What is the phraseology used for an Aircraft Conflict/Mode C Intruder Alert?

The correct phraseology for an Aircraft Conflict/Mode C Intruder Alert is essential for ensuring that pilots receive a clear and immediate instruction to avoid a potential collision. The correct phrase provides not only a warning but also specific instructions for evasive maneuvering, which is critical in preventing mid-air collisions.

In this context, the phrase includes "TRAFFIC ALERT" followed by the call sign, the position of the aircraft, and instructs the pilot to advise on whether to turn, climb, or descend. The inclusion of directions, such as left or right, and specific altitude or heading, conveys the urgency and precise action required to mitigate the conflict effectively. This structured communication format is vital for the safety of all aircraft involved, as it reduces ambiguity and ensures both the controller and pilot are aligned in their actions.

The other options, while partially correct, do not fully encompass all the necessary elements for clear communication in a conflict situation. Therefore, the choice emphasizing immediate action with detailed instructions stands out as the most appropriate in terms of operational clarity and safety.
