Abbreviations & Terminology
Airspeed Terminology
KCAS
Calibrated Airspeed is the indicated airspeed corrected for position and
instrument error and expressed in knots.
KIAS
Indicated Airspeed is the speed shown on the airspeed indicator and
expressed in knots.
KTAS
True Airspeed is the airspeed expressed in knots relative to undisturbed
air, which is KCAS, corrected for altitude and temperature.
V
A
Design maneuvering speed
V
C
Design cruising speed
V
FE
Maximum Flap Extended Speed is the highest speed permissible with
wing flaps in a prescribed extended position.
V
H
Max Speed in level flight with Max continuous power
V
LO
Lift off speed: is the speed at which the aircraft generally lifts off from the
ground.
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, then only with caution.
V
S
Stalling Speed or minimum steady flight speed flaps retracted
V
S0
Stalling speed or minimum steady flight speed in landing configuration
V
S1
Stalling speed in clean configuration (flap 0°)
V
X
Best Angle-of-Climb Speed is the speed, which results in the greatest gain
of altitude in a given horizontal distance.
V
Y
Best Rate-of-Climb Speed is the speed, which results in the greatest gain
in altitude in a given time.
V
R
Rotation speed: is the speed at which the aircraft rotates about the pitch
axis during takeoff.
Meteorology Terminology
OAT
Outside Air Temperature is the free air static temperature expressed in
degrees Celsius (°C).
T
S
Standard Temperature is 15°C (59
°
F) at sea level pressure altitude and
decreased by 2°C for each 1000 ft of altitude.
H
P
Pressure Altitude is the altitude read from an altimeter when the
barometric subscale has been set to 29.92”
Engine Power Terminology
RPM
Revolutions Per Minute: is the number of revolutions per minute of the
propeller, multiplied by 2.4286 yields engine RPM.
