This document provides airlines, airframe manufacturers, aircraft equipment suppliers, and others with information that is specific to data, software, and ground tools used in aviation configuration and data management. As a starting point, this document provides guidance on: Which standard to use in specific situations The use of and how integrity checks should be applied Common terminology in airborne software management Since airplanes started using software controlled hardware, there has been a need to standardize processes and terminology. This document is the centroid to which other software standards are related.

The difficulty in locating crash sites has prompted international efforts for alternatives to quickly recover flight data. This document describes the technical requirements and architectural options for the Timely Recovery of Flight Data (TRFD) in commercial aircraft. ICAO and individual Civil Aviation Authorities (CAAs) levy these requirements. The ICAO Standards and Recommended Practices (SARPs) and CAA regulations cover both aircraft-level and on-ground systems. This report also documents additional system-level requirements derived from the evaluation of ICAO, CAA, and relevant industry documents and potential TRFD system architectures. It describes two TRFD architectures in the context of a common architectural framework and identifies requirements. This report also discusses implementation recommendations from an airplane-level perspective.

The purpose of this document is to evaluate Communication, Navigation, and Surveillance (CNS) Distributed Radio architectures and the feasibility of distributing the RF and systems processing sections to ensure the following: Reduce cost of equipment Reduce Size, Weight, and Power (SWaP) Ease of aircraft integration Growth capability built into the design Maintain or improve system availability, reliability, and maintainability It provides a framework to determine whether it is feasible to develop ARINC Standards that support CNS distributed radio architectures.

The purpose of this document is to provide guidelines for integrating previously standalone cabin systems such as cabin management systems, In-Flight Entertainment (IFE) systems, In-Flight Connectivity (IFC) systems, galley systems, surveillance systems, etc. Resource sharing between systems can reduce airline costs and/or increase functionality. But, as systems expose their internal resources to external systems, the risk of an intrusion that could degrade function and/or negatively expose the supplier’s or airline’s brand increases. This document provides a recommended IP networking design framework between aircraft systems to reduce the operational security threats while still supporting the necessary intersystem routing.

ARINC 858 Part 2 provides aviation ground system gateway considerations necessary to transition to the Internet Protocol Suite (IPS). ARINC 858 Part 2 describes the principles of operation for an IPS gateway that enables ACARS application messages to be exchanged between an IPS aircraft and a ground ACARS host. ARINC 858 Part 2 also describes the principles of operation for an IPS gateway that enables OSI-based application messages to be exchanged between an IPS host and an OSI end system. This product was developed in coordination with ICAO WG-I, RTCA SC-223, and EUROCAE WG-108.

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.

This document defines a standard implementation for strong client authentication and encryption of Wi-Fi-based client connections to onboard Wireless LAN (WLAN) networks. WLAN networks may consist of multi-purpose inflight entertainment system networks operating in the Passenger Information and Entertainment System (PIES) domain, dedicated aircraft cabin wireless networks or localized Aircraft Integrated Data (AID) devices operating in the Aircraft Information Services (AIS) domain. The purpose of this document is to focus on the client devices requiring connections to these networks such as electronic flight bags, flight attendant mobile devices, onboard Internet of Things (IoT) devices, AID devices (acting as clients) and mobile maintenance devices. Passenger devices are not within the focus of this document.

The purpose of this standard is to provide a method for packaging aircraft software parts for distribution using contemporary media or by electronic distribution. This project intends to standardize and provide guidance for the storage of floppy based software, currently packaged in media set parts. This standard format can be then stored or distributed on a single physical media member (CD-ROM), or by electronic crate. The obsolescence of floppy disks drive an urgent need for this guidance.

This document defines the User Interface Markup Language (UIML) which allows developers to specify the interface, look, and behavior of any Graphical User Interface (GUI). The GUI consists of several components, from the simplest, called primitive components (such as rectangle, text, image, group), to more complex components built by the aggregation of several primitive components and by providing relational specific logic. Also defined is the execution model, which provides the rules to interpret the language so that the graphical user interface has a standardized and consistent behavior defined for any platform.

ARINC Specification 620 defines the interfaces between the Datalink Service Provider (DSP) and the aircraft, other ground-based datalink services, and users. The datalink ground system standard definition supports traditional ACARS and AOA protocols, as well as Media Independent Aircraft Messaging (MIAM) as defined by ARINC Specification 841. MIAM messages can be much larger than ACARS messages (5 MB versus 3.3 kB per message). Supplement 10 improves Controller-Pilot Data Link Communications (CPDLC) by defining a “Deliver By (DB)” period that allows the DSP, that originated the message, to intercept and discard the message if it is not delivered by the specified time. Supplement 10 also adds a Media Advisory code for ACARS over IP (AoIP) indicating that an ACARS non Safety Services messages is being transferred over IP links. New Reason Codes are assigned for un-transmittable or undeliverable messages. ACARS Character set clarifications are also provided in Supplement 10.
