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

• A. 6,000 Feet
• B. 5,000 Feet
• C. 7,000 Feet
• D. 4,500 Feet

Answer: (A)

In RVR SM visibilities, a practical rounding is used: one statute mile is treated as about 6,000 feet. This makes quick mental calculations easier when you’re comparing visibility to standard minima that are often stated in thousands of feet. The exact conversion is 1 SM = 5,280 feet, but for RVR SM contexts the convention is to use 6,000 feet per mile. So the feet equivalent of 1 SM in these visibilities is 6,000 feet. If you needed the precise figure, it would be 5,280 feet, but the common RVR practice uses the 6,000-foot figure.
