What should the OU do when a non-reception range ring intersects with a line of bearing?

• A. Ignore the intersection and wait for more data.
• B. Plan to search the entire LOB since it's considered to be a reasonable search area.
• C. Reassess using a linear search along the LOB.
• D. Search only the area within the non-reception ring.

Answer: (B)

When you encounter a non-reception range ring intersecting a line of bearing, you don’t have a precise location from the bearing alone because signals aren’t being received within that ring. The actual subject could lie anywhere along the bearing outside or at the ring’s boundary. Treat the line of bearing as a reasonable search corridor and plan to search the entire LOB. This approach uses the available directional information while accounting for the uncertainty caused by the non-reception zone, giving you the best chance to detect the subject with the data you have. Ignoring the intersection or narrowing the search to just inside the ring would either miss potential locations or rely on insufficient information. A linear search along the bearing would likewise risk missing areas outside the narrowed focus.
