Its a very nice application, but there are a few problems:
First, the altitude shows AGL, whereas it should show MSL. (If you want to show an AGL altitude, add a Radar Altimeter output.)
Second, the speed indications arent very realistic. It appears that the system shows either TAS or GS, but it should show IAS.
Finally, a mission briefing would be nice, telling the player whats actually expected (before you go wheels up). Otherwise, youre just guessing on what you mean by "intercept" or other loosely defined terms.
Just my two cents. :-)
UPDATE: Just two more gotchas.
1. A rudder would be fantastic!!!
2. Why can I only use about half of the platforms landing pad? It seems like whenever the aircraft goes more than halfway across it, it crashes. Alas, when lifting off, sometimes the noeswheel “sticks” dragging me into the invisible wall.
