Perhaps you could give me your opinion of the fuel on touchdown after completing one visual circuit
A 744 will use about 1200kg during a visual circuit. This flight actually had 5700kg when it arrived on the gate so probably about 6000kg on landing. It would therefore have had about 4800kg after a circuit. The minimum reserve at this weight would have been about 4300kg.
As was explained on the other thread the crew declared a Mayday because they mistakenly thought, at the last minute, that some of the fuel in #2 tank might have been unusable, which was not actually the case. Diagrams of the fuel system explaining this are on the other thread.
If we are to learn something from this then perhaps we should look at our simulator training. At present an outboard engine is always failed as this is the most difficult to handle and so the crews are well practiced in balancing the fuel after an outboard failure. Perhaps we need to practice inboard failures, with the subsequent fuel balancing, as well.
