Has anyone ever had a line training flight where the TRE/I encourages or suggests flying it from 10000'. No, because although they say its training and that's the time to do it...it's checking...and he will will "2" you if you get it wrong...."But I thought this was training" won't get you anywhere with the Interview panel....never mind that the TRI could have only been a Capt for six months anyway.
Dunno, first flight on the line with on a jet during linetraining and the trainer asked me to switch it all off at FL170 and fly it manually raw data for the rest. From there it happened at least once a day, qite often for the whole sector, until i was out of line training. And since i thought it a nice idea i do the same still today. However, that was training in europe in an airline that had a serious training department.
