The Concept of a Method Ensuring Aeronautical Data Quality

Abstract

The paper presents the concept of a method ensuring quality of aeronautical data. European Union (among others UE 73/2010) as well as international (among others ICAO Annex 15) regulations introduce a number of requirements regarding the quality and safety of aeronautical data. Those directives set up a complementary regulations system. However with their objective and scope they determine mainly the specifications and requirements that are to be implemented and compatible. Mentioned regulations also refer to selected international standards (e.g. ISO 19157), focused on quality and safety of geographic data and information. Nevertheless within the scope of considered regulations and norms no algorithms and methods of ensuring required quality in the process of aeronautical data collection and processing were determined. Taking into account the identified needs, authors proposed the application of statistical method for process quality management – six-sigma.

The concept of DMAIC methodology application for diagnostics of potential incompatibilities in aeronautical data request process

“…Till now a similar analysis for the aeronautical data origination stage was conducted [8]. The scheme, used in practice, was analysed in details and modified by introducing into each step the verification and validation procedures, so that a potential or real incompatibility is diagnosed and identified up to date, and planning and implementation of preventive and correction actions occupies less time.…”

“…In [6] a potential data incompatibility, based on a specific case study, was described and in [15] air transport telematics systems were analysed. [19] contains the concept of potential incompatibilities' diagnostics in the entire aeronautical data and information chain, while its second stage -aeronautical data origination was analysed in [8]. This time, however, attention is paid to the data request process -the first stage of the aeronautical data and information chain, and the application of DMAIC (Define-Measure-Analyse-Improve-Control) methodology for the diagnostics of potential data discrepancies is proposed.…”

The Concept of a Method Improving the Process of Aeronautical Geospatial Data Creation

“…Transport lotniczy jest dyscypliną bardzo silnie obwarowaną regulacjami prawnymi. Przegląd tych wymagań Autorzy przedstawili w kilku swoich poprzednich publikacjach [3,5]. Za najważniejsze wymagania prawne w analizowanym przez Autorów zagadnieniu zapewnienia jakości danych i informacji lotniczych należy uznać Załączniki do Konwencji Chicagowskiej (1944) gdzie: x n -wartość nominalna, k -numer próbki, numer kolejnej mierzonej przeszkody, x m1k -wartość pierwszego pomiaru, x m2k -wartość drugiego pomiaru, b 1k -błąd bezwzględny pierwszego pomiaru, b 2k -błąd bezwzględny drugiego pomiaru, -średni błąd z pomiaru pierwszego i drugiego, R k -rozstęp, oraz towarzyszące im wyniki obliczeń: linia centralna:…”

“…The presented examples confirm the possibility of the considered Shewhart control chart's practical implementation, with the important remark that the control charts method, as a method described in the international standard [8], can be accepted for practical application directly or after an adequate modification. Its implementation at each stage of the aeronautical data and information chain [3,4,5] will enable adoption of resultful and effective preventive as well as corrective actions. This sets out a specific context in the Authors' work which concentrates on looking for adequate practical methods for aeronautical data and information creation processes' statistical quality management.…”

“…"dane i informacje lotnicze"; − zakresu przedmiotowego danych i informacji nautycznych i lotniczych (np. : dane geoprzestrzenne, informacje operacyjne, informacje meteorologiczne) [2,11]; − procedur gromadzenia, tworzenia, publikowania i wykorzystania danych i informacji nautycznych i lotniczych [3,11,18,22];…”
