A bill to require aircraft operating in Class B airspace in the national airspace system to install and operate ADS-B In and ADS-B Out equipment, and for other purposes.

# Summary of S 1706 **What the Bill Would Do** This bill would require all aircraft flying in Class B airspace—the most congested and heavily-controlled airspace around major U.S. airports—to be equipped with ADS-B (Automatic Dependent Surveillance-Broadcast) technology. ADS-B In and Out are systems that allow aircraft to automatically transmit their location and receive real-time information about other nearby aircraft. The bill aims to improve aviation safety and air traffic control efficiency in busy airspace. **Who It Affects** The requirement would apply to all pilots and aircraft owners who operate in Class B airspace, which surrounds major metropolitan airports like those in New York, Los Angeles, Chicago, and other major cities.

This includes both commercial airlines and smaller general aviation aircraft. The bill could result in significant costs for aircraft owners who need to install the required equipment. **Current Status** S 1706 is currently in committee and has not yet been voted on by the full Senate. No action has been taken since its introduction in the 119th Congress. The bill was sponsored by Senator Jerry Moran, a Republican from Kansas.
