Most turboprops whilst on the ground with FI selected are off and running
I do agree with that statement. Every turboprop I've flown, except the Nomad, will happily move off the blocks at Flight Idle. The B200 is a good example even at max weight. If you are turning off a bay then sure power will be required but if its straight ahead then 9/10 times as soon as the brakes off, off it goes. And your soon into Beta to slow it down.
So do you have to pull beta to get the aircraft on the ground ?
What do you think? There is a big difference between a B200 (or whatever) overcoming ground friction than the same aircraft trying to stay in the sky with a s**t load of drag from flaps, gear, wing etc.
