Wind Triangle Calculator

Solve wind correction angle, true heading, and ground speed for flight planning

Frequently Asked Questions

Should I enter the direction the wind comes from?

Yes. Wind direction is reported as the direction the wind blows from, the aviation convention. A wind from 270 degrees is a westerly blowing toward the east.

Which way do I crab into the wind?

Toward the wind. A positive correction angle means turn right of course, and a negative one means turn left, so the aircraft tracks the desired course.

Why is my ground speed lower than my airspeed?

A headwind component subtracts from your speed over the ground. A tailwind component adds to it, so ground speed can be higher or lower than true airspeed.

Is this for actual navigation?

It is an educational flight-planning aid that works in true degrees. Always cross-check with current charts, magnetic variation, and official procedures before flying.
