Under what visibility condition are special procedures enforced for vehicle operations?

Special procedures for vehicle operations are enforced when the Runway Visual Range (RVR) measures less than 1200 meters. This threshold indicates significantly reduced visibility, which could impair the ability of drivers to see aircraft, signage, and other crucial visual cues essential for safe navigation on the airside. When visibility is low, there is an increased risk of accidents, which necessitates stricter protocols and guidelines to ensure safety for all personnel and operations within the airside environment.

In conditions where RVR is above 1200 meters, the standard operating procedures apply, as visibility is considered adequate for safe vehicle movement. Therefore, special procedures are specifically instituted in low-visibility situations to mitigate risks associated with such conditions. Understanding this policy is essential for anyone operating vehicles in airport environments, as it directly impacts the safety and efficiency of airside operations.
