Simple ND

This Navigation Display (ND) shows a crude compass rose and calculates the local wind direction (blue marker) with wind speed (blue number) and ground speed (green number).

Additionally, an altitude input is shown on a kind of radio altimeter scale, indicating your clearance to ground.

The relativ wind (calculated from vehicle and wind speed) is output and can be used for other appliances. (e.g. Richman's Weather Logger).
