What does RVR stand for in airport operations?

RVR stands for Runway Visual Range, which is a critical measurement in airport operations, particularly concerning visibility conditions for pilots during landing and takeoff. RVR indicates the distance a pilot can see down the runway, which is crucial for ensuring that the aircraft can safely navigate the runway during poor visibility conditions, such as fog or heavy rain.

This measurement is vital for determining whether it is safe for an aircraft to land or take off, as it helps establish the appropriate weather minimums for runway operations. Accurate RVR readings enable air traffic controllers and pilots to make informed decisions regarding flight status and operations involving reduced visibility.

In contrast, the other options do not represent established terms used in aviation. For example, Runway Vehicle Regulation does not pertain to visibility; similarly, Remote Vehicle Reporting and Runway Visibility Regulation either misinterpret existing terminologies or do not specifically refer to visibility measurement on runways. Thus, the recognition that RVR specifically means Runway Visual Range is essential for understanding airport operation protocols and ensuring safety during adverse weather conditions.
