What is the role of airport surveillance in air traffic services?

The role of airport surveillance in air traffic services is primarily focused on tracking and managing aircraft within controlled airspace. This function is crucial for ensuring the safe and efficient movement of aircraft, particularly in congested areas near airports and along established flight paths. Airport surveillance systems utilize radar and other technologies to provide real-time information on the position, altitude, and speed of aircraft, allowing air traffic controllers to maintain safe separation between aircraft, provide guidance during takeoff and landing, and manage traffic flows to prevent collisions.

Effective airport surveillance enhances situational awareness for both air traffic controllers and pilots. It ensures that controllers can make informed decisions, issue timely instructions, and react quickly to any potential hazards. This capability is essential for maintaining the safety of flight operations, especially during peak travel times or adverse weather conditions.

In contrast, monitoring weather patterns, serving as a communication link to ground support staff, and ensuring passenger safety during boarding procedures, while important components of airport operations, do not directly pertain to the primary function of airport surveillance within air traffic services.
