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.
