What is the extent of the National Airspace System (NAS)?

The National Airspace System (NAS) encompasses the entire airspace of the United States, which extends from the ground level up to 60,000 feet. This broad range includes both controlled and uncontrolled airspace and is critical for ensuring the safe and efficient movement of all types of aircraft. The NAS integrates various elements, including air traffic control, airports, and regulatory structures, to facilitate the safe navigation and operation of air traffic.

The designation of up to 60,000 feet accommodates a variety of aircraft operations, including commercial airliners, general aviation, and unmanned aerial systems. Understanding this range is fundamental for remote pilots, as it informs them about the airspace they may be operating in and the relevant regulations that apply.
