Select all correct statements regarding runway designations and magnetic compasses.
Answer
Runway designations are based on the magnetic heading rounded to the nearest ten degrees.
Explanation
The material identifies NM and km, notes that electronic devices can influence the direct-reading compass, and explains runway-number changes through magnetic variation. Physical reconstruction is not required for a designation change. **Key takeaway:** Magnetic references affect both compass readings and runway labels. **Glossary:** **NM**: Nautical mile; **magnetic direction**: Direction referenced to magnetic north.
