Air traffic management (ATM) is a system that ensures the safe and efficient movement of aircraft in the sky and at airports. It involves coordinating the activities of air traffic controllers, pilots, and ground services to prevent collisions and manage the flow of air traffic. This system uses radar, communication technologies, and flight plans to monitor and guide aircraft during their journey. ATM is crucial for maintaining order in busy airspace, especially in regions with high traffic volumes. It helps optimize flight routes, reduce delays, and minimize fuel consumption, contributing to a more sustainable aviation industry. Effective ATM enhances passenger safety and improves overall travel experiences.
