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:
Ground Speed (GS): The calculator returns the ground speed in miles per hour, and the correction angle (Δ) in degrees. However, these can be automatically converted to compatible units (e.g. kilometers per hour) via the pull-down menu.
The Aircraft Ground Speed is computed using vector arithmetic.
