Thanks,
Interesting point about burner pressures and electrical resistance and resultant wear. A very good point many (including myself) don't consider. But as I said, I'm really MORE concerned about the actual physics of the flameout due to turbulence.
The engine is indeed the CF6-80C (and -80A) on a 767.
As I dig deeper, I see the practice of using ignition during turbulence as kind of "old school".
But just for the sake of discussion (assuming no auto-relight on a generic jet engine) how does the fire "go out" during heavy turbulence? We can even talk about the old "straight pipe" turbojets rather than high bypass fans.
