Whirlybird. I'm with you on your last comment. Sound like that one needs to go for a base check in people management.
As an FI I have found the choice of words can make or break the lesson. Several times I have found myself saying calmly "OK, I don't think that's quite right. Return to straight and level, and I'll demo that again......Follow me through" When inside I've been yelling "What the
are you doing?!"
I'm very good friends with an examiner and he believes in either a pass, pass with a long de-brief into mistakes, a partial, or fail. Having sat in on de-briefs I've never heard him be rude or degrading even if the performance has been beyond terrible.
That sort of de-brief is not good for the student, and if they have spent that sort of money on training (£2.50 per minute) just how demoralising can that be. Plus if they think they are a low quality pass, if they get into a situation that challenges them they'll panic because they'll think they aren't good or confident enough to deal with it.
If he didn't deserve to pass, then fail him and say "go and concentrate on x,y,z then try again"
Having partialled my IR first time out, my debrief as soon as the props stopped turning was "Bu**er! If you hadn't bust that level I'd have passed you. I'm free tomorrow, re-book with Gatwick, go drown your sorrows and I'll see you at 2pm"
Ah well......... there's always one!
