Did some test flights and although i saw the value changing once when throttle was applied, in another flight the value stayed at 0 while taxing for departure, got enumerated on air and returned to 0 on touchdown...I'll report it to asobo.
Ok, strange - its different from what I see here. In MSFS2024, I don't even need to apply any throttle, but in MSFS2020 I sometimes need to apply a touch of throttle to see these values, but only occasionally.
Presume you have all rudder assistance options turned off, but might also be worth checking that your turbulence setting is realistic, and maybe also check the values of the simvars ground_crosswind_effect_zero_speed and ground_crosswind_effect_max_speed, which can also affect the wind values on the ground. You can check these values by either adding them to spare/free FSUIPC offsets, or by using the SimvarWatcher utility program, which is available in the MSFS2020/2024 SDK (if you have that installed, but probably not!).
Also, have you tested this in multiple aircraft? Maybe also worth doing before reporting, and if you are just using one aircraft let me know what that is and I will check here (if I have it!).
