Anyway, I always assumed that anything of that nature must be on the flight deck.
You know what is said about 'assumed'...
At one airline I worked for, long ago, they provided ops manuals and the QRH directly from Boeing...with the airline logo printed on the cover.
Worked like a charm.
I would ask...who knows more about the specific airplane desired operating procedures, than the original manufacturer?
Airlines...who try to fit a 'one size fits all' scenario?
Hardly...
