Can we just get a couple of facts right.
This Aircraft was not operating under ETOPS. ETOPS in my time stood for Extended Twin Operations.
Even if it was an ETOPS sector, (assuming it had been a 767 or 777), the shutdown was before entering the ETOPS segment of the flight so wouldnt have affected the figures.
Time will tell on this one, but having flown the 777 for BA I am very interested in the fuel system on the 747. On the 777 the fuel is burnt initially from the centre tank (down to a minimum level)and then from the remaining two wing tanks. What is the procedure on the 400?
How much fuel was left in this No 2 tank (which could not be used for whatever reason) that prompted a Pan call and if we are to believe one "spotter"(and I see no reason why not, I even started as a "spotter") who heard a Mayday call?
