Does the ram air turbine not retract when the APU comes online? Seems like you'd want to not have that drag once it wasn't needed anymore .. especially because you don't have any thrust.

My initial thought would be that you dont want to risk retracting it in case there would be any problem with the apu. The increased drag from the RAT is barely existent

@@zachansen8293 having the drag from the two dead engines is far worse than the small ram turbine. ETOPS regulates how far your are can fly with a single engine failure. They dont take dual engine failures in consideration. If both engines die over the ocean you are basically screwed.

RAT cannot be retracted once it is deployed. Maintenance has to retract it on the ground.

@@iamjesper The drag of the engines is irrelevant to the drag of the RAT. It doesn't matter if something else is more, the question is the impact of the RAT. but as someone else already said there is apparently no retraction mechanism.

Very cemplex and sopfisticated system.

At 5:18 it is not a propeller, its a turbine. Yes it looks like a propeller but it is not.

hello sir one confusion is there please reply... after the engine starts the bevel gear is attached to the main shaft is removed from there or not.

It will continue to run and drive the gearbox of the engine.

Can you make a video on how oxygen generation system and emergency oxygen generation system works

I'll cover them in the upcoming air conditioning system series.

5:18 the ram air TURBINE is a TURBINE not a propeller!
