Is it standard Operating Proceedure to do an APU start on BA in the air?
Thought they normally did it on taxi in? Unless you have a problem that is
The Apu door is open on the tail!!
The APU will Autostart for the following:
- Aircraft in Air
- Loss of power from BOTH transfer buses
Not sure about the pictures of the RAT, it could of been dislodged post impact as there was lots of big bits falling off in that area
But that can be deployed manually or Auto
In Auto it will deploy for the Following
- Aircraft in Air
- Loss of power from BOTH Transfer Buses
These are both Gotchas for maintenance, if you jack the aircraft and you remove the power you get all sorts happening in the hangar if you dont pull CBs or guard the Rat area.!!!
So loss of Both main AC power sources then?...Both IDGs...or engines?
Cannaee get ane more power Capt'n...Never mind Scotty we are goin for a landin!!
If you aint got Airspeed theres only AoA...more of it..till Stall..Re: G-ARPI Trident in Staines
