My worst simulator nightmare is to do a check ride with an examiner who is prone to introducing bizarre and ridiculous scenarios.
I have a cold contempt for those simulator check persons described above. These are the fools that give honest simulator instructors the horrors as we try to repair the damage they inflict on unsuspecting pilots who have the extraordinary misfortune to run into these bastards. Worse still are the management people who appoint these creatures as "check" pilots knowing full well their rottweiller reputation.
As we grow older we remember with affection those simulator instructors who taught with quiet humour and left you with your dignity intact. We remember with contempt those that enjoyed a reputation as a career buster and the unbridled power that came with their appointment. They exist in every airline.
