Annotation: The article deals with the problems of designing and development of information models system for data support of activities of air traffic operator in automated control system. The generalized analysis of operator’s activities is conducted, the assessment of time expenditure for the fulfillment of different actions, concerned with the analysis of information models, is described, and the set of standard actions under different conditions of current air environment is selected. The selection of standard actions of the operator allows to form the algorithms or scenerios of his behavior, what, in its turn, serves as a basis for the engineering of information models. The application of intellectual information technologies enables to solve the task of current situation recognition and implement the synthesis and control procedure of information models. The use of operator’s behavior scenario can improve the quality of data support engineering and provide the increase of operator’s activities efficiency.
