A good operator in a Turboprop will be a good operator on a jet.
Fully agree!
I came from a commuter size turbo prop and didn't have a problem, neither did any of the other people in my class with similar back grounds, nor the people in the class before and after me.
It's one of those typical old fashioned, out of touch, ideas that people who have flown props are no good. Perhaps it was like that in the 1950's when NSF got into aviation, but believe it or not, things have progressed considerably over the course of 5 decades...
As seasexsun pointed out earlier, automation levels (EFIS, Cat III etc) are roughly the same and so are approach speeds. The only thing missing in general is autothrottle/thrust. Perhaps descent planning is a bit
different because jets tend to be a bit more slippery than props, but that should be nothing that any average pilot can't fix. Just different numbers, like pitch and power...
There has to be a first time for everything in life, all it comes down to is; good selection, good preparation, good training and the proper attitude.
