The traditional air data systems are based on the aerodynamic and aerometric method employing the fixed for the incoming air flow vane sensors of aerodynamic angles, receivers of the air pressures and braking temperatures, which worsen the aerodynamics, cause errors, depending on the parameters of the flight and environment, and reduce reliability of the system in real operating conditions. Ideology of construction, the algorithms of information processing of the air data system of the aircraft with the fixed included receiver of flow are based on the fixed ion-label sensor of aerodynamic angle and true airspeed, which realizes the kinematic measurement method with the accuracy of measurement not depending on the state of the environment. For the simultaneous measurements of all the air signals of the aircraft the onboard receiving electrodes of the ion-label sensor set the vent for collection of the static pressure of the incoming air flow. A functional diagram of the air data system with fixed included receiver of the flow and algorithms for calculation of the altitude-speed flight parameters of the aircraft is presented. The methodology and estimation of the errors of the system measuring channels, which meet the modern requirements and determine prospects for application of the system on the aircraft of various classes and purposes, are also presented.
