A crucial question that has never been answered is the following.
Irrespective of the problems caused by the fuel and its associated systems is the fact that the B 777 may have been outside the enviromental envelope.
This envelope is part of the limitations and certification and needs to be respected a all times.
That'll need a bit of clarification.
I have wondered for some time when - and if - the
definitive cause of BA038s loss of thrust response will be decided, because I don't think it has, yet. None of which, it seems to me, has anything to do with Captain Burkhill, who dealt with the
consequences of the failure.
