Which capability is NOT associated with fully instrumented airfield operations?

Fully instrumented airfield operations typically include features and technologies that enhance the efficiency and safety of flight operations in various weather conditions. These operations rely on multiple advanced systems that help in managing air traffic and ensuring safe landings and takeoffs.

Control towers are crucial for directing aircraft movement on the ground and during takeoff and landing phases. They facilitate communication between pilots and air traffic controllers, helping to manage the flow of air traffic effectively.

Airport surveillance radar is used to monitor the positions of aircraft in the vicinity of the airport. This technology ensures that air traffic controllers have real-time information about the air traffic, which is vital for maintaining safety and order.

Precision approach radar aids in guiding aircraft safely to the runway, especially in low-visibility conditions. This technology provides pilots with highly accurate information regarding their approach path, enabling safe landings in adverse weather.

On the other hand, passenger boarding bridges, while essential to airport operations and passenger convenience, do not serve a direct function related to air traffic control or navigation. They facilitate the boarding and disembarking of passengers but are not part of the core systems that support the actual operation of aircraft in a fully instrumented airfield context. Thus, this capability is distinct from those directly involved in flight safety and management
