B 757 Centre Hyraulic Pumps Unserviceable
In the B 757 with both centre hydraulics pumps unserviceable, the QRH says to put off C1 & C2 electric pumps switches to off.
The inoperative items are the centre autopilot and the Left auto stabilizer trim.
My question is why not deploy the RAT manually and get the centre hydraulic system back on line and have all system functioning normally?
