Maximum Continuous Power – The maximum power rating, limited
to emergency or abnormal conditions only, which require maximum
aircraft performance, for example, extreme icing conditions or excessive
downdrafts. This power is developed at the maximum torque limit of 1970
lb.ft., ITT of 790°C, or an
limit of 101.6%, whichever occurs rst.
Maximum Cruise Power – The maximum power approved for cruise;
maximum cruise power is not time limited. This power setting relates to the
power developed at the maximum cruise torque from the Max Torque for
Cruise Chart in “Section 5,” ITT of 740°C or the
limit of 101.6%,
whichever occurs rst.
Maximum Takeoff Power – The maximum power rating, limited to a
maximum of 5 minutes for normal operations. Use of this power setting
should be limited to normal takeoff operations. This power setting is
dened by the limitations of the maximum torque of 1970 ft.lb., 790°C ITT
or the
limit of 101.6%, whichever occurs rst.
– Represents the gas generator (compressor turbine) RPM. 100%
– Represents Propeller RPM and is an indication of the propeller speed in
RPM.
Reverse Thrust – The thrust produced when the propeller blades are rotated
beyond a at pitch and into a reverse angle.
RPM – Revolutions Per Minute.
SHP - Shaft Horsepower – The power available at the propeller shaft.
Torque – A measurement of the rotational force exerted by the engine on the
propeller shaft.
Windmill – Propeller rotation powered by relative airow only.
SHP = Propeller RPM x Foot Pounds of Torque
