Innovative Cockpit Alert System Aims to Prevent Runway Collisions

KANSAS CITY, Mo. – Engineers are in the crucial final testing phase of a groundbreaking cockpit alert system designed to avert runway close calls. Developed by Honeywell Aerospace, the new technology, known as the Surface Alert System or SURF-A, promises to enhance safety during takeoffs and landings.

This advanced system utilizes sophisticated sensors to detect unauthorized aircraft on runways. When a plane that has been cleared for takeoff or landing encounters an intruding aircraft, SURF-A issues two distinct aural alerts to the pilots. The first alert activates 30 seconds prior to a potential collision, while the second alarm sounds just 15 seconds before impact.

Doug Rybczynski, a Honeywell Test Pilot, emphasized the importance of these time intervals. He explained that while 15 to 30 seconds may seem minimal, it provides pilots with a critical window given the rapid nature of aviation operations. Rybczynski noted that, at high speeds, even a short amount of time can make a significant difference.

The alert system employs an automated voice message that twice declares, “traffic on runway,” helping to ensure pilots are aware of the imminent danger.

Real-Life Simulation and Testing

On a recent test flight, the Honeywell team piloted a plane from Kansas City Downtown Airport to Topeka, Kansas. During the approach, they parked a smaller Gulfstream aircraft at the end of the runway to trigger the SURF-A alert system. Upon receiving the warnings, the pilot executed a
