Boeing 767 Hydraulic/Electrical Question
Hiya, I am looking for some clarification with the 767.
I understand that the ADP pump supplies hydraulic power to the center system as long as there is bleed air pressure available. This hydraulic pressure then in turn provides pressure to drive the HDG which provides electrical power to the system. The RAT only provides hydraulic pressure to the flight controls. My question is, suppose you are having a real lousy day and you lose both engines and have no apu. Since you no longer have bleed air, you now have no hydraulics and the only source of electrics other is your battery. You only have flight controls. Is this correct?
