Is the latest weather report from the control tower with specified RVR value controlling for arrivals and departures?

The latest weather report from the control tower, which includes the specified Runway Visual Range (RVR) value, is considered controlling for both arrivals and departures. This is crucial because RVR provides pilots and air traffic controllers with a standardized measurement of how far one can see down the runway, which directly influences aircraft operations.

When RVR values are reported, they inform decision-making regarding safe landing and takeoff visibility. An updated weather report ensures that all arriving and departing aircraft have the current conditions considered when executing flight operations. This comprehensive approach helps maintain safety and efficiency at the airport, as pilots rely on such data to determine whether it is safe to proceed with their flight operations.

Understanding that RVR values are applicable to the entire range of flight operations reinforces the importance of adhering to the latest reports to mitigate risks and maintain a high level of safety in aviation operations. This is why the assertion that the latest weather report is always controlling is accurate.
