Subcommittees & Working Groups

The AOC Subcommittee develops and maintain a set of standardized AOC messages (ARINC 633) capable of being used by multiple airlines on multiple aircraft types.

The AGCS Subcommittee develops ARINC Standards that ensure that current and emerging satellite air-ground communication system definitions are aligned with airline operational requirements and defined for cost-effective implementation. This includes Inmarsat (ARINC 781) and Iridium (ARINC 771) services.

The goal of the APEX Subcommittee is to develop ARINC 653, Avionics Application Software Standard Interface, defining a standard interface between avionics application software and Real Time Operating System (RTOS).

The CDS Subcommittee develops ARINC 661 flight deck display interface standards for primary flight display and related applications (e.g., FMS) widely used on all aircraft types. Growth for CNS/ATM applications that provide advanced operational concepts, such as touch screen, is provided.

The Data Link Users Forum is a coordinating activity among airlines and cargo carriers, data link service providers, aircraft manufacturers, avionics manufacturers, and others. It focuses on technical issues of mutual interest to operators. The discussions lead to the identification and resolution of numerous issues that collectively improve data link performance. The product of this activity assures that operators receive significant operational and economic benefits of air/ground communication services. 

The EFB Users Forum is a joint activity with IATA that enables airlines and other aircraft operators to state their preferences in the evolution of EFB hardware, software applications, and connectivity to the ground. This ensure operational benefit to the flight deck crew and the economic benefit to the airlines. Flight Operations, Information Technology, Engineering, and Maintenance disciplines are represented among the participants of the EFB Users Forum.

 ARINC 702A Flight Management Computer standards are developed for emerging airspace requirements and take advantage of advancements in Communication, Navigation and Surveillance (CNS), all with the collective goal to increase the capacity and efficiency of the airspace.

The goal of the GAT Working Group is to propose solutions that can positively identify and track an aircraft with minimal impact on aircraft production and retrofit.

The IPS Subcommittee leads the standardization effort to provide ATN/IPS safety services to the aircraft. It will define a transition path from ACARS and ATN/OSI services to ATN/IPS as the end state. ARINC Report 658 provides the roadmap to ATN/IPS. Technical requirements are coordinated with aviation Standards Development Organizations (SDOs), Air Navigation Service Providers (ANSPs) and others.

The NDB Subcommittee maintains ARINC 424 data base standards used with Flight Management Computers and Flight Management Functions to improve overall aircraft performance.

The SDL Subcommittee develops ARINC Standards for software data loading. This includes standards for file format, media type, part numbering and terminology will be developed in a way that can be used for various data loading devices.

The goal is to maintain Traffic Surveillance standards which define avionics airborne equipment with Traffic Alert and Collision Avoidance System (TCAS), Air Traffic Control Transponder (ATCRBS/Mode S), and Automatic Dependent Surveillance-Broadcast (ADS-B) functionalities.

The Field Loadable Software (FLS) Working Group will update ARINC 667 to maintain common terminology, management practices, communications standards, storage formats, and distribution methods related to aircraft software configuration management.

The SATCE Working Group will update ARINC Report 439: Guidance for Simulated Air Traffic Control Environments in Flight Simulation Training Devices. The project will result in Supplement 1 to ARINC Report 439.
