4500 RVR equals how many statute miles?

To determine how many statute miles 4500 RVR (Runway Visual Range) equals, it's important to understand the conversion between RVR, typically expressed in feet, and statute miles.

RVR is often expressed in feet, with 4500 RVR indicating a visibility distance of 4500 feet. To convert this to statute miles, you can use the conversion factor that 1 statute mile is equal to 5280 feet. When you divide 4500 feet by 5280 feet per statute mile, the result is approximately 0.85 statute miles, which corresponds closely to 7/8 of a statute mile.

This conversion highlights the correct answer as 7/8 statute miles, allowing pilots to understand visibility limitations when operating under instrument flight rules.
