The purpose of this legislation is to enhance aviation safety by advancing the deployment of a new technology called the Airborne Collision Avoidance System-X (ACAS-X). The goal is to create a comprehensive action plan that outlines how this technology will be integrated into the national airspace system, ultimately reducing the risk of mid-air collisions. Key provisions of the legislation require the Administrator of the Federal Aviation Administration (FAA) to submit an action plan to Congress within 180 days of the law being enacted.
