Recorded data shows the aircraft had enough fuel and its automatic throttle and engine control systems had worked as expected, the AAIB said.

AAIB make a new safety recommendation re 777. Time to update the checklists:
Safety Recommendation 2008-009
Boeing should notify all Boeing 777 operators of the
necessity to operate the fuel control switch to cut-off
prior to operation of the fire handle, for both the fire drill
and the evacuation drill, and ensure that all versions of its
checklists, including electronic and placarded versions
of the drill, are consistent with this procedure.

From a Delta pilot who now tests weather related equipment:
"Here is the latest on the B-777 crash at LHR. All flights flying from the Far East to LHR on the morning of the crash entered an extreme cold air mass and had to descent to a lower FL to get out of the cold air. Some flights had to go down to FL 250 to get out of the cold air. Every flight across Russia that night and morning had to descend to keep the fuel from freezing but the BA flight in question did not. Investigators are looking into the theory the fuel temp bulb that sends the Fuel Temp Low Caution message to the EICAS may have been sending bad info.
Neither Delta nor the industry have a way to test the fuel temp bulb to see if it is sending the proper info. If the fuel temp bulb is inop that is easy to tell. However, if the bulb is sending incorrect info, that is another story all together"
Curious, what is the temp that jet fuel freezes. Never thought of that before.
On the Airbus the temperature of JET A1 is -43 degrees Celcius minimum temperature and I have got the message on the ECAM couple of times about fuel temperature and not much you can do but I donīt think that would have been the cause to shut both engines just before landing... But who knows... Thanks for that info RalphW
