AB - A parallel booster control of transport aircraft controls has been modeled and the positive role of the power reserve for the operation of the structure with permissible operating differences in the pressures of the supply systems has been demonstrated. Introduction Parallel hydraulic drives are typical of large transport aircraft, in which one body (for example, a rudder for height or direction) deviates from several hydraulic boosters. Each of these hydraulic boosters is powered by a separate hydraulic system and, of course, there are acceptable differences in the operation of the drive devices. The control unit that drives these devices is the element through which, in real conditions, the common work is redistributed between the individual hydraulic boosters. Some (faster) work with overload, and others (slower) work with supporting efforts. In the vicinity of the end positions, there are significant differences in the strokes of the individual devices. The theory of hydraulic propulsion of aircraft controls recommends that hydraulic boosters be selected with a 50% power reserve and a 20% speed margin, with possible desynchronization within acceptable limits. In practice, such a stock of all modes and structures cannot always be provided, especially for controls such as movable stabilizers for
