Windsheer,
Yep, Chesty is talking about the dash - Q400 mind you rather than the similar looking 100/200 or 300. Despite popular public opinion - "its got propellors, how old is it?" - it is a modern aircraft crammed with computers which do pretty much everything except for moving the control surfaces whilst it is being hand flown. On start up these sometimes have little hissy fits due to voltage spikes when switching generators etc and need resetting, generally by pulling and resetting circuit breakers but in extreme cases by depowering the entire aircraft - which can be a little embarrassing on a dark night with a load of passengers on board!
