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.
EASA aviation regulations define an aeronautical data catalogue organizing aerodrome, airspace, routes, procedures, navigation, obstacle, and geographical data. This catalogue specifies data subjects, properties, types, descriptions, accuracy, integrity, origination, and resolution for aeronautical information management, ensuring aviation safety and data quality.
