Model of Complex Aviation and Climatic Indicator for Flight Planning on Local Airlines

Abstract

The purpose is to improve the provided climate information by constructing a model of a complex aviation and climatic indicator, determined by combinations of cloud base height and fl ight visual range. Materials and methods. Source materials are the author's own original developments. The construction of the model is based on the theory of non-horizontal visibility of objects (landmarks) on the earth's surface and the experience of air navigation. The eff ectiveness of the model was tested by surveying fl ight personnel in 2023. Results and discussion. It is shown that the identifi cation of the slant fl ight visibility range with the values of the meteorological visibility range under low clouds does not allow an objective assessment of the possibility of performing fl ights on local airlines. In haze, the values of the inclined fl ight visibility range amounted to 40 % of the meteorological visibility range in type I, 55 % in type II, 83 % in type III, and 90 % in type IV of the distribution of horizontal visibility with height. Conclusions. The use of a complex aviation and climate indicator for planning fl ights on local airlines under low clouds and subsequent correction of the possibility of their implementation by changing the altitude and speed of the aircraft, the heading angle of observation will allow air traffi c management authorities to make weather-dependent decisions through the use of intelligent meteorological system.
