US Airlines Adopt ADS-B In Technology to Prevent Collisions

U.S. airlines are moving to install Automatic Dependent Surveillance-Broadcast In (ADS-B In) technology to prevent midair collisions. The system allows pilots to receive real-time traffic broadcasts in the cockpit, a significant upgrade from current mandates that only require ADS-B Out for transmitting aircraft positions.

This shift follows a January 2025 crash between a U.S. Army Black Hawk helicopter and an American Airlines regional jet that killed 67 people. While the Air Line Pilots Association supports a congressional mandate for the technology, some carriers remain hesitant to invest until legislation is finalized to avoid redundant costs.

Acron Technologies has already equipped the single-aisle Airbus fleet of American Airlines and is currently in discussions with most other U.S. carriers. United Airlines has confirmed that its new widebody deliveries will include the system and is coordinating with the Federal Aviation Administration to expand the service to other aircraft types.
