Ground Speed

KurtHeckman.Ground Speed

The Aircraft Ground Speed calculator computes the ground speed based on the wind speed (WS), Flight parametersa 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.
