Orestes...

I asked in the BA thread is it was possible that the compressors were stalled due to high AOA and mentioned that the TGT/JPT would be excessive in that case with failure to produce thrust but lots of noise! I was concerned about several ground witnesses mentioning unusally loud noises from the engines.

I don't think I have ever had compressors stall in an airliner (except possibly those loud bangs on the ground roll with reverse thrust), but I certainly did in a jet fighter with a Rolls Royce Avon engine.

I felt sure that the recorders would show excessive TGT/JPTs in this case but nobody but you seems to have mentioned compressors at high AOA.

Anyway, my post was immediately removed so nobody saw it and replied
