OK, but here's one more piece of detail you'll need if you want to work on the flight model -- the indicated airspeed correlation table: Full flaps: 43 kias = 50 kcas 50 kias = 55 kcas 60 kias = 62 kcas 70 kias = 70 kcas 80 kias = 79 kcas 90 kias = 88 kcas 100 kias = 96 kcas 104 kias = 100 kcas No flaps: 50 kias = 58 kcas 60 kias = 65 kcas 70 kias = 73 kcas 80 kias = 81 kcas 90 kias = 90 kcas 100 kias = 99 kcas 110 kias = 108 kcas 120 kias = 116 kcas 130 kias = 126 kcas 140 kias = 134 kcas 150 kias = 144 kcas 160 kias = 153 kcas We need to model this in FlightGear; otherwise, either (a) our flight models will be wrong, or (b) the book numbers won't work with our flight models. For example, the PA-28-161 POH says that the plane stalls at 50 kias at maximum gross weight -- if a user tries it when the ASI is displaying calibrated airspeed (as it does now), the ASI will indicate 58 knots when the plane stalls, and it will look like the flight model is broken.
