Calculate wind correction angle, corrected heading, and groundspeed using true course, true airspeed, wind direction, and wind speed. This free aviation calculator helps pilots solve the wind triangle for planning and navigation.
Enter the planned course, true airspeed, wind direction, and wind speed to calculate wind correction angle, corrected heading, and groundspeed.
This calculator solves the classic wind triangle used in flight planning and navigation.
Wind correction angle is the correction a pilot applies to heading in order to maintain the desired ground track when wind is pushing the aircraft left or right of course.
Without wind correction, the aircraft drifts. By applying the correct wind correction angle, pilots can stay on the intended course and better estimate actual groundspeed.
Course is the intended path over the ground. Heading is the direction the nose of the aircraft points. Wind can make them different.
Groundspeed is speed over the ground after wind is applied. True airspeed is speed through the air mass.
A pure crosswind creates wind correction angle and drift, but little or no direct headwind or tailwind component.
This calculator is built for true course and true wind direction. Keep your inputs in the same reference system for best results.
