So a 139 (or presumably new 412s?) would work for advanced pilot training and rear crew training. Is the 135 ok for the initial pilot training parts?
I'm not a heli guy so just comparing to my multi background where after a piston single we went to the Jetstream and then front line. It seems like capability wise the heli route requires far more advanced aircraft prior to going to operational types. Relatively I see the 145 as being more capable in its field than the Jetstream or Kingair. Going to something like a 139 would seem to be encroaching on front line capability in many regards.
Is it just the nature of the beast that to train new pilots and crewmen you need such large and advanced types?
