CFRs govern aircraft operating on the waters within how many miles of the coast?

The correct answer indicates that the Code of Federal Regulations (CFRs) govern aircraft operating on the waters within 3 nautical miles of the coast. This is significant because the jurisdiction of U.S. territorial waters extends 3 nautical miles from the coastline, which is an important boundary for regulatory purposes, including air traffic control and aviation safety.

Within this 3 NM zone, the United States has sovereignty and applies its laws, making it essential for aircraft operating in this area to adhere to the applicable regulations outlined in the CFRs. These regulations help ensure the safety and efficiency of both maritime and air traffic operations in coastal waters.

Understanding this boundary is crucial for pilots and air traffic controllers, as it outlines where federal regulations apply and helps prevent potential conflicts between different modes of transportation operating near the coast.
