Or the lump of ice in the carb melts.
Its good for ****s and giggles when you are near your home runway as BPF says. But now I have done it once or twice I really can't see the point of doing it again.
There is no point putting it in FI training.
If the FI has an empty aircraft and wants to do it in the overhead again I don't have an issue with that. I don't actually mind them doing it with a student if they do it sensible. I wouldn't these days though.
My first thought though if I heard that an instructor had done it would be. There is someone that is confident with thier own abilitys.
My next question would be where did they do it.
If it was somewhere stupid they would be defined as a fud.
If is was sensible I would find out if they pattered it. If they didn't they would be an hour building fud.
If they ticked all the boxs it wouldn't be mentioned.
