In recent years, there has been a rapid development of unmanned aerial vehicles, and one of the classes of these aircraft are Optionally Piloted Vehicles (OPV). This means that manually piloting aircraft by the pilot is adapted to the remote control by an operator in a flight management ground-based center, and to exercise autonomous, automatically controlled flight. For remotely controlled OPV particularly important are delays in the transmission of control signals and the aircraft controllability degradation in case of partial damage of the on-board control system. Influence to the quality of the plane control is taking into consideration. Handling qualities of OPV are important from operator point of view. These proprieties influence to operational performance and flight safety. Specified areas limits of control system degradation are calculated, and a method of partial compensation of the impact of disability is presented. The model-following method was used for control augmentation system parameters calculations. That main idea of this method is that OPV reaction on the operator steering signals should be similar - almost the same - as reaction of the "ideal" remote controlled aircraft. Article is illustrated with an example of a calculation relate to a medium-sized, optionally piloted aircraft MP-02A.
