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.

This bill requires all aircraft (including military aircraft) operating in Class B airspace - typically around major airports - to install and activate ADS-B In and ADS-B Out equipment starting upon the bill's enactment. ADS-B Out broadcasts an aircraft's position and speed data to ground systems and other aircraft, while ADS-B In receives similar data for pilots. The bill repeals a prior exemption that allowed military aircraft to skip this requirement under the 2019 Defense Act. It directly affects pilots, airlines, and military operators flying in high-traffic airspace by mandating this technology for improved air traffic surveillance and safety.
