Defense Bill Pulls Back on Proposed Military Flight Restrictions in D.C.

Legislation provides exemptions not included in the Senate’s separate aviation safety proposal.

Key Takeaways:

  • The FY2026 National Defense Authorization Act (NDAA) introduces new requirements for military training flights within a 30-mile radius of Washington, D.C., mandating active position broadcasting, though it includes exemptions for national security or if commercial flights are not at risk.
  • These NDAA provisions are less stringent than the proposed ROTOR Act, which was drafted in response to a deadly mid-air collision involving a military helicopter whose ADS-B system was not broadcasting, and would require all civilian and military aircraft to have ADS-B Out and In.
  • The National Transportation Safety Board (NTSB) strongly opposes the NDAA's D.C. airspace subsection, arguing it significantly reduces safety by allowing military training missions "unfettered access" without broadcasting and effectively undoes post-accident safety improvements.

A compromise version of the national defense authorization bill for fiscal year 2026 imposes new requirements on military aircraft operating over the Washington, D.C., metro area but also provides exemptions not present in the U.S. Senate’s proposed ROTOR Act.

The legislation would restrict military training flights from operating within a roughly 30-mile radius of the capital city unless they are actively broadcasting their position. But the secretaries of the departments of Defense and Transportation would have the power to waive the broadcasting requirement over national security concerns, or if commercial flights are judged not to be at risk.
