What is the feet equivalent of 3/4 SM in RVR SM visibilities?

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

Answer: (A)

Converting miles to feet is the key idea here. One statute mile equals 5,280 feet. So 3/4 of a mile is 0.75 × 5,280 = 3,960 feet. In aviation, visibility figures are typically given in feet and rounded to the nearest hundred, so 3,960 rounds to 4,000 feet. Therefore, the feet equivalent is 4,000 feet. The other options correspond to different fractional miles (for example, 2,400 ft is about 0.455 SM, 1,600 ft is about 0.303 SM, and 5,000 ft is about 0.946 SM).
