A320 using of fuel x feed
 

Hello everyone one

i have question regarding using the fuel x feed when losing fuel pump 1+2 in one side .

in A320
ECAM ask to switch on the fuel x feed on if the failure occurs above FL 150.

Let’s say you climbing passing 10000ft you lost both pumps in one side , can you switch the fuel x feed on and continue flight

and why ecam ask to switch on above fl150

They want us to do GFF. Most likely to avoid imbalance edge cases and crew stuff ups.

Though the number itself - strictly FL150 - is most likely for procedure simplification reasons. Check the Gravity Fuel Feeding procedure. FL150 is the 'lowest denominator'.

Blessed heart, enjoy.
