the smallest temperature at which liquid corresponds to aerodynamic acceptance tests for specific type (high-speed or low-speed) the aircraft;

16) rain - rainfall of water particles or in the form of drops diameter of more 0,5 of millimeter, or in the form of smaller drops which are rather removed from each other unlike drizzle;

17) intensity of rainfall – indicator of amount of precipitation, dropped out for single interval of time which is classified as weak, average or strong. Intensity is determined taking into account type of specific rainfall on basis or regulations of loss of rain and sleet, or visibility in case of snow and drizzle;

18) high humidity - atmospheric conditions when the amount of moisture in air is close to saturation;

19) visible moisture - education on the surface of the aircraft, covering of rulyozhny paths and landing strips of film of visible moisture in conditions when under the influence of fog, rain, snow, sleet, high humidity (condensation on surfaces) and ice crystals on their surface moisture accumulates;

Operators of the aircraft determine the procedure of check on pollution availability taking into account features of design of the aircraft;

36) transparent ice – ice or ice raid on the cold surface of the aircraft which is on the earth which can be formed in the presence of visible moisture or high humidity even at temperatures of air from -2 °C to +15 °C if the design of the aircraft has temperature of 0 °C or below;
