Companies that I have flown with will spend 50-100 hours with you before you do fly the line
Did you do an endorsement on the Space Shuttle?
A
turbine is not like a piston twin, i.e a couple of laps around a circuit with a touch of airwork and a couple of hour chat prior. Most are up to two weeks of intensive ground school study, rigid examinations and long periods with a checkie until you are signed off to fly the line.
From my very limited experience in this area ... I don't think so. IRON MAIDEN don't be put off by these comments. If you're talking about a Dash 8 or an ATR where there's a simulator available for a type rating then sure you're going to have the luxury to spend a bit more time. In the smaller turbo props (B1900, Metro, J32 etc) I'd suggest on the line is where all your learning is going to happen.
