I glanced at the stick pusher article...if a plane needs a pusher, then it either should have a pusher or not be certified.
so
I do think the pusher should have a substantial warning, like a longer period of stick shaker activation. I also think pilots should have knowledge of such a vital system.
I've flown two airplanes wih pushers *not the Q400 though...both had very large warning lights that the pusher was activated...it also had easy to disconnect pusher methods.
so....what can I say....
