What A/C lights must be off while on the boat due to potential distraction?

The correct response to this question is the anti-collision lights. These lights are designed to make the aircraft more visible to other aircraft, especially in crowded or low-visibility environments. However, when on the boat, having the anti-collision lights on can create a distraction for both the crew on board and nearby personnel.

It’s important in a confined space, like on a ship, to minimize potential distractions to ensure safety and operational efficiency. The anti-collision lights are quite bright and can be disorienting, thus they are turned off while on the boat to maintain a clear line of sight and avoid unnecessary distraction for those involved in flight deck operations.

While other lights such as position lights, strobe lights, and runway recognition lights play roles in aircraft visibility and safety, they are not specifically designated as distracting in this context. This ensures the crew can focus on their tasks without the interference that anti-collision lights may bring during critical operations on the flight deck of the ship.
