Fuel System Design Question.
Re: dxzh post #384
IMHO I believe that it would be extremely unlikely that both engines could have rolled back within 8 secs of each other resulting from an independent (ice or whatever) blockage in each wing tank pick up.
However I believe that you may not be far off target.
Before posting an alternative I would appreciate an answer to the following question.
How does fuel get from the CWT to the engines?
a. Via the wing tanks (i.e.pumped from CWT into the wing tanks then out again using the wing tank pumps) OR
b. direct from the CWT to a rail / manifold etc common with the output from the wing tanks, with the higher boost pressure from the CWT pump giving it priority to supply the engines?
Anybody got a pic?
How many boost pumps (not water scavenge) are there in the CWT. 1 or 2 (1 LH and 1 RH)?
JFI is this a 777 specific or standard approach to engine fuel supply management?
