What is the angle between true course and true heading called?

Variation relates true north to magnetic north; deviation relates magnetic north to compass north. **Key takeaway:** WCA corrects for wind drift.\n\n**Glossary:** **Course**: intended ground track; **heading**: direction the aircraft nose points.
