Wind Discrepancy and Conversion bug

Wind conversion error and difference across measurement types.
The wind set with the weather tab does not align with the indicated wind or headwind in the debug window, or the airspeed indicator.

Aircraft on ground facing 360deg engine off, pitot cover removed. Clear sky’s, set 50Kts no gusts at 360deg. I’ve used this as an example.

When the debug weather view is open as seen in pics and cross checking this with the ASI and the debug there is a difference between the speed indicated/headwind and the set wind, and it varies between Imperial/Hybrid/Metric measurements as shown.

Red arrows I’ve place show wind speed that should all match up but you can see the differences.

Purple arrows show there’s a difference between the fps calculation on the indicated and the headwind which at this position and heading should be identical, and this is repeatable .

Yellow arrows show typos in the debug window, its missing a numerical figure for the mph on the indicated wind speed line, and the ‘f’ is missing from the ‘fps’ part of the indicated as well.

There is also another strange issue with the wind in that if you close the drop down weather window and reopen it increases the wind speed up on opening. This is also repeatable and occurs every time.

This probably is not a bug. The simulator must reconcile among different data sources and their ways of specifying the wind information, in addition to representing the wind profile that is determined with the surface roughness, boundary layer stability, terrain shape, etc. Pretty much the only place one could potentially require the FS wind to match either METAR, or UI prescribed, would be at the location of the aerodrome weather station and 10 meters above ground.

While I understand what your saying, this does not explain the typos in the debug software and the difference in the conversions across different measurements as I clearly show in the pics. Its easy enough to open the sim and with debug weather open set a wind and try the 3 different types of measurements in the sim. You get basically half the wind you ask for, if on imperial measurements but a knot or two difference on the other ones. There’s some errors in the code.
