Scope of Document

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
• 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
