I am a real crj pilot and purchased this to help with my initial training, however the systems fall way short of simulating the real thing. For example the 14th stage bleed valves always remain open except for first flight of day tests in which they are cycled to confirm the valves work. Without these valves open there would be no reverse thrust or anti-Ice as these depend on 14th stage bleed air. The fuel system is not accurate, as it is driven by motive flow with the boost pumps automatically turning off once the engines are started and automatically turn back on only if the motive flow pressure falls below minimum. In this sim the fuel pumps are always on. There are a bunch of system issues like this, the only thing I like about this is that the visual model is very well done
