In what situation should you use your headlights on the airside?

Using your headlights during low visibility situations is crucial for safety on the airside. In conditions such as fog, rain, snow, or darkness, visibility can be severely reduced, making it harder for both drivers and pedestrians to see each other. Turning on your headlights not only illuminates the area around your vehicle but also makes your vehicle more visible to others, thereby reducing the risk of accidents. Proper use of headlights is an essential part of maintaining safety protocols in areas where aircraft and ground vehicles operate closely together.

The applications of the other options do not prioritize safety in the same way. During daylight hours, it is typically not necessary to use headlights unless visibility is compromised. Using headlights only when backing up limits their potential benefit, as low visibility could occur in other scenarios that would still necessitate their use. Parking on the apron does not require headlights, especially if other safety measures are in place, making this option less relevant in terms of promoting visibility and safety.
