Ditching and swimming procedures are in the QRH - Fuel leaks are not
May be not in your flying time, I do not know. Nowdays YES.
For the Canadian A330 - It was not covered by their QRH (or SOPs).
Sorry, but wrong again. Please, review Canadian accident history.
The Transat crew made wrong consideration assuming no possible leak and followed the "wrong" QRH path. If they whould have checked carefully the FOB+burn against the loaded one the "problem" would not have happened.
No engeneering manuals needed, simply follow QRH.
it is all "by thebook" now and very little thought outside the box.
This because statistics say that in modern aircraft there is a big percentage of accident due to application of "personally theory" derived from "too deep" knowledge of the acft sys.
