When I did my PPL I had a great instructor, it's been years but we always kept in touch. I gave him a call, to my surprise and for family reason he is bask flying the Q400 for Air Canada (he was on a A320-200), so I ask him a few questions on landing the Q400 and explained how our simulator behave VS the real thing. Since he is a bit far away we decided to watch together a few Youtube video of some cockpit view landing.
So I did a few landing and filmed everything and showed him.
First he was amazed by the realism of the simulator, he didn't know that public Simulator where so realistic.
First the rudder (yaw) trimming, that a true as hell but mostly on power variation, not much where you set for landing. He saw that on landing I was playing constantly with the yaw trim and he told me, well stop that and fly the plane meaning use the rudder if needed.
Flap at landing, IPACS is right, not fully extracted unless you are doing a STOL landing and also it's depending n the wind.
Flaring, about none with a Q400, I said why? He replied it want to fly at all cost, we even have to push it down and sometime keep some elevator down wile braking (see the video bellow) , I laugh when he said simply, it's a high wing thing
Power at landing (if the slope is good), about 15% and you may go up to 30-35% (see last video) before-at flaring... or NOT.
He said to conclude, it's a more sensitive plane in general....
ps. I will put mine online later, maybe some other could do so, that could be fun.
