FSX/P3D. When taking on an aircraft development project that encompass detailed systems, it's my opinion that if the developer chooses to show product previews, the systems should be included. Yes, the exterior model is extremely important and even the cabin is fine and dandy and all that, but seeing the screens lit up and showing the animation graphics is what is behind a real preview. The guys at Next Level Simulations have posted new previews of the ND in action with comparison shots of that found on board the real A380 and thus far, the efforts are looking mighty impressive. See for yourself. Sooner or later, the AS/DA CRJ will start to show us previews like this... right?
