I understand your point regarding the term Flame Out. My understanding of this term is its a situation where a Turbine Engine fails to continue operation due to inability to maintain flame propagation through any of a number of extinguishing events. Off the top of my head these would include: Compressor Stalls, ...
I once worked a pilot writeup of "Flameout with increasing EGT..." which of course is an oxymoron. It was a compressor stall, period (caused by sand/dust erosion) with NO flameout, but RPM rollback.
The term "flameout" is, I'm afraid, still misused by some of the aviation community, and actual flameout (oxidation ceases in the burner) is quite rare, save for fuel starvation.
Correct me if I'm wrong, but I don't believe Sully's CFM56's ever flamed out.
