What is the purpose of flight data blocks in air traffic control?

The purpose of flight data blocks in air traffic control is to assist controllers in monitoring and separating aircraft effectively. Flight data blocks display essential information related to each aircraft, such as its identification, altitude, speed, heading, and any pertinent flight information. This real-time data is crucial for controllers to maintain situational awareness, ensuring safe and efficient air traffic management.

By having access to this information, controllers can make informed decisions about aircraft spacing and routing. This capability is vital in busy airspace where multiple aircraft are operating simultaneously, allowing for timely updates and adjustments to prevent conflicts and maintain safety.

While the other options touch on important aspects of air traffic control, they do not encapsulate the primary function of flight data blocks. For example, historical data and system alerts serve different purposes and are not the primary focus of flight data blocks.
