    Opis:
    In the modern world, scientific and practical ergodesign activity on the development and use of drones, the concept of "human factor" is becoming more and more important. It is one of the main studies in improving the safety, efficiency and comfort of the "man - unmanned aerial vehicle" system operation. The most promising research is aimed at the application and development of new approaches to the evaluation of algorithms for unmanned aircraft maintenance and the organization of their operators` activities. The system of unmanned aerial vehicles ergodesign quality indicators developed and presented in a tabular form reflects practically all design and ergonomic properties of modern unmanned aerial systems. It is based on the existing normative documentation inUkrainedeveloped by the authors, harmonized with international and European standards. It allows the analysis and evaluation of unmanned aerial vehicles in order to take into account consumer interests at the beginning of their design reducing the assimilation time of products and preventing irrational production costs. The results of such an analysis underlie the development of technical documentation, standards, and specifications. They should be taken into account when putting products into production.

    Opis:
    In the paper the implementation process of commercial flight and navigational controller in own aircraft is shown. The process of autopilot integration were performed for the fixed-wing type of unmanned aerial vehicle designed in high-wing and pull configuration of the drive. The above equipment were integrated and proper software control algorithms were chosen. The correctness of chosen hardware and software solution were verified in ground tests and experimental flights. The PID controllers for longitude and latitude controller channels were selected. The proper deflections of control surfaces and stabilization of roll, pitch and yaw angles were tested. In the next stage operation of telecommunication link and flight stabilization were verified. In the last part of investigations the preliminary control gains and configuration parameters for roll angle control loop were chosen. This enable better behavior of UAV during turns. Also it affected other modes of flight such as loiter (circle around designated point) and auto mode where the plane executed a pre-programmed mission.

    Opis:
    The investigations of the system which allow to avoid obstacles by the unmanned aerial vehicles (UAV) are presented in the paper. The system is designed to enable the full autonomous UAV flight in an unknown environment. As an information source about obstacles digital camera was used. Developed algorithm uses the existing relations between the imaging system and the parameters read from the UAV autopilot. Synthesis of the proposed obstacle avoidance control law was oriented for computational simplicity. Presented algorithm was checked during simulation studies and in-flight tests.

    Opis:
    Artykuł przedstawia ogólne uwagi związane z tworzeniem systemów sterowania i nawigacji tolerujących uszkodzenia pojawiające się w ich elementach składowych. Główną uwagę zwrócono na uszkodzenia w układach wejścia. Jako przykład omówiono odtwarzanie uszkodzonych sygnałów pomiarowych za pomocą estymat wyznaczanych na drodze analizy modelowania procesów fizycznych zachodzących w rozpatrywanym systemie. Metodę tą zastosowano również do zademonstrowania możliwości wyznaczania zwielokrotnień umożliwiających przeprowadzenie diagnozy systemu.
    The paper presents basic remarks about construction of fault tolerant control and navigation systems for UAV. Reliability and safety requirements can be fulfill with usage of redundancies. Presentation of different kinds of avionic redundancies with comments about their usage during fault appearance is an important part of the paper. The main authors' attention is paid to faults in input devices. Their first goal of UAV measurement devices is generating the information of high quality, but the information must be dependable. On the basis of the authors' work experience, the application of signal estimation with remarks about their precision is introduced. After the general information about the troubleshooting in UAV measurement systems, the usage of a complementary filter for calculations of the roll angle is presented. Moreover, two methods of roll angle estimation are given with comments. The comparison of two methods of navigation parameter calculation as the diagnostic method application is also described. The considered applications have specific feature of UAV avionics systems in the presence of faults.
