However, bear in mind that flying especially flying in command has a lot to do with confidence. A pilot's confidence is often badly damaged, if not destroyed by failing grades especially when done maliciously. I have seen friends whose confidence plummeted drastically on account of arsey checkers like you; hence my advice is that checkers bear that in mind before they embark on their jehovah moments.
So true, AA. Got a mate who had just a bad day, not a disatrous sim check at all ( I spoke to the checker as well as the f/o ) but the anal checker deemed it fit to fail the guy because " he expected more, not just acceptable standards. " The poor bloke ( who already had some other stuff bothering him leading to the seemingly bad day ) was shattered and he was never the same for a long long time. It was only when he moved to another airline that he fully recovered his full confidence, becoming a superb trainer and checker.
