Visual Distance Computer

A Visual Distance Computer is a device used in meteorology to measure the visual range or visibility of an object or location. It is classified under the supply class "Meteorological Instruments And Apparatus" and belongs to the supply group "Instruments And Laboratory Equipment."

The Visual Distance Computer typically consists of a series of charts or tables that allow meteorologists to estimate the distance at which an object can be seen under specific weather conditions. These charts take into account factors such as atmospheric conditions, humidity, and the presence of fog, haze, or other obstructions.

By using the Visual Distance Computer, meteorologists can provide accurate information about visibility to pilots, mariners, and other individuals who rely on clear visibility for safe navigation. This instrument is essential in ensuring the safety and efficiency of various transportation systems, as well as in conducting meteorological research and analysis.
