Controlled and Harmonised Aeronautical Information Network
Encyclopedia
The Controlled and Harmonised Aeronautical Information Network (abbreviated: CHAIN) is a concept developed by EUROCONTROL to improve the quality, integrity, accurary and interoperability
of aeronautical data in kind of a digital data chain avoiding changes in medium in the whole data process.
Using CHAIN regulators of aeronautical informations as well as service providers (ANSPs) can be supported implementing and maintaining traceable, controlled and auditable processes in compliance with ICAO Annex 15 requirements for data quality with a focus on data integrity.
The scope of CHAIN covers flight critical and essential navigational aeronautical data (e.g. a runway threshold coordinates and heights) as established in ICAO Annex 15, supplemented by the industry standards EUROCAE ED-76 and ED-77.
Interoperability
Interoperability is a property referring to the ability of diverse systems and organizations to work together . The term is often used in a technical systems engineering sense, or alternatively in a broad sense, taking into account social, political, and organizational factors that impact system to...
