What RVR reading indicates that LVOP is in effect for the entire airfield?

When considering RVR (Runway Visual Range) readings and their implications for operations at the airport, a reading of less than 1200 RVR indicates that Limited Visibility Operations Procedures (LVOP) are in effect for the entire airfield.

This threshold is critical because it signifies that visibility conditions are reduced to a point where standard operations may be compromised. Under LVOP, specific protocols are implemented to ensure safety, including restrictions on aircraft movements and enhanced communication among ground personnel. The adjustment to operations in such conditions aims to mitigate risks associated with reduced visibility while ensuring continued safe airport functioning.

Understanding this threshold is crucial for operators on the airside to ensure compliance with safety regulations, adjust their operations accordingly, and maintain awareness of the conditions affecting their movements.
