Alltheway said:On the CRJ-200 fuel system is it possible to x cross feed fuel from one side to the other (TO both engines) in a unlikely event of lets see…..you right side engine driven fuel pump fails and also your right side electric boost pump. The fuel layout shows there is a connection between the two just after the left and right boost pumps. thx

did you skip ground school? or is it just the 300 hrs. total time you have?
The problem is, to ask that question an open forum just doesn't make since. you must be joking or really stupid.
Exactly. From "Airplane": "What an A*S hole".DoinTime said:oh my GOD....Cøck Sucker, you must be from Skywest or CHQ.
Absolutely, positively, 100% correct.One boost pump can supply fuel to both engines. On the other hand, one main ejector is only able to feed that side's engine due to a one way check valve that is not shown on the synoptic. My airline (PSA) does a daily check on this check valve on the first flight of the day by turning off both boost pumps once both engines are started. This is done to ensure that you can stop fuel to that engine in the case of fire.
Also 100% correct.If the high pressure engine driven fuel pump fails the engine will not run. Some of this fuel pressure is used for motive flow to operate the main ejector and scavenge ejector.
I’m good with most of this, but you shut off the boost pumps with “both” engines running? What do you look for?piratebooty said:One booshand, one main ejector is only able to feed that side's engine due to a one way check valve that is not shown on the synoptic.
