Which of the following is considered a hazard that should be reported by AVOP holders?

The choice of unattended vehicles in authorized areas is indeed a significant hazard that should be reported by AVOP holders. Unattended vehicles can obstruct operational activities, interfere with the movement of other vehicles or aircraft, and pose safety risks for personnel on the airside. These vehicles can block vital pathways, affecting ground support operations and creating potential dangerous situations. Reporting such hazards ensures that they are addressed promptly to maintain safety standards and operational efficiency.

In contrast, while minor vehicle scratches may be a concern for maintenance, they do not typically pose immediate safety risks to operations. Potholes in the pavement are certainly a safety concern, but they are usually managed through regular maintenance processes and may not require immediate reporting by AVOP holders unless they pose an urgent hazard. Inconsistent paint on airside markings can lead to confusion but is generally addressed through routine inspections and maintenance by the appropriate authority and would not typically be the responsibility of individual AVOP holders to report.
