I happen to be that PFE that washed out of the last ATI training class. My sim partner, a guy coming over from flying caravans was of course a bit overwhelmed. But given his background that's normal. He was a good guy, working hard with a good attitude. But he was let go. I don't know why. In the past I've seen this company bend over backwards to help someone in his situation. In my case, I'm low time about 400 hours total (not counting my few thousand hours as a PFE). I was told the same thing, after 4 days no further training would be done as it was felt that we couldn't make it. I felt that I did no better or worse than many of the PFE's at ATI who upgraded in the past. After talking with the chief pilot, he did in fact mention to me that there was a philosophy shift in the training department. After being given the bad news from the check airman/instructor , I asked for a critique of my performance. Looking to get some answers to better myself for next time. I couldn't get a straight answer. If I can't even fly straight and level I'm big enough to accept that, but no answers were given. So with the last class here at ATI, 2 out of 6 have made it to IOE. Where is this going with ATI? I don't know. I do know that we are way behind the power curve for our future planned growth, this only hurts us more. For those of you at ATI who read this, I even did the dreaded 3 engine NDB into LAX sucessfully.
