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.

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.
