Visual Aids to Navigation: Dispelling Aid Availability Myths

Aid availability for the U.S. visual aids to navigation system is calculated monthly by the U.S. Coast Guard Marine Transportation Systems Management Directorate's Visual Aids to Navigation Division. These calculations can be presented by criticality category and broken down to various responsibility and servicing levels, including district, sector, servicing unit, waterway, and individual aid to navigation. Frequent updates and convenient data presentation lead many waterways managers to assume that aid availability provides a comprehensive assessment of the health and effectiveness of aids to navigation (ATON) in their waterways as well as the efficiency of their ATON service delivery units. This mistaken assumption has perpetuated several aid availability myths, which are listed and discussed in this article, as are the ongoing ATON resources that waterway managers have available to them.
