Byork has the best advice, but I will say that the Q400 flightdeck is busy. Unfortunately I don’t have the NGX yet so I can’t compare, but I use the button version of fs2crew with the Q400 and while it does simplify things a bit, it’s still a huge workload for the captain. By comparison, when I use aerosoft airbus and have the FO do his/her part I feel like I’m not doing much at all. If I’m short on time I don’t bother getting into the Q400, it just takes time to get the thing set up. For what it’s worth, Airline2Sim has fantastic instructional packages for the Majestic Q400 that have helped me a lot.
