What must aircrews do when executing visual circling maneuvers during night operations?

In the context of executing visual circling maneuvers during night operations, the correct answer emphasizes the importance of adhering to instrument flight rules for safety and precision. When flying at night, visibility is often reduced, and it can be challenging to maintain situational awareness. By focusing on flying only the instrument portion of the approach and executing a missed approach at the specified missed approach point, aircrews can ensure a safe transition to a go-around if they do not have visual references necessary to continue safely to landing.

This procedure aligns with safety protocols which dictate that crews must prioritize navigational aids to maintain control of the aircraft, especially in low visibility conditions. It reinforces the necessity of relying on instruments when visual cues are unreliable or insufficient, enhancing overall operational safety during night flying scenarios.
