.
V
BG
Best Glide Speed, being the speed (at MAUW) which results in the
greatest gliding distance over the ground.
V
FE
Maximum Flap Extended Speed, being the highest speed
permissible with wing flaps deployed.
V
H
Maximum Speed in level flight at maximum continuous power.
V
LOF
Lift-off Speed, being the speed at which the aircraft generally lifts
off from the ground during take-off.
V
NE
Never Exceed Speed, being the speed that may not be exceeded at
any time.
V
NO
Maximum Structural Cruising Speed, being the speed that should
not be exceeded, except in smooth air, and then only with caution.
V
REF
Indicated airspeed at 15 m (50 ft) above threshold, which is not less
than 1.3V
so
.
V
ROT
Rotation Speed, being the speed at which the aircraft should be
rotated about the pitch axis during take-off (i.e. the speed at which
the nose wheel is lifted of the ground).
V
S
Stall Speed, maximum weight, engine idling, flaps fully retracted.
V
SO
Stall Speed in landing configuration (flaps fully extended), MAUW,
engine idling.
V
X
Best Angle of Climb Speed, being the speed (at MAUW, flaps fully
retracted) which results in the greatest altitude gain over a given
horizontal distance (i.e. highest climb angle).
