Pilots test cockpit alert system that could prevent close calls on the runway

The aviation industry is on the cusp of a major breakthrough with the development of a new cockpit alert system that could potentially prevent runway collisions. Honeywell Aerospace’s “Surface Alert System,” or “SURF-A,” is currently in the final testing phase and is designed to detect unauthorized aircraft entering the runway, alerting pilots to potential close calls.

The SURF-A system provides pilots with two aural alerts when a rogue aircraft poses a threat to an authorized plane that is either taking off or landing. The first alert sounds 30 seconds before a potential collision, followed by a second alert 15 seconds before impact. This crucial warning system gives pilots valuable time to react and avoid a dangerous situation.

During a recent test flight, the Honeywell crew demonstrated the effectiveness of the SURF-A system by simulating a close call scenario at an airport. The system successfully alerted the pilot to the presence of another aircraft on the runway, prompting a quick maneuver to avoid a collision. This real-world simulation highlighted the potential life-saving capabilities of the new alert system.

The development of the SURF-A system was prompted by an increase in runway incursions in recent years. The Federal Aviation Administration (FAA) reported 1,664 runway incursions in 2024, with seven incidents involving planes on a collision course. With the FAA reporting 657 runway incursions so far in 2025, the need for improved safety measures is more pressing than ever.

In addition to the SURF-A system, the FAA has been investing in airport infrastructure improvements to enhance safety measures. By adding edge lights, pavement markers, signage, and simplifying taxiway layouts, airports aim to reduce the risk of runway incursions. However, ultimately, pilots remain the last line of defense in preventing such incidents.

Honeywell Aerospace is currently pitching the SURF-A prototype to major airlines and aims to have the system certified by September. If successful, the system could be implemented on commercial flights as early as 2026. With its potential to significantly improve runway safety and prevent close calls, the SURF-A system represents a major advancement in aviation technology.
