I did my private and instrument training (and tailwheel) at LeTourneau a few years ago. Got my IR in 2012 and haven't flown much since, but I'm looking to finish my flight training and finally break into a career of commercial flying. I'll most likely go to a flight school with six pack airplanes, and the thought of redoing my instrument training and doing an IPC in a non-G1000 airplane is daunting to say the least. It will be like starting over from scratch. But I know it needs to be done. In many ways, I feel cheated having done all of my instrument flying in LeTourneau's G1000 Skyhawks. It was way too easy. In comparison, doing it all sans glass/GPS seems incredibly difficult. I feel like I was done a disservice by LETU. Thankfully, I was at least smart enough to not go for the aero science degree, and instead got a B.S. in business administration; the flight training was on the side. I agree with everyone in this thread who has said that instrument training should initially be done on six pack instrumentation. A pilot should first "earn their stripes" the old school way, so to speak, and once they prove they can do it on steam gauges, only then should they be given the privilege of G1000 instrument flying. My old man is a retired airline pilot, and even he didn't steer me on the correct path in this regard.
