The random processes analysis of meteorological conditions changes is carried out: the ceiling and visibility range at the enroute alternates Nizhnevartovsk and Bratsk, selected when planning Russian airlines Far Eastern flights. The random processes analysis is based on the meteorological aerodrome half-hour observations database in 2017 and 2018 for the direct and return flights periods to the Russian Far East. Based on the analysis, the ceiling and visibility regression forecast on direct and return flights, necessary to determine the enroute alternate planning minima, is made. The existing methods shortcomings for the enroute alternate planning minima determining used in the Russian Federation, the United States, the European Union and other countries are indicated. A new enroute alternate planning minima determination method based on a meteorological condition changes regression forecast is proposed. The new method also can be used for North Atlantic, Pacific and other long-range routes and helps the airlines increase their flights regularity by increasing the amount of enroute alternate available days in year. The ceiling and visibility increments calculated using the new method must be used regardless of the enroute alternate area of operation radius.
