Question

What would R13/1500V2400FT/D indicate on a METAR (RVR)?

a. Runway visual range 1300 meters, Variable between 1500 and 2400 feet, Daytime
b. Rainfall rate 13 mm per hour, Visibility 1500 to 2400 feet, Decreasing
c. Rotorcraft visibility 13 miles, Variable between 1500 and 2400 feet, During daylight
d. Runway visual range 1300 meters, Variable between 1500 and 2400 feet, Decreasing

Answer 1

The notation R13/1500V2400FT/D in a METAR report describes the runway visual range as 1300 meters, with variable visibility between 1500 and 2400 feet, and this visibility is decreasing.

Step-by-step explanation:

The term R13/1500V2400FT/D found in a METAR report, which indicates runway visual range, can be broken down as follows:

• R denotes that it pertains to the runway.
• 13 indicates the runway visual range is 1300 meters.
• 1500V2400FT shows that the visual range is variable, with a variability between 1500 and 2400 feet.
• The /D at the end stands for decreasing, meaning that the visual range is forecasted to decrease.

Therefore, the correct interpretation of R13/1500V2400FT/D is: Runway visual range is 1300 meters, variable between 1500 and 2400 feet, and decreasing.
