ARINC Specification 858P1:2021

ARINC 858 Part 1 defines the airborne data communication network infrastructure for aviation safety services using the Internet Protocol Suite (IPS). ARINC 858 builds upon ICAO Doc 9896, Manual on the Aeronautical Telecommunication Network (ATN) using Internet Protocol Suite (IPS) Standards and Protocol. IPS will extend the useful life of data comm services presently used by operators, e.g., VDL, Inmarsat SBB, Iridium NEXT, and others. It represents the evolutionary path from ACARS and ATN/OSI to the end state: ATN/IPS. ARINC 858 includes advanced capabilities such as aviation security and mobility. This product was developed in coordination with ICAO WG-I, RTCA SC-223, and EUROCAE WG-108.
