TM 55-1510-219-MTF
determined by reference to Maximum Cruise Speed/ Engine
Acceptance chart (figure 6). Cruise torque must be attainable without
exceeding the 730°C TGT limit to be acceptable. Indicated fuel flow
must be within ± 10 and -25 pounds per hour of chart value. Pilot's and
copilot's airspeed indicators will agree within ±4 KIAS.
