Problem calculating crosswind with offset 2DC8 in FSUIPC 7
Good day.
I've been using offset 2DC8 to calculate crosswind. It works perfectly on all fsuipc versions except on version 7.
According to documentation, the output should be (+ve Right Crosswind, -ve Left) but in version 7 the values are inverted (-ve Right Crosswind, +ve Left). Though it can be fixed easily by multiplying with -1, i thought i should mention it.
Furthermore, it always returns 0 while on ground.
Is this in MSFS2020 or MSFS2024, or both?
Offset 2DC8 contains the simvar AIRCRAFT WIND X. The documentation for this simvar doesn't actually state the direction for +ve/-be values. I can do one of three things about this:
- raise with Asobo to see if this can be changed
- update the documentation to reflect the correct wind direction
- reverse the value received before populating the offset
I think it probably best if I report to Asobo and update the documentation. I would need to revert the documentation if Asobo decided to fix this though.
The documentation (in MSFS2024 - see https://docs.flightsimulator.com/msfs2024/html/6_Programming_APIs/SimVars/Aircraft_SimVars/Aircraft_Misc_Variables.htm#AIRCRAFT%20WIND%20X) also states:
It should be noted that if the user has rudder assitance options enabled, then the simulation will force this to 0 in takeoff situations.
Not sure if thats also true in MFS2020 (but I would suspect so) the documentation in MSFS2020 is pretty sparse and only says 'Wind component in aircraft lateral (X) axis.'.

It happens in both MSFS2020 and MSFS2024. Since i've doubt there's gonna be a simupdate for 2020, i believe the best and more direct approach would be to reverse the value for FSUIPC 7, but that's up to you!
I will first post in the Asobo developer forums about this issue, and decide how to handle this based upon any response. I will keep you updated.
Is the 0 wind issue on ground also in both? And do you have the rudder assistance options enabled? Do you see wind if you disable them?
I will also check this here...

I'll check and let you know. Thank you for your fast response!
Tested in both 2020 and 2024 with auto rudder on and off, makes no difference, crosswind is always 0.
Ok, I will take a look and report to Asobo.
