What authority do flight service specialists have regarding ground traffic?

Flight service specialists play a critical role in managing ground traffic at airports, particularly in relation to vehicles. They are responsible for providing necessary instructions to vehicles operating on the airport movement area, which includes taxiways and runways, to ensure safe movements around the airport environment.

The authority to issue instructions specifically to vehicles is vital for maintaining safety and efficiency in airport operations. By guiding ground vehicles, flight service specialists help prevent conflicts between aircraft and ground traffic, thereby reducing the risk of incidents. It's important to note that their focus is primarily on the vehicles and not directly on aircraft, as those communications are typically handled by air traffic control personnel who are responsible for the overall management of air traffic operations.

This specialization allows flight service specialists to ensure that ground vehicles follow established protocols, remain clear of active runways, and adhere to the correct taxiing routes, ultimately contributing to safe airport operations.
