Which data block type appears east of the target?

The correct answer is that all data block types can appear to the east of the target in the context of air traffic control and radar display systems. Each type of data block provides important information about aircraft and traffic management, and their positioning in relation to the target can vary based on the selected display settings, the specific control environments, and the operational procedures in place at any given time.

In radar systems, the data blocks serve different purposes, such as providing information on the aircraft's identity, altitude, speed, and other parameters. Although each type of data block—Enhanced Limited, Paired Limited, and Unpaired Limited—has its own specific characteristics, all can be displayed in various orientations, including east of the target, depending on how the display is configured and how the controllers choose to view the radar.

The Enhanced Limited Data Block typically contains more detailed information, while the Paired and Unpaired Limited Data Blocks contain varying degrees of operational data. Since they are all integrated into radar displays, it is possible for all types of blocks to be depicted to the east of any target on the screen based on the flight patterns and the specific needs of air traffic control operations.
