Hello,
I have the distinct impression that the mathematical formula provided in the UH-1H profile of DCS.ExportScript, namely math.atan2(lon2 - lon1, lat2 - lat1), is not correct.
The correct mathematical formula seems to me to be: θ = atan2( sin Δλ ⋅ cos φ2 , cos φ1 ⋅ sin φ2 − sin φ1 ⋅ cos φ2 ⋅ cos Δλ )
where φ1,λ1 is the start point, φ2,λ2 the end point (Δλ is the difference in longitude)
When I do tests with this new formula, I have almost no more discrepancy with the bearing determined with the rule of the F10 card.
The distance calculation formula, on the other hand, seems correct.
