When can beacon targets (secondary radar) be used for separation?

• A. When secondary radar is not functioning
• B. When the displacement between the beacon and primary target is within standards
• C. Only with visual confirmation of the targets
• D. When there are no other aircraft in the vicinity

Answer: (B)

The use of beacon targets from secondary radar for separation is applicable when the displacement between the beacon and the primary target is within standards. This means that the radar system can accurately correlate the position of the beacon target with the primary radar target, ensuring that the aircraft are sufficiently separated based on reliable and consistent data. This use of secondary radar is particularly useful in maintaining safe separation between aircraft, as it provides more precise information about the aircraft's identity and position than primary radar alone. When the relationship between the beacon and the primary target meets established standards, air traffic controllers can confidently use that data for separation purposes, knowing that the targets are being accurately tracked. In contrast, the situation where secondary radar is not functioning would prevent its use for separation, and relying solely on visual confirmation or the absence of other aircraft would not provide the necessary systematic approach to ensure safe separation in controlled airspace.
