Absoluely amazing that Boeing/Alteon recruited such non rated pilots as instructors and pulled wool over their customer airlines.
The sim is a good tool to check on adherence to SOPs, procedures, etc. However we all know that the sim can never replicate the handling characteristics of an actual aircraft. However good the visuals are, they are synthetic. A instructor/checker worth his salt surely knows that and will duly factor that in his assessment of the checkee.
This thread makes great reading for all pilots. Much as I sympatise with babablackship's mentor, I think that are many of his ilk out there who indeed need such a wake up call.
