Depends who the student was and there reasoning behind why they did it.
There isn't a right or wrong answer to be honest. Personally I would pull the cb and carry on thinking heap of crap wish it was a tommy.
A 16 year old who couldn't account for themselves would get an earful more to batter some PIC skills into them.
But say a mature student who had at least thought about what was wrong and made an informed decision along with the effects of the condition would get debriefed and thats about it.
Its quite a good exercise to be honest to stimulate the student to think about what if's. Perfect for a bad wx day sitting in the briefing room.
