To direct the Secretary of Defense to test and certify each automatic dependent surveillance-broadcast out transponder system on a Department of Defense aircraft that is operated in United States airspace, and for other purposes

airspace. **Who it affects:** - Department of Defense and military aviation operations - Federal Aviation Administration (air traffic control) - Civilian aircraft and commercial aviation sharing U.S. airspace - Air traffic safety overall **What would change:** ADS-B Out systems automatically broadcast an aircraft's location, speed, and other flight data to air traffic control and nearby aircraft. Currently, civilian aircraft must have certified ADS-B systems, but military aircraft may use different or uncertified equipment. This bill would require military aircraft to meet the same testing and certification standards, potentially improving air traffic safety and coordination between military and civilian aviation in shared airspace. **Current status:** The bill is in congressional committee for review and has not yet been voted on.
