Take-off
Maximum Torque for all runways is 100% (ITT not exceeding 780 °C).
Climb
After achieving steady climb speed, with the aircraft in clean configuration,
torque shall not exceed 100% (ITT not exceeding 720 °C).
Cruise
Cruise propeller RPM setting is 1700 RPM and Ng not exceeding 98.4 %.
Maximum cruise ITT shall be 720 degrees. If the maximum cruise settings as
per the AFM should cause the ITT to exceed 720 degrees, power setting shall
be reduced to comply with AFM limitations.
Descent
Throughout descent the TCL should be reduced so as not to exceed 720 °C
ITT and 182 KIAS to prevent an overspeed. If the aircraft encounters
moderate or stronger turbulence the aircraft shall be flown at or below the
maneuvering speed appropriate for the weight.
One Engine inop
With one engine inoperative, maximum continuous torque is 100% (ITT not
exceeding 780 °C).
