tiger1962 Posted March 3, 2021 Share Posted March 3, 2021 I've just posted this on the official forums, I'm re-posting it here for those who don't visit the official forums. If your plane veers off the runway in the slightest crosswind and won’t turn back even with full rudder, this fix may work for you. It’s a formula for reducing the crosswind effect and increasing the rudder authority on any aircraft. I’ve tested the formula on the DA40, C172 and DR400 so far and can take off, fly a circuit, land and taxi them all in a 20 knot crosswind. This fix requires a few edits of the flight_model.cfg file with Windows 10 Notepad and Calculator, that’s all: Open your chosen aircraft’s flight_model.cfg file with Notepad and scroll down to the [AERODYNAMICS] section. Look for the side_force group of entries, there will be four in total: side_force_slip_angle = -2.12726 side_force_roll_rate = 0.25450 side_force_yaw_rate = 3.09566 side_force_delta_rudder = -1.79189 Copy the value for the first entry, e.g. -2.12726, and paste it into Calculator. Now divide by 4. Copy the result and paste it back into your flight_model.cfg like so: side_force_slip_angle = -0.531815 ; -2.12726 The ; between the two values is there to retain the original value while making it inactive. Repeat this process for the other three values. Now look for the yaw_moment group of entries, there will be eight in total but we’re only editing two of them: yaw_moment_yaw_damping = -16.27597 yaw_moment_delta_rudder = 0.64763 Copy and paste the yaw_damping value into Calculator and divide by 2: yaw_moment_yaw_damping = -8.137985 ; -16.27597 Copy and paste the delta_rudder value into Calculator and multiply by 2: yaw_moment_delta_rudder = 1.29526 ; 0.64763 Save the flight_model.cfg file and enjoy the improved ground handling! This formula can be applied to any aircraft with a flight_model.cfg file. Tim Wright "The older I get, the better I was..."

Leadraft Posted March 4, 2021 Share Posted March 4, 2021 (edited) This is great. Been struggling with this for so long. I do like the challenge of cross wind landings though. Does it remove or lessen effects when on approach or just when on ground?

tiger1962 Posted March 4, 2021 Author Share Posted March 4, 2021 It doesn't appear to lessen the effects on approach, or in the air in general, it's just when on the ground while taxiing, taking off and during landing roll-out.
