Not sure if I am correct or not, however I believe when Impulse pilots went from the 1900 command onto the 717 they needed to have 500 hours in the right hand seat before going for their commands.
Not sure if this was some type of insurance issue or not, I am sure when Qantaslink get their jet equipment a similar situation will exist, and they are coming.
The Impulse guys certainly seem to have adapted without to much trouble, when you consider over the last few years they have gone from 1900, 717, A320, A330 and possibly 787's all from being regional pilots.
Considering the 400's are a bit quicker than the 1900's I would assume the transition would be a little easier than what the Impulse guys had in front of them.
