FAA seeks fixes to collision warning devices

FAA officials are proposing fixes to midair-collision warning devices installed on what they say are nearly 9,000 U.S aircraft, after uncovering a safety problem during a test flight, according to a report in The Wall Street Journal. The proposed Airworthiness Directive is the result of a flight test over a busy airport’s airspace, which found that the traffic alert and collision avoidance systems manufactured by Aviation Communication & Surveillance Systems LLC, failed to properly keep track of all nearby planes. The agency said one aircraft disappeared for at least 40 seconds from cockpit displays, which “could lead to possible loss of separation of air traffic and possible mid-air collisions.” Read the full report here.
