Flying Bull.
Your'e going to have to dig deep, very deep, not to blame the pilot on this one. ALL evidence allegedly points to pilot error on more than one count (fuel management / double engine failure handling).
As mentioned (for the Nth time) the fuel system couldn't be simpler.
From memory, there was a tendency for some pilots to switch the boosters off to prevent the captions from illuminating after a while sitting nose up. Departing the hover removed this issue but you had to remember to switch the boosters on again during cruise!
As for you landing on with captions, stopwatch running and a 'plan' to land with engine(s) out - that scares me and I can only hope you weren't somebody I mixed with in the profession wehn I flew Airbus 135's.
There is NO excuse to keep the cab operational when you enter low fuel territory. It's bye bye ground forces and hello base - ALWAYS.
You have 2 or 3 innocent crewmembers on board who rely on you NOT to put them in danger.
I will therefore assume I have misread your post.
