KIAS Knots Indicated Airspeed is the speed show on the airspeed
indicator and expressed in knots
KTAS Knots True Airspeed is the airspeed expressed in knots
relative to undisturbed air which is KCAS corrected for altitude
V
A
Maneuvering Speed is the maximum speed at which you many
use abrupt control travel.
V
FE
Maximum Flap Extension Speed is the highest speed
permissible with wing flaps in a prescribed extended position
V
NO
Maximum Structural Cruising Speed is the speed that should
not be exceeded except in smooth air, then only with caution.
V
Ne
Never Exceed Speed is the speed limit that may not be
exceeded at any time.
V
S
Stalling Speed or the minimum steady flight speed at which
the airplane is controllable
V
SO
Stalling Speed or the minimum steady flight speed at which
the airplane is controllable in the landing configuration at the
most forward center of gravity
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 a given time
METEOROLOGICAL TERMINOLOGY
OAT Outside Air Temperature
is the free air static temperature. It is
expressed in either Celsius (formerly Centigrade) or degrees
Fahrenheit.
Standard
Temperature
Standard Temperature is 15°C at sea level pressure altitude
and decreases by 2°C for each 1,000 feet of altitude.
Pressure
Altitude
Pressure Altitude
is the altitude read from an altimeter when
the altimeter’s barometric scale has been set to 29.92 inches
of mercury (1013 mb)
