So reading that article about the faaaaabulous flight depart this month in Pro Pilot, one of the pilots there says he's flying the Lear 35, 604, and GIV. I'm thinking that there is probably a reason why for part 135 they will only let you use two type ratings. We do recurrent every 6 months, and alternate between airframes, so basically you are still only 12 months at the most between recurrent classes on one type. Can you imagine going to recurrent for 3 airplanes? Part 91 would certainly be easier, but still....anyway, was just thinking. Going to have to stop doing that....
