EASA NAV(A)basic
Match each aviation navigation term to its correct definition: 1. Nautical Mile (NM) 2. Compass Deviation 3. Runway Number Definitions: A. Runway centerline heading rounded to the nearest 10 degrees magnetic B. Standard unit of distance equal to one minute of arc along a meridian (1,852 meters) C. Angular difference between magnetic north and the direction indicated by the aircraft compass
Answer
1-B, 2-C, 3-A
Explanation
These pairings distinguish the navigation unit from magnetic-reference concepts. Runway designation is based on rounded magnetic direction; deviation is a compass error. **Key takeaway:** Keep distance units and north-reference corrections distinct. **Glossary:** **NM**: Nautical mile; **deviation**: Compass-related magnetic error.
