Q

Low rpm (2)(7) TIT range

A

410-730C (12)
(12): Max TIT in low rpm shall be limited to 730 degrees C regardless of power lever position, accessory loading, or use of diffuser bleed air to ensure adequate cooling airflow to the turbine.

(2) use of power between GND Start and MAX Reverse in low rpm can cause engine rpm to decay. Contributing causes to higher ambient temp, field elevation, airspeed, accessory load, end bleed are effects on the power available at low rpm. If rpm begins to decay, advance the power lever. If rpm decay continues, shut down the engine
(7) acceleration time from start of rotation to low rpm should not exceed 60secs.
