Having visited some other threads dealing with the Q400, I came to notice that the latter does not seem to be very convincing reliabilty wise. Many drivers complained about it as a fragile machine eben though it offers good performance....
To make a comparison with the ATR 72 which of ocurse does not cruise as fast but offers the possibility of being operated as a full cargo cargo aircraft with the Quick Change kit, does that give it an advantage on 300 to 400NM over the Q400 and RJ's (CRJ 75)??
