What does RVR stand for in aviation management?

RVR stands for Runway Visual Range, which is a critical measurement in aviation that indicates the distance over which a pilot can see the runway surface markings and lights. It is particularly important during low visibility conditions, such as fog or heavy rain, as it helps assess whether it is safe for an aircraft to land or take off. RVR is typically determined using specific equipment that measures horizontal visibility and communicates this information to pilots and air traffic control.

Understanding RVR is essential for ensuring safety in airport operations, especially when deciding on landing and takeoff protocols. This measurement plays a key role in the decision-making process for both pilots and air traffic controllers, ensuring that all stakeholders are informed about the current visibility conditions on the runway.

Other options do not accurately reflect aviation terminology related to visual range, making them less relevant in the context of air traffic management and safety decisions.
