What is the feet equivalent of 1/4 SM in RVR SM visibilities?

• A. 2,400 Feet
• B. 1,600 Feet
• C. 4,000 Feet
• D. 5,000 Feet

Answer: (B)

When pilots convert a fraction of a mile to an RVR value, they use a standard rounded table that maps fractions of a mile to feet used in runway visibility reporting. For quick reference, a quarter-mile visibility is presented as 1,600 feet in this RVR context. That’s why the feet equivalent for 1/4 SM in RVR visibilities is 1,600 feet. The other steps in the table follow the same rounding pattern—1/2 SM becomes 2,400 feet, 3/4 SM becomes 4,000 feet, and 1 SM becomes 5,000 feet. This is a practical convention used to keep readings consistent and easy to communicate on the runway.
