What is the angle between true course and true heading called?
Answer
Wind correction angle
Explanation
The difference between **true course (TC)** and **true heading (TH)** is the **wind correction angle (WCA)**. Wind may push the aircraft away from its intended ground track, so the aircraft must point into the wind. Variation relates true and magnetic north; deviation relates magnetic and compass north.\n\n**Key takeaway:** WCA corrects heading for wind so the aircraft can maintain its course.\n\n**Glossary:** **Course**: intended ground-track direction; **heading**: direction the aircraft points.
