What must be followed by U.S. LE units while operating in coastal State airspace?

The correct response emphasizes the importance of adhering to Coastal State aviation safety procedures while U.S. Law Enforcement (LE) units operate in the airspace of coastal States. When operating within the jurisdiction of a Coastal State, LE units must recognize the sovereignty of that State over its airspace, which includes all regulatory and safety guidelines established by the State.

These procedures are designed to ensure the safe and orderly conduct of air operations and help integrate military or law enforcement activities with civilian aircraft operations, protecting both the mission of the LE units and the safety of other airspace users. By following these procedures, LE units can maintain effective coordination and cooperation with local aviation authorities, thus minimizing the risk of accidents and incidents in crowded airspace.

This choice specifically highlights the legal framework and local requirements that govern aerial operations, focusing on the responsibilities that come with operating in another jurisdiction's airspace, rather than broader protocols or regulations that may not directly apply in this context.
