indeed he was at no stage short of fuel and therefore never, in his mind, taking any risks. And I believe that is why the double flame out was such a shock and a successful outcome beyond his ability.
i think Captain Trail’s probable belief that both transfer pumps were on when in fact both were off persuaded him to ignore subsequent warnings.
i did read every word of the FAI report. I can’t help agreeing with its findings.
But I think that the fuel system of the 135 is an abomination waiting to trap the unwary in a totally false illusion that each engine has its own fuel supply to meet regulation.
ive never flown the type, but it seems to me that there is never a time when both transfer pumps would intentionally be off together.
so why not a single three position switch. Centre - Both on. Forward - Forward on Rear off. Rear - Rear on Forward off.
and if you ever need both off a separate guarded switch to turn both off.
