Wind Correction Angle Calculator

Your details

All speed inputs use this unit. Switch at any time.
The magnetic or true direction of your desired ground track, 0-360 degrees.
deg
The speed of the aircraft through the air mass (not ground speed).
kt
The direction the wind is blowing FROM, 0-360 degrees true.
deg
Speed of the wind. Must use the same unit as TAS.
kt
Enter a leg distance to compute ETA. Leave at 0 to skip.

Crab 12.0° to the left and fly 78.0° true heading.

  • Fly a true heading of 78.0° to track the 90° course. You crab 12.0° to the left.
  • The wind is nearly pure crosswind with negligible headwind or tailwind effect.
  • Crosswind component is 25.0 kt from the right. Check your aircraft crosswind limit before departure.
  • Your resulting ground speed is 117.4 kt.

Next stepAdd the magnetic variation at your location to convert true heading to magnetic heading before setting your DI or HSI.
