With respect, it's in here. Happy reading.
Further:
Be careful of "Fuel Heating". It is warmer temps that created the hazard, not "very cold" Fuel. (Though it was a precursor).
Location of FOHE? perhaps away from the Fan Shroud a bit.
Bypass, a no brainer. Though GE uses the concept to further cool the oil, in this case, a "recirculation" not strictly a "bypass".
The Bottom Line? The Fuel system as a whole on this combination wants to be a bit more complex, to include additional mitigating procedures and mechanicals. It always looked a little simplistic, turns out it is.
vapilot -It is always hazardous to rely on the unknown, or statistics. If what you mean is "one in one hundred thousand" of an additional occurence, think about how many months it takes the Fleet to hit 50,000 trips. At that point the chance? ONE in TWO. Let's see, 228 a/c, one trip a day, 1,000 every 4 days, twenty thousand every 80 days (Five to One), etc. See?
bernd - re:GE. The HP in front of the FOHE not only "Heats" a little, it makes any free floating ice/slurry into margaritas, "blending" the mix for the FOHE and subsequently for the nozzles. It is this architecture more than any other reason, in my opinion, that makes GE mounted 777's "immune" from "the Plug". GE-"Blended"..... TRENT-"on the rocks".
