Military and civilian aircraft would be required to use technology that broadcasts and receives real-time location and weather information between planes and air traffic control, similar to how ships use radar to avoid collisions. Military helicopters flying in normal U.S. airspace would have to keep this broadcasting feature on by default, and even helicopters on sensitive missions near Washington, D.C. that are allowed to turn it off would need a safety review to reduce collision risks. By the end of 2031, both military and civilian aircraft already required to broadcast their location would also need to be able to receive that same information from nearby planes. The people who manage air traffic controllers would also face new limits on how long they can supervise without a break, and there would be new rules for quickly informing pilots and others involved when a near-collision happens, plus a review of helicopter flight paths around Reagan National Airport in D.C.
