Your answer do not help at all, you even do not know what is a fast turboprop EICAS equiped!
I am not talking of Cessnas or King Air even if I have nothing against them or the pilots who fly them, I am talking for example about a Saab 2000 flown on the line and with reference to instruments at M .62, yes we fly instruments with turboprops also...
A pilot with an ATPL rating can do that I guess, and I have some of my friends who flew the same type doing it now on 737, 747 or Buses with no problems, I guess it is more a protectionism and ego matter, a plane is a plane and after training a pilot should be able to fly any kind of turboprop or jet, be it small or big.
Off course there is the selection process which is primarily set to see if you will fit the company needs and search entering in consideration, but why this reduction factor for prop time?
Any body...
