1.12. LIST OF DEFINITIONS AND ABBREV ATIONS
1.12.1. Airspeeds
CAS
Calibrated A
irspeed: Indicated airspeed, corrected for
installation and instrument
errors. CAS equals TAS at
standard atmospheric conditions (ISA) at
medium sea
level (
MSL).
GS
Ground Speed
: Speed of the airplane relative to the ground.
IAS
Indicated Airspeed
: Indicated Airspeed as shown on an airspeed indicator.
TAS
True
Airspeed: The speed of the airplane relative to the air.
TAS is CAS corrected
for errors due to altitude and
temperature.
V
FE
Maximum Flaps Extended Speed
: This speed must not be
exceeded with the
given flap setting.
V
LE
Maximum landing gear extended speed
:
This is the maximum speed at which it is
safe to fly with the landing gear extended.
V
LO
Maximum landing gear operating speed
:
This is the maximum speed at which it
is safe to extend or retract the landing gear
.
V
NO
Maximum Structural Cruising Speed
: This speed may be
exceeded only in
smooth air. It corresponds to the top end of the green arc on the airspeed indicator.
V
A
Maneuvering Speed
:
It is the recommended airspeed when flying in turbulent air.
This is the m
aximum speed at which the airplane is
not overstressed at full
deflection of control surfaces. Full or
abrupt control surface movement is not
permissible above this
speed.
V
NE
Never Exceed Speed
: This speed must NOT be exceeded in any operation.
V
S
Stall speed:
The power-off stall speed with
the airplane in its standard
configuration.
V
S0
Stall speed in landing configuration:
The power-
off stall speed with the airplane
in landing
configuration (gear and flaps extended).
V
X
Best Angle
-of-Climb Speed.
V
Y
Best Rate
-of-Climb Speed.
V
r
Rotation Speed
:
This is the speed at which the aircraft rotates about its pitch axis
during take
-off.
V
REF
Reference Speed
.
