Which group must be informed about rubber-supported cables at the approach end?

• 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)

The key idea is that runway-end hazards need targeted briefing for the operators who actually use that airfield in a way that could expose them to the danger. Rubber-supported cables at the approach end pose a specific risk to aircraft on final approach, so pilots need advance notice to plan their approach and avoid or anticipate the hazard.

Civil and U.S. Army aircraft are the groups that must be informed because this setup is typically encountered on joint-use or shared fields where civil aviation and Army operations overlap. Informing both ensures pilots from commercial or general aviation and Army units can proceed safely with appropriate awareness and procedures. The other groups aren’t the ones at risk in this particular scenario on that approach end, or the rule isn’t aimed at all aircraft universally, but at the civil and Army operations using that field.
