EASA NAV(A)basic
Match each aeronautical navigation term with its corresponding definition: Terms: 1. True Course (TC) 2. Magnetic Course (MC) 3. Magnetic Variation 4. Compass Deviation Definitions: A. Angular difference between magnetic north and compass north caused by aircraft-specific magnetic interference B. Course measured with reference to true geographic north C. Angular difference between true north and magnetic north D. Course measured with reference to magnetic north
Answer
1-B, 2-D, 3-C, 4-A
Explanation
These definitions identify the reference used by each navigation direction and compass correction. **Key takeaway:** True-to-magnetic uses variation; magnetic-to-compass uses deviation. **Glossary:** TC: true course; MC: magnetic course.
