Which of the following is NOT a characteristic of RVR?

The correct choice indicates that RVR, or Runway Visual Range, is not reported in statute miles. Instead, RVR is typically reported in feet or meters and provides a measure of the distance at which a pilot can expect to see the runway environment. This measurement is essential for determining if an aircraft can land safely under current visibility conditions.

Understanding RVR is crucial for pilots and air traffic controllers, as it directly impacts approach and landing protocols. The use of sensors to measure visibility, indicating RVR with a "/" on an approach plate, and its application in determining approach visibility are all integral to how RVR is defined and used in aviation practice. Therefore, identifying that RVR is not reported in statute miles correctly highlights its unique characteristics compared to other visibility measurements.
