Just doing a little thinking , hypothetically
OK so we are in the cruise ( FL 330)over high terrain ( say 15000 ft)
We get EICAS , BLEED OFF ENG L. OK .
Shortly afterwards we loose The Right Engine.
OK I know we have a drift down to consider and off course will have a depressirisation strategy to follow ( while the cabin slowly depressurises). Proceduraly OK.
But what about starting the APU ( once we have done the important stuff of course) and using it to pressurise the Cabin.
Assuming we are at a weight where we can maintain say FL210 ENG OUT.
I see the MEL is the only source of guidance ( Turn Off ENG Bleed Switches , PUT on APU bLEED Switch , Turn off wing Anti Ice, See you are FL220 or lower etc etc)
However are we really going to be doing this ( consulting the MEL at this time) ?
Is there any other reference apart from the MEL or systems knowledge that will lead us to pressurising the cabin this way ?
My present company is draconian to anyone who thinks outside the box , following a procedure withiut guidance from a Checklist etc.
Just curious chaps , and ladies , your views ?
