Whats the most stupid thing your student has done or said?
Well try this for starters.
I was supervising ta 50 hour student do his preflight walk around his fathers turbine Enstrom 480. When we reached the static vent just in front of the port side door pillar I asked him what it was and what it did. After looking some what lost for an answer he said, " it's a vent, as you climb the pressure out side the aircraft INCREASES and the vent allows the pressure inside the cockpit to equalise with the pressure outside!!!!!!"
The guy is obviously going to be a star pilot!!!!!!
