EASA NAV(A)advanced
Explain why prominent ground features are preferred over minor features for visual navigation.
Answer
Prominent and continuous features such as rivers, railways, and highways are generally easier to identify, follow, and match to a chart. Small tracks, creeks, or boundaries may be difficult to distinguish or may be obscured, so they are less dependable as primary references.
Explanation
Visual navigation depends on correctly recognizing the feature seen outside and matching it to the chart. Large, continuous features reduce the chance of confusing one landmark with another and make it easier to monitor progress along a route. **Key takeaway:** Choose conspicuous, charted, and continuous features, then cross-check them. **Glossary:** Terrestrial navigation: navigation using Earth's visible surface features; cross-check: verification using additional references.
