Re simulator fidelity checks where scheduled checks may include engine failures during and immediately after take off. Normally the test crew includes technicians and qualified on type flight crew.
I have often wondered how an engine failure during a fidelity check can be assessed as like the real thing when the assessing pilot may never have experienced a real engine failure on take off in the type of aircraft he is assessing. How valid therefore is this assessment in terms of fidelity? Or is it a case of tongue in cheek "seems OK to me" assessment?
