Other than flying one as SLF every now and then I am utterly unfamiliar with the ATR, so please excuse me if this is a stupid question. I was wondering if you guys could tell me how exactly this prop brake works. Is it some kind of mechanical system, or is it a friction brake or something totally different altogether?
How does the ground crew feel about it? I for one would feel somewhat uncomfortable being around a running engine with an engaged propbrake. Is it regarded as if it were a running prop (read: steer well clear of it) or do groundcrew work in that area nevertheless?
