While trying to play on winds to test my flows for a future release of LFRD on the gateway, I noticed that a 20kts wind made it impossible to keep a direction during taxi on grass. (C172)

Today, with XP11.0pb10, and the same laminar C172, a friend of mine (leisure pilot too) tested the simulator and had the same impression as me, that a 10kts wind was generating too much constraints on the aircraft when taxying on the ground.

When cruising, we could also notice that we were drifting by 15°, where we would have expected 5° in full cross wind : cruising speed of 120 kts, wind set to 10 kts up to 3000ft.

Thank you very much for all your fantastic work.

It appears as though this is still an issue.

I have spent a good 2 hours troubleshooting my hardware (5 Nov 17) to confirm it was all calibrated correctly. Then moved on and spent 1 hour testing various settings in XP11 till i noticed that the aircraft would straighten out once it got to a certain heading. Then I tested taking off and landing into a head wind and found that I did not have to max out my left rudder just to stay on the runway.

The version I am using is 11.05

Maximum wind correction angle is 60 / TAS * wind speed, 60/120 * 10 = 5 degrees

So indeed should have been 5 degrees, not 15 degrees.

I now checked on pb11 with wind fully cross at 20 kts and flying 120 kts on an ILS localizer steady at 2000 ft AGL with a Piper Archer 28: wind correction angle is indeed 10 degrees as it should be.

So if there was a problem it looks to be solved.

Indeed, although there is no such fix mentionned, It now seems to be all solved in beta11. I do not know who fixed it and how, but thank you so much for your prompt correction!!
