Whirlbird . I,ll put a tenner on it that he,s either a nutter or 13 yrs old !!!!
I,m all for encouraging people but " i want to be a 135 pilot when i,m older " seems a tad on the "simple" side .
I would alo say that if he is offended by this then he definitely is heading into the wrong profession .
Of course you can learn on anything but the art of flying within a small power range , throttle control etc can only help make you a better pilot. Who knows , one day you may need to modulate the throttle yourself on your turbine and your previous experience on pistons will be invaluable .
Having said that i may be totally wrong.....
