Redémarrage moteur en vol

[Takumi]

Salut, j'ai besoin de précisions sur la procédure du manuel de vol :

La ligne numéro 5 ; il faut mettre le deuxième moteur au max?
Cette procédure s'applique-t-elle si les 2 moteurs s'éteignent? ( trop gourmand en vol sur le dos :D )

Single Engine Restart
If an engine needs to be restarted while in flight you can either use the APU to restart the engine or perform a windmill air start.
APU Restart. Using the APU to restart an engine is performed as follows:

1. Move the inoperative engine throttle to the OFF position.
2. Observe that the shut down engine ITT value cools down rapidly.
3. Aircraft altitude should be below 20,000 ft MSL and increase airspeed.
4. When below 15,000 ft MSL, move the APU power switch to the START position.
5. Move the still operating throttle to MAX.
6. Set the Engine Operate switch of the affected engine to the MOTOR setting.
7. When affected engine ITT is below 100 °C and altitude below 15,000 ft MSL, restart the affected engine by moving the throttle from OFF to IDLE.
8. Move the Engine Operate switch of the affected engine back to the NORM position.
9. If engine restart is successful, reengage the SAS switches and set engine operate switch back to NORM.
