The director control mode is an integral part of all modern aircraft, i.e. civil, military, transport and even unmanned aerial vehicles. The paper describes the experience of developing, implementing and perfecting the directorial control algorithm in the landing mode as applied to small aircraft DA-42-T and L-410 during flight tests. As the basic algorithm, the algorithm “Deviation allowance” is used. The satellite navigation system, i.e. GPS / GLONASS without differential correction, was selected as the main data source for the approach. This solution allows for semi-automatic landing at an unequipped airfield, but is inferior in accuracy to instrument landing, e.g. ILS, RSBN. According to the results of flight tests, we assessed the accuracy and found that the developed algorithm allows landing in accordance with the 1st category of ICAO.
