Navigation General · Piloting & Bearings
Which type of LOP provides the most accurate position line when obtained by radar in coastal piloting?
- ARadar bearing on a point target
- BRadar bearing on an extended shoreline
- CRadar range on a diffuse coastline
- DRadar range on an isolated point target✓ Correct
Explanation
Radar ranges on isolated, well-defined point targets (such as a small island, lighthouse, or prominent headland) produce the most accurate LOPs. Radar bearings are generally less accurate than ranges due to the wide beam width of most ship radars. Diffuse or extended targets introduce ambiguity.
