What is the altitude range covered by the National Airspace System (NAS)?

The National Airspace System (NAS) encompasses a comprehensive range of altitudes, extending from the surface up to 60,000 feet. This altitude range is significant because it encompasses all operations of both manned and unmanned aircraft in the airspace, accounting for various types of air traffic, airspace classifications, and operational procedures.

Understanding that the NAS includes airspace used by general aviation, commercial flights, and other operations is essential, as it highlights the complexity and importance of altitude management and airspace regulation in ensuring safety and efficiency. This knowledge is crucial for anyone operating in the NAS, as it influences flight planning, legal compliance, and air traffic interaction.
