V
LO
:
Maximum Landing Gear Operating Speed is the maximum speed at
which the landing gear can be safely extended or retracted.
V
MO
:
Maximum Operating Speed is the speed limit that may not be
deliberately exceeded in normal flight operations.
V
R
:
Rotation Speed is the speed at which rotation is initiated during
takeoff to achieve takeoff safety speed at screen height.
V
SO
:
Stalling Speed or the minimum steady flight speed at which the
airplane is controllable in the landing configuration.
V
S1
:
Stalling Speed or the minimum steady flight speed obtained in a
specific configuration.
V
x
:
Best Angle of Climb Speed is the airspeed which delivers the
greatest gain of altitude in the shortest possible horizontal distance.
V
Y
:
Best Rate of Climb Speed is the airspeed which delivers the
greatest gain in altitude in the shortest possible time.
Power terminology
Recovery altitude :
Maximum altitude at which it is possible, in standard temperature, to
maintain a specified power.
Overheated start :
Engine start or attempt to start which causes the interturbine
temperature to be higher than the maximum value permissible
during start.
Flame out
:
Involuntary loss of the combustion chamber flame during operation.
GPU
:
Ground power unit.
Feathering :
Action which reduces the drag of a propeller by positioning blades at
the pitch angle allowing minimal drag.
Maximum Cruise Power :
Power developed corresponding to outside flight level and
temperature conditions - refer to chapter 5 Performance.
Ng
:
Gas generator RPM.
Np
:
Propeller rotation speed.
Reverse
:
Drag produced when the propeller blade setting is negative.
RPM
:
Revolutions per minute.
