The capt. has power on during the landing at different settings and yet tries to lower the nose to -8 deg in order force the plane on the ground. Sounds to me like poor training!?
Quite a few ATR pilots use "power on" during landing and it is not the correct procedure. I have seen many exercise this in Aer Arann. Like any other plane the ATR needs to be in power idle and ATR standard is you "cut" the power at 20 ft and start flaring it.
