scope:

This document defines an open encoding format for airport databases which are loaded in airborne systems. This format, when designed and implemented, will enable a quick, economic, and efficient use of AMDB. However, since industry does not require applications to be standardized, data interpretation is not addressed in this document.

ARINC Specification 816 includes the following:

•Metadata specifications

•Performance requirements

•Minimum features and attributes derived from DO-272/ED-99

•Coding derived from DO-291/ED-119

•Aggregating features from DO-272/ED-99 capture rules

•Triangulation of geometric features

•Physical file format specification

•Identification number

•Features and attributes including coordinates

•Feature symbolic representation (e.g., anchor positioning)

•Coordinate projection algorithm specification

•Cyclic redundancy check (CRC) algorithm specification

•Binary encoding
