Abstract. It is noted that measuring the air parameters of airplanes and other aircrafts movement is necessary for solving control problems and ensure safety of traffic within the atmosphere. The features of widely used systems for measuring air parameters with receivers and sensors of incoming air flow parameters distributed throughout the fuselage are considered. Pneumatic lines and electrical cables that connect these receivers and sensors to an on-board computer generating system output signals, complicate the design and increase the system weight and cost. Receivers and sensors protruding beyond the fuselage skin disrupt the aerodynamics of the aircraft and increase its trajectory visibility. The systems being developed for measuring air parameters using vortex, ion-tag and ultrasonic methods for monitoring the oncoming flow and built on the basis of one (integrated) multifunctional flow receiver, also do not eliminate all of these shortcomings. The principles of constructing a system for measuring the air parameters of an aircraft's movement with an integrated fuselage flow receiver with built-in primary information converters and a system computer are formulated. Analytical models of primary informative signals, algorithms for their processing and generation of system output signals are developed. The competitive advantages and scope of application of the system under consideration are discussed.
