SYMBOLS, ABBREVIATIONS
AND TERMINOLOGY
The following definitions are of symbols, abbreviations and terminology used throughout the
handbook and those
which may be of added operational
significance
to
the pilot.
(a)
General Airspeed Terminology and Symbols
CAS Calibrated Airspeed means the indicated speed of an aircraft,
corrected for position and instrument
error.
Calibrated airspeed is
equal
to true
airspeed in standard atmosphere at sea level.
KCAS Calibrated Airspeed
expressed in "Knots."
GS Ground Speed is the speed of an airplane relative to the
ground.
IAS Indicated Airspeed
is the speed of an aircraft as shown
on
the
airspeed indicator
when
corrected for instrument
error.
IAS values
published in this handbook
assume zero
instrument
error.
KIAS Indicated Airspeed expressed in "Knots."
M Mach Number is the ratio of true airspeed to the speed of sound.
TAS True Airspeed is the airspeed
of
an airplane relative to undisturbed
air which is the CAS corrected for altitude, temperature
and
compressability.
VA Maneuvering Speed is the maximum speed
at
which application of
full available aerodynamic control will
not
overstress the
airplane.
VFE Maximum Flap Extended Speed is the highest speed permissible
with wing
flaps in
a
prescribed extended
position.
VLE Maximum Landing Gear Extended Speed is the maximum speed at
which an aircraft
can
be safely flown with
the landing gear
extended.
YLO
Maximum Landing Gear Operating Speed is
the maximum
speed at
which the landing gear can
be
safely
extended or retracted.
VNE/MNE
Never Exceed Speed
or
Mach Number 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.
