the speed you type in for the autopilot is in air speed right?
So is there a way you can type in the ground speed for the autopilot? Or is there a rule of thumb to convert air speed in ground speed especially when descending and ascending.
The ground speed will be massively affected by the winds at your altitude, so no, there isn’t really a rule of thumb. You will start to get a feel for it as you fly around the game, and particularly at lower altitudes, but until you’re on the ground it doesn’t really matter as long as you’re flying at a sensible airspeed.
