What does a flashing Final Approach Occupancy Signal (FAROS) indicate?

A flashing Final Approach Occupancy Signal (FAROS) indicates a go-around procedure for pilots approaching an airport. This signal is used primarily to communicate to pilots that it is not safe to land due to potential obstructions or other aircraft on the runway. The flashing light serves as a clear and urgent warning that the landing should be aborted and the aircraft should circle back or reroute, ensuring the safety of all involved. This system is vital for maintaining safe traffic management at airports, especially during busy flight operations or unexpected situations. Understanding this signal is crucial for pilots to respond appropriately and ensure safe landings.
