Accurately determine the Wind Correction Angle (WCA) needed to stay on course. This essential aviation tool helps pilots compensate for crosswinds, ensuring precise navigation and fuel efficiency. Use our calculator for quick, reliable flight planning, along with ground speed and wind components.
Formula:
The Wind Correction Angle (WCA) is calculated using trigonometric principles to counteract wind drift. The primary formula for WCA is:
WCA = arcsin( (WS / TAS) × sin(WDA - CDA) )
- WCA: Wind Correction Angle (degrees)
- WS: Wind Speed (knots)
- TAS: True Airspeed (knots)
- WDA: Wind Direction Angle (degrees, true north)
- CDA: Course Direction Angle (degrees, true north)
This formula determines the angle a pilot must turn the aircraft's nose into the wind to maintain a desired ground track.
