Navigation PPLintermediate
Describe a practical way to use terrestrial features to check progress along a planned visual route.
Answer
Select prominent features that lie on or near the route, identify them on the chart before or during flight, and compare their observed positions and sequence with the planned route. Use several features where possible rather than relying on one ambiguous landmark.
Explanation
A sequence of identifiable landmarks provides a visual cross-check of route progress and position. Comparing visible features with the chart reduces reliance on a single uncertain observation. This method complements, rather than replaces, other navigation information. **Key takeaway:** Plan visual checkpoints using distinctive mapped features. **Glossary:** **Checkpoint**: a recognizable position used to assess route progress.
