Nello specifico
The engine start, which is the same for both engines, is as follows: set engine twist grip to a 20-degree setting (as indicated on the grip); press and hold the start switch; wait for the first-limit indicator to move, indicating an increase in TOT; adjust the twist grip to control increase in TOT and keep it within 550 to 650 degrees C. (Max TOT permitted is 785 degrees C for start and 865 degrees transient). Following engine start, tests of the hydraulics, stability augmentation, autopilot, engine fire-extinguishing and other systems follow in logical order.
