I've found a serious, and surprisingly not-previously-detected YASim bug. The calibrated airspeed does not allow for wind. Here's an easy way to test it:
1. Take a YASim plane (such as the J3 Cub), fly to altitude, then level out. Note exactly where the horizon is on the screen, and record the indicated airspeed from the panel (mph) or HUD (kt). 2. Pause the sim, go to the wind menu, and set a 20kt headwind. Unpause, and adjust so that the horizon is at the same position as before (the nose will try to rise up initially). You should note that the indicated airspeed in the HUD (if open) and on the panel is 20kt lower than before. 3. Pause the sim again, go to the wind menu, and set a 20kt tailwind. Unpause and bring the horizon back to the same spot again (the nose will initially plunge). You should note that the indicated airspeed is now 20kt higher than before. Before I plunge in to try to fix this, does Andy (or anyone else) have any suggestions? It looks like there is code that is *supposed* to subtract the wind from the airspeed, but it obviously isn't working.
