Aircraft Generation ARINC Standards:

The Airlines Electronic Engineering Committee (AEEC) develops the ARINC Standards, including contributions from aviation vendors such as Collins Aerospace and GE Aviation in support of its airline customers. The condensed version of the list can be found on Wikipedia/arinc_standards.

• ARINC Characteristics: Define the form, fit, function, and interfaces of avionics, cabin systems, and aircraft networks.
• ARINC Specifications: Define the physical packaging or mounting of avionics and cabin equipment, communication, networking, and data security standards, or a high-level computer language.
• ARINC Reports: Provide guidelines or general information found by the aviation industry to be preferred practices, often about avionics maintenance and flight simulator engineering and maintenance.

ARINC Standards

ARINC Standards specify the air transport avionics equipment and systems used by more than 10,000 commercial aircraft worldwide. AEEC, AMC, and FSEMC, the aviation industry activities organized by ARINC, cooperatively establish consensus-based, voluntary aviation technical standards that no one organization could develop independently. Technical standards adopted by the AEEC, AMC, and FSEMC are published as ARINC Standards by the ARINC Industry Activities secretariat. 

ARINC Standards describe avionics, cabin systems, protocols, and interfaces used by more than 10,000 air transport and business aircraft worldwide. Learn more about ARINC Standards.

• 400 Series – 400 Series ARINC Specifications and Reports provide a design foundation for equipment specified per the ARINC 500 and 700 Series. They include guidelines for installation, wiring, data buses, databases, and general guidance.
