APPENDICES TO ANNEX III

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.
