FAA mandates ADS-B out for all DCA Class B airspace operators after safety concerns

The U.S. Senate Committee on Commerce, Science, and Transportation convened on March 27, 2025, to discuss the National Transportation Safety Board's (NTSB) preliminary report on the recent midair collision near Ronald Reagan Washington National Airport (DCA). The meeting focused on critical safety concerns regarding air traffic management and the use of Automatic Dependent Surveillance-Broadcast (ADSB) technology.

A significant point of discussion was the FAA's previous allowance for certain aircraft to operate without ADSB, which was highlighted as a potential factor contributing to the collision. Brigadier General testimony indicated that the Army's policy prohibited routine use of ADSB, raising questions about the FAA's oversight and decision-making processes. Senators expressed frustration over the FAA's apparent lack of awareness regarding the safety implications of allowing flights to operate within dangerously close proximity without necessary signaling measures.

The acting FAA administrator confirmed that, effective immediately, all aircraft operating in DCA Class B airspace would be required to have ADSB turned on, except in very limited circumstances. This decision aims to enhance safety and prevent mixed traffic scenarios involving helicopters and fixed-wing aircraft. The administrator acknowledged concerns about other agencies, including military and law enforcement, operating under exemptions and assured that new restrictions would be communicated to ensure compliance.

Senators emphasized the importance of adhering to NTSB recommendations and criticized the FAA for not implementing necessary safety measures sooner. They highlighted the relatively low cost of equipping aircraft with ADSB technology compared to the potential loss of life, urging the FAA to prioritize safety over exemptions.

The meeting concluded with a commitment to improve oversight and communication among agencies to prevent future incidents. The discussions underscored the urgent need for robust safety protocols in the National Capital Region's airspace, reflecting a collective determination to learn from the tragedy and enhance aviation safety standards.
