What does the Enhanced Limited Data Block (ELDB) display?

The Enhanced Limited Data Block (ELDB) is designed to present essential information to air traffic controllers in a streamlined format. It primarily displays the aircraft's callsign and its assigned altitude, which are critical for maintaining situational awareness and ensuring proper separation and safety in controlled airspace.

The callsign helps controllers easily identify aircraft, while the assigned altitude is crucial for managing vertical separation between aircraft. This format is particularly valuable in busy air traffic environments where quick, clear communication is required.

Other options such as flight plan route, departure and arrival times, or pilot and crew information are not included in the ELDB. Instead, they are typically found in different data formats or blocks offered within air traffic control systems, emphasizing the ELDB's focus on the most immediate and relevant data for flight monitoring and control.
