` = Delta(vec( alpha ^o & "AS" ) , vec( beta ^o & "WS" ))`

Enter a value for all fields

The **Flight Navigation Correction Angle** calculator computes the navigation angle/azimuth correction angle (Δ) using the wind speed (WS), wind direction (β),*Correction angle parameters* Flight Heading (α) and an Air Speed (AS) .

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

- (
**WS**) The wind speed - (
**β**) The wind direction - (
**α**) The flight angle(azimuth) - (
**AS**) The air speed

**Navigation Correction Angle (Δ): ** The calculator returns the angle in degrees. However this can be automatically converted to compatible units via the pull-down menu.

- Compute the Ground Speed
- Compute the distances between coordinates
- Compute the time to travel between coordinates
- Compute the Navigation Correction Angle

The Navigation Correction Angle formula calculate the course correction angle needed to compensate for wind of a certain bearing and at a certain velocity in order to continue at the desired heading. This is done with vector arithmetic.
