📖
What is the Runway Visual Range & How does it work?

Runway Visual Range (RVR) is a critical metric for aviation safety, representing the distance a pilot can see down the runway under existing visibility conditions. It is essential for determining whether an aircraft can safely take off or land.

The RVR is typically measured using a transmissometer, which measures the attenuation of light as it passes through the air column between the instrument and the runway surface. The formula to calculate RVR from the transmissometer reading involves converting the transmissometer value into a distance.

RVR = frac{1000}{text{Transmissometer Value}} times 150
RVR = Runway Visual Range in meters
Transmissometer Value = Reading from the transmissometer instrument
