When is RVOP in effect for the entire airfield?

The correct understanding of the conditions under which the Runway Visual Range (RVR) Operational Plan (RVOP) is in effect for the entire airfield pertains specifically to visibility measures. RVOP is a safety protocol that helps manage operations when visibility is limited.

In this context, RVOP is usually mandated when an aircraft's performance can be compromised due to reduced visibility conditions. When RVR readings are between 2600 and 1200 feet, it indicates a state of lowered visibility in which multiple factors affect the operation of aircraft on the airfield. This range signifies that while operations can continue, specific enhanced procedures and guidelines are necessary to ensure safety and compliance with aviation standards.

When RVR is at the extremes, such as below 1200 feet, rules become stricter, and one would typically transition to more restrictive operating protocols, which could include limiting operations significantly or considering closure of the airfield for certain operations. RVR values at 1000 or below would necessitate an operational response that goes beyond the RVOP's typical conditions, hence the focus on the 2600 to 1200 range for RVOP activation across the entire airfield.

Therefore, the safe operational latitude provided between the RVR conditions at 260
