On a 1:500,000 aeronautical chart, a pilot measures a straight-line distance of 20.4 cm between two waypoints. What is the approximate flight distance in nautical miles (NM)?
Answer
55 NM
Explanation
The chart-based answer is approximately **55 NM**. Distance is measured between the relevant overhead positions; variation affects direction conversion, not the geometric distance. **Key takeaway:** Separate route distance from magnetic-course calculation. **Glossary:** Direct distance: straight-line chart distance between two positions.
