Many new and existing aircraft types are today able to receive the update, but some, including the CRJ regional aircraft involved in the January 2025 accident near Washington, D.C. that prompted the legislation, are not.

The ROTOR Act, which will be voted on by the Senate Commerce Committee on Oct. 21, is the first major proposed piece of legislation to specifically address safety issues identified in the aftermath of the D.C. crash, most notably the lack of ADS-B In functionality on the CRJ and the U.S. Army Black Hawk’s ability to fly in congested airspace without ADS-B Out enabled.
