Airborne measurement system during validation of EGNOS/GNSS essential parameters in landing

Abstract The air transport requires certificate of ground and deck devices, systems and adequate procedures. However applied geodetic techniques and measuring technologies depend on taken undertakings. If one should precisely put standard ground systems and the navigational assistance are overbalancing static geodetic techniques and measuring technologies. However operational activity, depending on the phase of the flight a real requires applying geodetic techniques and measuring Jechnologies time”. As part of conducted air tests they made the validation of four fundamental parameters (accuracy, credibility, availability, continuity) of satellite EGNOS, GNSS signals, made as part of European projects: “Support to the EGNOS APV Operational Implementation - APV MIELEC”, air tests enabled to draw right procedures up and to apply satellite signals in the air transport. Details will be presented in the following article.

Implementation of satellite techniques in the air transport

Abstract The article shows process of the implementation satellite systems in Polish aviation which contributed to accomplishment Performance-Based Navigation (PBN) concept. Since 1991 authors have introduced Satellite Navigation Equipment in Polish Air Forces. The studies and researches provide to the Polish Air Force alternative approaches, modernize their navigation and landing systems and achieve compatibility with systems of the North Atlantic Treaty Organization (NATO) and International Civil Aviation Organization (ICAO). Acquired experience, conducted military tests and obtained results enabled to take up work scientifically - research in the environment of the civil aviation. Therefore in 2008 there has been launched cooperation with Polish Air Navigation Services Agency (PANSA). Thanks to cooperation, there have been compiled and fulfilled three fundamental international projects: EGNOS APV MIELEC (EGNOS Introduction in European Eastern Region - APV Mielec), HEDGE (Helicopters Deploy GNSS in Europe), SHERPA (Support ad-Hoc to Eastern Region Pre-operational in GNSS). The successful completion of these projects enabled implementation 21 procedures of the RNAV GNSS final approach at Polish airports, contributing to the implementation of PBN in Poland as well as ICAO resolution A37-11. Results of conducted research which served for the implementation of satellite techniques in the air transport constitute the meaning of this material.

Safety Case as a Necessary Aspect of the Aviation Implementation of the Gnss / Safety Case Jako Niezbędny Aspekt Lotniczej Implementacji Systemu Gnss

Abstract The article describes analysis of the risk for the implementation of precise approach procedures (Localizer Performance and Vertical Guidance - LPV) with GNSS sensor at airports in Warsaw and Katowice. There were used some techniques of the identification of threats (including controlled flight into terrain, landing accident, mid-air collision, missed approach, safe landing) and evaluations methods based on: Event Tree Analysis, probability of the risk, safety risk evaluation matrix and Functional Hazard Assesment. Also safety goals were determined. Research led to determine probabilities of appearing of threats, as well as allow compare them with regard to the ILS. As a result of conducting the Preliminary System Safety Assessment (PSSA), there were defined requirements essential to reach the required level of the safety. Research led to determine probabilities of appearing of threats and safety goals, as well as compare them with regard to the ILS requirements Streszczenie Artykuł przedstawia analizę ryzyka na potrzeby wdrożenia procedur podejścia precyzyjnego (Localizer Performance and Vertical Guidance - LPV) z użyciem sensora GNSS dla lotnisk w Warszawie i Katowicach. Szczegóły zostały zawarte w opracowywanym w ramach międzynarodowego projektu SHERPA. Do analizy wykorzystano techniki identyfikacji zagrożeń (zderzenie z powierzchnią ziemi w locie sterowanym - CFIT, wypadek podczas lądowania - LA, kolizja w powietrzu - MAC, procedura po nieudanym podejściu - MA, bezpieczne lądowanie) i oceny ich następstw oparte o metody analiz: Event Tree Analysis, zestawienie prawdopodobieństwa ryzyka bezpieczeństwa, macierz oceny ryzyka bezpieczeństwa oraz Functional Hazard Assesment. Następnie określono cele bezpieczeństwa. Przeprowadzone badania pozwoliły na wyznaczenie prawdopodobieństw występowania zagrożeń i celów bezpieczeństwa, a także porównanie ich względem wymagań systemu ILS

LPV Flight Trials in Poland

The general idea of this project is to popularize the usage of EGNOS (European Geostationary Navigation Overlay Scientific). Research centers should prepare technical solutions for system installations on airports and on boards of aircraft, in frames certificate of projects and procedures. Under this notion one should understand two types of the certification: technical and operation procedures in flight (procedures of tricking both landing for aircraft and airports). Peculiarly they are being taken into consideration: safety while carrying out flights and Safety Case (analyses of the safety). Appropriately the prepared specialist, based on the specially prepared technical documentation, is making the essential installation equipping the EGNOS system, both on the board of the aircraft and on the airport, and next performs certification flights. To underline he belongs, that this appropriately prepared specialist should also supervise and conduct the practical training for the aircraft crew and ground, of which acquainting with functioning the EGNOS system and his implementation are a purpose while making of flights both procedures of the approach and landing.
