What is required for effective air traffic management?

Accurate and timely flight data is essential for effective air traffic management because it allows Air Traffic Controllers (ATCs) to make informed decisions regarding the safe separation and routing of aircraft. When flight data is current and precise, controllers can maintain situational awareness and respond promptly to changing conditions, such as aircraft movements, weather changes, or emergencies. This data includes information about aircraft positions, altitudes, speeds, and flight plans, which is crucial for coordinating the actions of multiple aircraft within a busy airspace.

Having up-to-date flight data helps promote safety, efficiency, and operational effectiveness in air traffic management. It enables ATCs to optimize traffic flows, reduce delays, and ensure that aircraft remain at safe distances from one another during all phases of flight. This emphasis on the importance of accurate and timely information makes this choice the optimal answer in the context of effective air traffic management.
