Obtained by placing the condition lever in the LO IDLE position.
Is the highest power rating for cruise and is not time limited.
The maximum power available from an engine for use during an emergency
The maximum power available from an engine for continuous normal climb
The maximum power available from an engine for continuous operation in cruise
(with lower TGT limit than normal rated climb power).
Obtained by lifting the power levers and moving them aft of the beta range.
Revolutions Per Minute.
The maximum power available from an engine for takeoff, limited to periods
of five minutes duration.
CONTROL AND INSTRUMENT TERMINOLOGY.
The fuel shut-off lever actuates a valve in the fuel control unit which controls
the flow of fuel at the fuel control outlet and regulates the idle range from LO
The tachometer registers the RPM of the gas generator with 100% representing
a gas generator speed of 37,500 RPM.
Power Lever (Gas
This lever serves to modulate engine power from full reverse thrust to takeoff.
The position for idle represents the lowest recommended level of power for flight
This lever requests the control to maintain RPM at a selected value and, in
Lever (N2 RPM)
the maximum decrease RPM position, feathers the propeller.
This Governor will maintain the selected propeller speed requested by the propeller
The torquemeter system determines the shaft output torque. Torque values are
obtained by tapping into two outlets on the reduction gear case and recording
the differential pressure from the outlets.
Two gages on the instrument panel indicate the temperature between the
compressor and power turbines.
GRAPH AND TABULAR TERMINOLOGY.
Above ground level.
Best Angle of
The best angle-of-climb speed is the airspeed which delivers the greatest gain
of altitude in the shortest possible horizontal distance with gear and flaps up.
Best Rate of Climb
The best rate-of-climb speed is the airspeed which delivers the greatest gain
of altitude in the shortest possible time with gear and flaps up.
