Jet fuel (as I'm sure we all know) deaerates in the climb and early cruise which is one of the reasons fuel pumps are so important to pressurise the fuel and prevent pump cavitation with consequent engine power loss/flameout.
I have looked in the 'sticky' for any reference to this but none seems to have been discussed before.
My questions are then: If I carry round trip fuel and 'de-aerate' all of it on the outbound sector, will I still be faced with a cavitation problem if I loose the fuel pumps on the second sector?
Does the fuel re-aerate to any extent, and if so over what time period?
Does de-aerated fuel mix with new fuel or will they separate out if left long enough, ie fuel of differing densities?
Merry Christmas to all Ppruners!
