Question 1 - If both engines fail to respond to thrust levers then is fuel starvation to both engines a possibility?
Question 2 - Do BA 777 procedures insist that each engine is fed from separate fuel tanks for approach and landing, or would it be permitted to feed both engines from one tank?
Question 3 - What warnings and indications would the 777 automatically give if the fuel content in a fuel tank was approaching zero?

1. I guess fuel starvation could be one of the possibilities.
2. according to boeing procedures, it is allowed to feed both engines from 1 tank during landing. crossfeed valves may be opened during landing. I don't know about BA procedures though.
3. when any wing tank reaches 2000 kgs or less a FUEL QTY LOW advisory emerges on EICAS. it has a checklist procedure. it calls for flaps 20 approach, all fuel pumps on and both crossfeeds open.
Now then. What is this accident going to do with the ETOPS status of the 777? Does this count as two IFSD (in flight shutdowns) in one day?
