What is FAROS in Aviation? (Final Approach Runway Occupancy Signal)

Updated: February 24, 2024

Understanding the Final Approach Runway Occupancy Signal (FAROS)

In the world of aviation, safety is paramount. Every aspect of flight operations is meticulously designed and regulated to ensure the well-being of passengers, crew, and aircraft. One crucial element of aviation safety is the final approach runway occupancy signal, commonly known as FAROS. This article will delve into the details of FAROS, its purpose, and its significance in enhancing the safety of air travel.

What is FAROS?

The final approach runway occupancy signal (FAROS) is a visual aid system used at airports to provide an additional layer of safety during the landing phase of an aircraft. It is a specialized lighting system that helps pilots identify the status of a runway and make informed decisions during the final approach.

The primary function of FAROS is to indicate whether the runway is occupied or clear. This information is crucial for pilots as they approach the runway to land. By providing real-time updates on the status of the runway, FAROS helps pilots assess the potential risks and adjust their landing strategy accordingly.

FAROS is typically installed on or near the runway threshold, where it can be easily seen by pilots during the final stages of the approach. The system consists of a series of red and green lights that are strategically positioned to convey specific messages to pilots.

The Importance of FAROS in Aviation Safety

The implementation of FAROS significantly enhances aviation safety by minimizing the risk of runway incursions and collisions during the final approach. By providing clear and concise information about the status of the runway, FAROS allows pilots to make timely decisions and take appropriate actions to avoid any potential hazards.

One of the key advantages of FAROS is its ability to indicate runway occupancy in real-time. This feature is particularly crucial in situations where visibility is limited due to adverse weather conditions or during nighttime operations. By providing a clear visual indication of the runway's status, pilots can effectively determine whether it is safe to continue their approach or initiate a go-around procedure.

Furthermore, FAROS also plays a vital role in reducing the risk of runway incursions, which occur when an aircraft, vehicle, or person enters the protected area of a runway without authorization. By providing a clear indication of runway occupancy, FAROS helps pilots and air traffic controllers identify any potential conflicts and take immediate corrective actions to prevent runway incursions.

How FAROS Works

The final approach runway occupancy signal (FAROS) operates based on a simple yet effective principle. The system uses a combination of red and green lights to convey specific messages to pilots. These lights are positioned in such a way that they form a distinct pattern, allowing pilots to quickly interpret the information being conveyed.

When the runway is clear and safe for landing, the FAROS system displays a steady green light. This indicates to the pilots that they can proceed with their landing without any obstructions or hazards on the runway.

On the other hand, if the runway is occupied or there is a potential hazard, the FAROS system displays a flashing red light. This serves as a warning signal to the pilots, indicating that they should abort their landing and execute a go-around procedure to maintain safety.

In addition to the red and green lights, FAROS may also incorporate other visual elements, such as flashing yellow lights, to indicate specific conditions or warnings. These additional lights can communicate information such as low visibility, reduced runway length, or other temporary conditions that may affect the landing approach.

It is important to note that FAROS is just one component of a comprehensive aviation safety system. Pilots must rely on a combination of visual cues, instruments, and communication with air traffic controllers to ensure a safe landing.

Overall, the implementation of FAROS has been a significant milestone in enhancing aviation safety. It provides pilots with real-time information about the status of the runway, allowing them to make informed decisions during the critical final approach phase. By minimizing the risk of runway incursions and collisions, FAROS plays a vital role in safeguarding the lives of passengers, crew, and aircraft.
