The **Aircraft Ground Speed** calculator computes the ground speed based on the wind speed (WS), *Flight parameters*a wind direction (`beta`), a Flight Heading (`alpha`) and an Air Speed (AS).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**WS**) The wind speed. - (
**β**) The azimuth of the wind direction - (
**α**) The flight heading - (
**AS**) The air speed.

**Ground Speed (GS):** The calculator returns the ground speed in miles per hour. However, this can be automatically converted to other velocity units (e.g. kilometers per hour) via the pull-down menu.
