While I can't say I'm the Q400's biggest fan I'd happily take it into LCY. From what I've seen in the sim and online it's a bit like the 200 Dash(!) in that it lands better from a steepish approach with a positive flare, especially compared with the power on floats that clatter in and use loads of runway.
Jam Jar - it's a myth the the 400 needs to be landed with power on - if you can't consistently get off 15 at BHX down the short runway (and with minimal use of the brakes) then I suggest you have a serious look at your flying technique.
Allmc - BHD is no problem at all - we've got performance data for runways half as long!
