Which group is advised to develop map-type visibility charts to augment photographic visibility markers?

• A. Observing locations.
• B. Deployed locations.
• C. Aircraft Mishap.
• D. Control Tower Visibility Aids.

Answer: (A)

The idea here is to plan and communicate what is visible from specific observation points by turning sight lines and visibility ranges into a map-style chart. Observing locations are the ones that monitor and record what can be seen from fixed points, so they’re the group best suited to create these charts. These maps help them visualize coverage, identify gaps, and line up photographic visibility markers with actual visibility from those points, making the markers easier to verify and use consistently. The other groups don’t align with this task: deployed locations are field units, while aircraft mishap and control tower visibility aids relate to investigations or aviation operations rather than developing and using visibility charts for observer markers.
