I am still trying to wrap my head around what is actually happening inside the fuel tanks, is the liquid moving around actually simulated in the A350? I was carrying out a test flight from Hong Kong to Joburg SA. Due to a Navigraph error, I forgot to factor in the extra 15% fuel burn compared to the real aircraft; the result was I had around 4T at the top of descent, way less than I should have. This actually highlighted an unseen feature - What I noticed was that some fuel became unusable, but when the pitch angle changed from nose-up in cruise to nose-down in descent, that fuel became usable again.
I thought I understood tank geometry, but this looks like the fuel is moving inside the tank based on pitch angle
I'll add gravity feed for the remaining fuel
