Who must be informed whenever rubber-supported cables are in place at the approach end of the landing runway?

• A. U.S. Marine Corps and U.S. Navy aircraft
• B. Air carrier and civil aircraft
• C. All aircraft
• D. Civil and U.S. Army aircraft

Answer: (D)

Hazard awareness and coordinated notification are essential when anything on the runway approach could affect landing safety. Rubber-supported cables at the approach end present a clear risk to aircraft as they near touchdown, so alerting the operators most likely to encounter that setup is necessary. Civil and U.S. Army aircraft are the groups whose operations would be impacted by such a arrangement on that approach, so they must be informed to plan accordingly and avoid surprises during final approach. Navy and Marine Corps aircraft typically operate under different coordination or at different facilities, so informing them here isn’t required by this scenario. Notifying all aircraft would be unnecessary and could create confusion, while narrowing the notice to civil and Army operations ensures the right people receive the warning.
