13) qualified personnel - the trained personnel which had theoretical and practical training and allowed by the operator of the air vehicle, the service provider of ground handling operations or the operator of airfield (the last two concern service providers on anti-icing processing) to accomplishment of certain work type on ice protection of the air vehicle on the earth;

14) sleet - snow which contains enough water to make densely pressed firm snowball from which water will not be squeezed out;

15) the lowest (extreme) operational temperature (LOUT) - the greatest of the following temperatures of use of liquid:

the smallest temperature at which liquid corresponds to aero-dynamic acceptance tests for specific type (high-speed or low-speed) the air vehicle;

freezing temperature of liquid plus the temperature buffer of freezing point (stocked) 10 °C for liquid like I and 7 °C for liquids of types II, III or IV;

16) rain - rainfall of particles of water 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 time interval 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 ice pellets, or visibility in case of snow and drizzle;

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

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

21) the smallest value of viscosity on wing (LOWV) - the smallest value of viscosity of the liquid intended for de-icing or prevention of formation of ice accretion for which acceptable time of protective action is provided;

22) snow - rainfall in the form of ice crystals, often figured in the form of six-pointed asterisks which happen separate or form snow flakes;

23) snowgrains - rainfall of very fine white and opaque particles of ice which are quite flat or extended with diameter less than 1 millimeter (inch 0,04) when snowgrains hit against the firm earth, they do not recoil and do not break.

For determination of time of protective action snow granules, are considered as snow;

25) heavy ice pellets - loss of liquid particles of water which freeze in case of blow about the earth or other open objects. Separate drops of heavy ice pellets are indiscernible, the heavy ice pellets has the measured intensity of more 7,62 of millimeter/hour;

26) freezing point - temperature at which liquid begins to turn into solid substance;

28) time of protective action (further - VZD) (Holdover Time - HOT) - settlement period of time during which deicing fluid will prevent ice formation and ice raid, and also accumulating of snow on the protected (processed) surfaces of the air vehicle in the time spent for the earth prior to running start;

35) check on pollution availability - check of surfaces and components of the air vehicle regarding pollution availability for the purpose of establishment of need of its removal. Operators of the air vehicle determine the procedure of check on pollution availability taking into account features of aircraft design;

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

37) the service provider on anti-icing processing - the organization responsible for carrying out anti-icing processing of air vehicles and/or conducting check after anti-icing processing of air vehicles;

38) ice raid (hoarfrost, crystal hoarfrost) - adjournment of the small white crystals of ice which are formed on the earth or other surfaces. The ice raid is formed by sublimation, that is when water vapor is postponed for surfaces which temperature is equal or below freezing;
