How often must unlighted fixed aids be inspected?

Unlighted fixed aids are required to be inspected every 5 years to ensure they remain effective and safe for navigation. This inspection interval is based on guidelines established by the U.S. Coast Guard which takes into account the need for regular maintenance and evaluation of the aids to navigation. A 5-year cycle strikes a balance between ensuring that aids remain functional and minimizing the burden of frequent inspections. Regular inspections help to identify issues such as damage or loss of reflectivity, which may hinder the aid's visibility and effectiveness to mariners. It is crucial that these aids are maintained to support safe maritime navigation, making the 5-year inspection cycle a standard for ensuring their reliability.
