EUROCAE ED-77A PDF

This document provides the minimum requirements and reference material applicable to the content, origination, publication, and updating of navigation data and related operational data. The objective of this document is to support the creation of the data quality requirements for navigation databases by end users and application integrators in accordance with DO-200B/ED-76A provisions. Navigation data originators and providers can benefit from using this document when developing data for their users. It is also intended to provide procedure designers and developers of procedure design criteria a basic understanding of the coded navigation data.

Navigation data is information needed for the position and path definition of an aircraft. This includes, but is not limited to: waypoints, airports and runways, routes and procedures, navaids, and landing system infrastructure. It excludes terrain, obstacle, and cultural data (e.g., geopolitical borders, water features, etc.).

Operational data is data that is not required for navigation, but used for navigation operations. It includes, but is not limited to, airspace, communication, and aerodrome data.

The data requirements included in this standard have been compiled in order to support the functions and applications listed in Appendix A; however, this document does not define requirements for the applications themselves.
