Be Careful .....
In my original post, I did describe the "soft reboot" fix (which works), but don't forget that we have three possible reasons for strange B777 fuel indications, i.e.
(1) A VNAV problem being addressed by Boeing, the "soft reboot",
(2) Suspect FQI for the centre tank in some instances,
(3) The "Phantom" Wing Fuel assymetry problem, still being addressed by Boeing (which yours truly experienced last night).
Geragau did point out that whilst the "soft reboot" does much to realign the computed fuel with the Totaliser, they tended to drift apart again thereafter (much like INS after a DME update). What he says is TRUE,
BUT, although the in-flight discrepancies might begin again, the more important to me is the PREDICTED Fuel at arrival, and, it is my observation that even though in-flight differences may slowly recommence, the Predicted Arrival Fuel is
MUCH more in line with reality.
Three FQI oddities for the aircraft, I say again
Be Careful .....
