Abstract
It is noted that there is a need to develop a methodology for calculating visibility at the earth's surface over flat terrain, taking into account the nature of the underlying surface, based on data from nephelometers installed at automatic road meteorological stations, video cameras and unmanned aerial vehicles in order to improve the efficiency and safety of interregional aviation flights. The importance of solving the problem of restoring horizontal visibility at the earth's surface by using automatic road meteorological stations installed along highways and routes, digital video cameras that allow receiving information received from unmanned aerial vehicles is shown. Calculation methods and results are considered. It is concluded that the method for calculating visibility at the earth's surface allows one to take into account the influence of changes in the relief of flat terrain, the nature of the underlying surface, the time of year, and the spatial and temporal variability of visibility at the earth's surface in various typical synoptic situations. In the case of using digital video cameras, the visibility of landmarks is assessed using optical-electronic visibility range
