If there was no vibration but N1 and N2 went to zero, then it is a basic engine flameout since there was a yaw and roll. The fact that N1 and N2 both went to zero could be an aberration in the fidelity of the simulator or a deliberate ploy by the instructor to test the pilot's diagnostic knowledge. The presence or absence of airframe vibration is the key to the actions to be taken.
The OP never mentioned anything about airframe vibration yet he did mention the simultaneous falling to zero reading of the N1 and N2. Nor did he mention anything about vibration indicator readings. .
In other words, he failed to include all the relevant items that could have assisted responders to this thread to make a meaningful assessment of the state of the failed engine. For example, did the cunning instructor select a staight forward engine failure (flameout) and simultaneously select a failure of the N1 and N2 instrument indications?
if indeed he did, could that scenario actually happen in real life? Answer: Almost certainly not.
On the face of it, and going by what the OP described, it seems the instructor may have introduced three totally unrelated non-normals at the same time. That was unfair and poor instructor technique.
With the cockpit indications provided by the instructor, coupled by the assumed absence of airframe vibration, the pilot under test should have diagnosed the fault as engine failure - not severe damage. This suggests the instructor was correct even though he used a sleight of hand by failing the N1 and N2 gauges simultaneously with the flameout.
Sorry mate but thats a load of rubbish
Have a read of the comments above. No rotation = severe damage. And if we must keep harping on about vibration, the checklist refers to
airframe vibration so the engine vibration isn't hugely relevent.
