What happens if a vehicle passes an aircraft that has its anti-collision lights on?

The correct answer indicates that passing an aircraft with its anti-collision lights on is allowed as long as the vehicle maintains a distance of at least 10 meters away from the aircraft. This distance is important because anti-collision lights are an indication that the aircraft is either preparing for takeoff, landing, or taxiing, and maintaining a safe distance ensures the safety of both the ground vehicle and the aircraft.

Thus, as long as the vehicle stays at least 10 meters away, it is permissible to pass, adhering to airport regulations and safety protocols designed to protect all personnel and equipment in the airside area. It's a critical standard in airport operations to ensure that ground vehicles do not interfere with the aircraft's movement or safety procedures.

In contrast, the other options suggest consequences or rules that are not in line with standard procedures. A fine may not apply if the vehicle is following the distance regulation, and losing a permit would typically result from more serious violations than simply passing at the correct distance. Additionally, while it may seem reasonable to consider prohibiting any movement near an aircraft with its lights on, the established practice allows for specific safe passing protocols when the proper distance is observed.
