Which of the following visibility values corresponds to RVR 4500?

Which of the following visibility values corresponds to RVR 4500?

• A. 1 SM Visibility
• B. 1-1/4 SM Visibility
• C. 5/8 SM Visibility
• D. 7/8 SM Visibility

Answer: (D)

RVR, or Runway Visual Range, is a measurement used to determine the distance a pilot can see down the runway, which is crucial in assessing landing and takeoff conditions. When translating RVR values to statutory visibility for flight operations, it's important to understand the conversions between RVR in feet and statute miles. In this case, RVR 4500 feet needs to be converted into statute miles for comparison with the visibility options provided. Since there are 5280 feet in a statute mile, RVR 4500 feet converts to approximately 0.85 statute miles. The nearest visibility value to this RVR measurement is 7/8 statute miles, which is equal to approximately 0.875 statute miles. This aligns with the appropriate visibility conditions for operations under IFR, particularly during approach and landing. In contrast, options such as 1 SM or 1-1/4 SM exceed the converted value, making them incompatible with RVR 4500. Thus, the correct choice is the one that best corresponds to the converted visibility value of RVR 4500 feet.
