I was just wondering which aircraft have the emergency propeller which comes out when engines cut out and it works like a generator, hydraulics, etc ???
I know of a few but can anyone list all of them and tell me if there is any reference on it? Thanks

I believe that all commercial jets have this ability, if they depend on hydraulic boost for control movements. While an APU could also do the job, the APUs on most aircraft cannot be operated above a certain speed and altitude, due to the location of the intake and exhaust ports. I expect that (unless the APU worked off of the same damaged fuel feed) the APU would have been operating during the last few minutes of the Air Transat's flight, and would have been providing power for the controls and other systems.

The RAT helped save the Air Transat Airbus that skidded into the Azores. There was so little eletrical power that the cabin public address system didn't work and the cabin crew chief had to shout out ditching orders.
