Appendix 1 AERONAUTICAL DATA CATALOGUE Regulation (EU) 2020/469 Introduction (a)       The aeronautical data catalogue is a reference to the aeronautical data subjects, properties and subproperties organised in: (1) aerodrome data; (2)       airspace data; (3)       ATS and other routes data; (4)       instrument flight procedure data; (5)       radio navigation aids/systems data; (6)       obstacle data; (7)       geographical position data. (b)       The tables of the aeronautical data catalogue are composed of the following columns: (1)       subject for which data can be collected; (2)       property: an identifiable characteristic of a subject which may be further defined into sub-properties; (3)       same as 2; (4)       types: the data is classified into different types; (5)       description: a description of the data item; (6)       notes: containing additional information or conditions for the provision of the data; (7)       accuracy: requirements for aeronautical data are based on a 95 % confidence level; (8)       integrity classification; (9)       origination type: data is identified as surveyed, calculated or declared; (10)     publication resolution; (11)     chart resolution. Note for items 2 and 3 under point (b): the classification of a catalogue element as subject, property or sub-property does not impose a certain data model. Note for item 7 under point (b): for those fixes and points that serve a dual purpose, e.g. holding point and missed approach point, the higher accuracy applies. Accuracy requirements for obstacle and terrain data are based on a 90 % confidence level. Note for item 10 under point (b): the publication resolutions for geographical position data (latitude and longitude) are applicable to coordinates formatted in degrees, minutes, seconds. When a different format is used (such as degrees with decimals for digital data sets) or when the location is significantly further to the north/south, the publication resolution needs to be commensurate with the accuracy requirements.
