`GS = f(vec( alpha ^o @ "AS" ) , vec( beta ^o @ "WS" ))`

Enter a value for all fields

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 - (
**β**) Wind Direction - (
**WS**) Wind Speed

**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.

- Correction Angle
- Compute the Ground Speed
- Compute the distances between coordinates
- Compute the time to travel between coordinates
- Force of Drag
- Force of Lift
- Lift Coefficient
- vector (3D)
- Speed Needed for Takeoff
- Physics 105
- Glide Ratio
- Wing Surface Area
- Velocity of Air over the Wing

The Aircraft Ground Speed is computed using vector arithmetic.
