The region of the power lever control which is aft of the idle stop and forward of
reversing range where blade pitch angle can be changed without a change of gas generator
Is the maximum power approved for normal climb. This power is torque or temperature (ITT)
Obtained by placing the condition lever in the HIGH IDLE position.
Shaft horsepower. That horsepower imparted to the propeller shaft.
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 operation.
Normal Rated Climb
The maximum power available from an engine for continuous normal climb operations.-
Normal Rated Power
The maximum power available from an engine for continuous operation in cruise (with lower ITT
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
CONTROL AND INSTRUMENT TERMINOLOGY.
Condition Lever (Fuel
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 to HIGH]
N1 Tachometer (Gas
The tachometer registers the RPM of the gas generator with 100% representing a gas
generator speed of 37,500 RPM.
Power Lever (Gas Gen-This lever serves to modulate engine power from full reverse thrust to take-off. The
erator N1 DRPM)
position for idle represents the lowest recommended level of power for flight opera-
This lever requests the control to maintain RPM at a selected value and, in the maximum
decrease RPM position, feathers the propeller.
This Governor will maintain the selected propeller speed requested by the propeller control lever.
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
