Abstract. The necessity of creating a system of air signals of an airplane with one fixed non-protruding re-ceiver of incoming air flow is substantiated. Features of the airborne signal system of an airplane with a fixed non-protruding receiver of the incoming air flow, which are based on an ion-tagged aerodynamic angle sensor and true airspeed with a static pressure receiver hole on its streamlined surface, are revealed. Algorithms for processing information in the measuring channels of the system are presented, methodical static errors of the system for measuring air signals of an aircraft with a fixed non-protruding receiver of the air flow and technologies for their reduction are evaluated, the causes of such errors are analyzed.

Keywords: air signals, fixed non-protruding flow receiver, ion-tagged sensor, receiver hole, static pressure, algorithms, methodical static errors
