Answer :
Final answer:
Runway Visual Range (RVR) is obtained by one set of instruments at the threshold of the runway, which measures the visibility along the runway using technologies like transmissometers or forward scatter meters.
Explanation:
The correct answer is C. One set of instruments at the threshold of the runway.
The Runway Visual Range (RVR) is a measure of the horizontal distance an observer can see down the runway from a fixed position near the landing threshold of the runway. To obtain the RVR, one set of instruments is installed at the threshold of the runway, which measures the visibility along the runway.
These instruments use technologies like transmissometers or forward scatter meters to assess the visibility and provide accurate information for pilots and air traffic controllers to ensure safe landing and takeoff operations. The information from the local Meteorological Office may provide additional weather-related data, but it is not specifically used to obtain the RVR.
