Multiple Choice

RVR values are stated in which unit?

Runway Visual Range tells you how far along the runway a pilot can see the runway environment, and in the United States it is reported in feet. This convention matches other aviation distance measurements used in U.S. weather reports, so you’ll commonly see RVR values written with a suffix like FT (for feet), for example 2400FT. While many other countries report RVR in meters, the FAA practice for this context uses feet, making it the correct choice here.
