I have luckly only had one checkride student who I wouldn't get in car with never mind a plane.
What should we do if we think a pilot is mentally unbalanced.
The guy I was with went mental with aggression as soon as he was told to hold. Handeling skills were fine but it was the personality change which occured as soon as ATC wouldn't let him do what he wanted.
What should we do?
A wee phone call to medical at Gatwick?
