It sounded like he has some pilot experience. He said "I can't even get my nav screen to turn on. It has all the information on it. You guys have any information on that." He may have not flown a caravan before, but I would be really surprised if he hasn't airplanes before. I think he needed navigational assistance more so than aviating assistance. I'd like to hear a lot more of the tape.
More I think about it, maybe he has done a lot of simulation stuff like on Pilot Edge or VATSIM and has done a lot of talking with ‘controllers’ and flying ‘airplanes’. Wonder what the avionics were in the plane and what auto pilot. The Controller was supposedly a CFI. Did he have Caravan experience? Maybe it really wasn’t all that incredible.
