EASA NAV(A)intermediate
Match each aeronautical chart and navigation term with its correct description: Terms: 1. Mercator projection 2. Conformal projection 3. Chart scale 4. Coordinated Universal Time (UTC) Descriptions: A. Preserves local angles and the true shape of small geographic features B. Represents rhumb lines (lines of constant compass direction) as straight lines C. The ratio of a distance measured on the chart to the actual distance on the Earth's surface D. The standardized 24-hour time reference used internationally in flight plans and aviation communications
Answer
1-B, 2-A, 3-C, 4-D
Explanation
Each term describes a separate tool or property in navigation. Conformality concerns angles, while scale relates map measurement to actual distance. Mercator charts make rhumb lines straight; UTC provides a standard time reference. **Key takeaway:** Distinguish projection properties from scale and time standards.\n\n**Glossary:** **Scale**: map-to-ground distance ratio; **conformal**: angle-preserving locally.
