Abstract

A method for estimation of systematic errors of onboard measurement of angle of attack and sliding angle of an aircraft in the course of flight tests using high precision velocity measurements performed by a satellite navigation system is proposed. The main specific feature of the proposed method is that for providing compatibility of measurements of angle of attack and sliding angle sensors and data of the satellite navigation system the identification of wind velocity on the processed leg is used. The operation of the proposed method and the correctness of applied assumptions are proved by processing large amounts of experimental data obtained in the course of flight tests.
