Wind beta formula in VSNG

Post by hjsmuc »

Hello, does by chance anyone know which formula Ilan used for the wind_beta value in the situation files? I can't find out how the decimal value in the file is derived from the wind direction in the sim. Thanks.

I think I found it. Similar to the vehicle beta π/180 is used and the formula should be:
decimal = (degrees - 180) * (π / 180) if beta value is >180
decimal = (degrees - 180) * (π / 180) + 2π if beta value is <180
