When using automated handoff functions, which targets should be verified?

The correct response focuses on the verification of primary and non-discrete targets during automated handoff functions. In air traffic control, primary targets refer to aircraft that are detected by radar returning a signal, while non-discrete targets are those that do not have an assigned transponder code or may not be actively responding to radar interrogation.

Verifying these types of targets is essential because they represent the aircraft's position and movement, which must be accurately tracked for safe navigation and separation. Ensuring the integrity of both primary and non-discrete targets during automated handoff procedures helps prevent misunderstandings that could lead to airspace conflicts or loss of situational awareness.

The other choices represent groups of targets that may not encompass the full scope of the verification process required for automated handoff functions. Focusing solely on airborne traffic or specific types such as incoming or chartered flights would not account for all relevant aircraft in the airspace, potentially leading to gaps in monitoring and management.
