Knots Calibrated Airspeed
is indicated airspeed corrected
for position and instrument error and expressed in knots.
Knots calibrated airspeed is equal to KT AS in standard
atmosphere at sea level.
Knots Indicated Airspeed
is the speed shown on the
airspeed indicator and expressed in knots.
Knots True Airspeed
is the airspeed expressed in knots
relative to undisturbed air which is KCAS corrected for
altitude and temperature.
Manuevering Speed
is the maximum speed at which you
may use abrupt control travel.
Maximum Flap Extended Speed
is the highest speed
permissible with wing flaps in a prescribed extended
position.
Maximum Structural Cruising Speed
is the speed that
should not be exceeded except in smooth air, then only with
caution.
Never Exceed Speed
is the speed limit that may not be
exceeded at any time.
Stalling Speed or the minimum steady flight speed
at
which the airplane is controllable.
Stalling Speed or the minimum steady flight speed
at
which the airplane is controllable in the landing configu
ration at the most forward center of gravity.
Best Angle-of-Climb Speed
is the speed which results in
the greatest gain of altitude in a given horizontal distance.
Best Rate-of-Climb Speed
is the speed which results in the
greatest gain in altitude in a given time.
