As is generally known, the most crucial phases of any flight are take-off and landing. Many factors may affect these two phases, not least the prevailing weather conditions on the runway. When an aircraft lands in less-than-ideal weather conditions, one of the most important factors will be runway visibility. Not so long ago, the traditional method of taking runway visual range (RVR) readings was via human observation. The observer would enter the runway in use, or stand within spe...
