What is RVR 2400 in statute miles?

According to FAA AIM Table 7-1-10, an RVR of 2,400 feet corresponds to 1/2 statute mile (SM) visibility, which is the standard minimum for Category I precision ILS instrument approaches.

What is the difference between RVR and prevailing visibility?

Prevailing visibility is a human or automated observation representing the greatest horizontal visibility across at least half the horizon. RVR is measured specifically along the landing runway corridor and takes regulatory precedence over prevailing visibility for instrument approaches.

FAA AIM Table 7-1-10 Reference:

RVR is measured by transmissometers along the runway touchdown, midpoint, and rollout zones. When reported, RVR takes precedence over prevailing ground visibility for precision approach authorization.

Runway Visual Range (RVR) FAQs

Everything you need to know about cash runway, burn rates, and financial planning.

Runway Visual Range (RVR) is an instrumentally derived measurement of the horizontal distance over which a pilot on the runway centerline can see the runway surface markings, runway edge lights, or centerline lights.
