This bill establishes a new requirement for all aircraft, including military, operating within Class B airspace in the national airspace system. Upon enactment, these aircraft must have ADS-B In and ADS-B Out equipment installed, activated, and continuously receiving whenever they are taxiing or in flight, meeting specified performance standards. A significant provision of the bill explicitly prohibits the Secretary of Transportation or the Administrator from implementing any regulations that would exempt aircraft from these mandatory ADS-B requirements. Furthermore, it repeals Section 1046 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019, thereby eliminating a previous exemption for Department of Defense aircraft concerning the installation of automatic dependent surveillance-broadcast equipment.
