The Aircraft Ground Speed calculator computes the ground speed based on the wind speed (WS), wind direction (β), a Flight Heading (α) and an Air Speed (AS).

INSTRUCTIONS: Choose units and enter the following:

• (α) Flight Direction
• (AS) Air Speed.
• (WS) Wind Speed.
• (β) Azimuth of the wind direction

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.
