How to choose runways?

[bolox]

Thanks. Where can I manage the wind direction in FMB?

View>mission parameters >flow

Then alter the figures in boxes to suit. (and you can add different winds at different heights by adding more flows if you wish,)

Wind angle is not intuitive
0 degrees comes from west and the direction is counterclockwise, so 90 deg would have wind coming from South (planes takeoff towards south)
