The paper reviews the significance of conducting test flights and the statistical analysis of air events in their course. It was demonstrated that it is necessary to support the processes of analysing and evaluating the selection of the crew for tasks conducted using a specific aerial vehicle. The authors presented an IT system supporting superiors supervising test flights, simultaneously increasing the effectiveness of managing safety and preventive actions. The system's design was briefly described and its operation confirmed using selected examples. The results were graphically visualized, in a manner exhibiting high legibility and simplicity of the system's operation.

W artykule przedstawiono znaczenie wykonywania lotów próbnych oraz analizę statystyczną zdarzeń lotniczych podczas ich realizacji. Wykazano, że niezbędne jest wsparcie procesów analizy i oceny doboru załogi do zadań wykonywanych na konkretnym statku powietrznym. Zaprezentowano opracowany system informatyczny wspierający przełożonych podczas prowadzenia nadzoru nad lotami próbnymi, zwiększając jednocześnie skuteczność zarządzania bezpieczeństwem i działaniami profilaktycznymi. W skrócie przybliżono budowę systemu, a jego działanie potwierdzono na wybranych przykładach. Wyniki zobrazowano graficznie, w sposób pokazujący dużą czytelność i prostotę działania systemu.

This article presents the results of research concerning the determination of an error of the vertical position of an aircraft during a flight, taking into account, the flight altitude and the values of the ZTD tropospheric product. In particular, this work focuses on the impact of an error in designating the ZTD tropospheric product on the correct determination of a flight altitude. The authors of this work performed a scientific experiment for research data of two flights made by a Cessna 172 around the aerodrome in Dęblin. This article shows the findings of the tropospheric ZTD product specified for the singlefrequency SPP positioning method and dual-frequency PPP positioning method. Based on the obtained results, it was discovered that the error of the ZTD tropospheric delay causes an altitude error from 0.08 m at the zenith angle equal to 80o even to 0.79 m at the zenith angle equal to 85o.

The X3 helicopter is the experimental demonstrator of the H3 compound helicopter concept (High speed Hybrid Helicopter) developed by Airbus Helicopter and intended to operate at cruise speeds of about 113 m/s (220 kt). It is equipped with short fixed wings and two side-mounted propellers. Usually, fixed-wing propellers are sized to optimize the power consumption in cruise flight. In the case of a compound helicopter, some other flight cases such as hover and descent in autorotation also have to be considered. The geometrical criteria to satisfy all flight regimes may be contradicting what implies a compromise and a new approach to the propeller design. This paper presents the different steps of X3 propellers design from novelty theoretical Blade Element Method studies confirmed by CFD, experimental and flight tests.
