This guidance standard was prepared in response to a need stated by air transport operators for uniformity in further subdividing the ATA Spec. 100 number system to better accommodate avionics systems. The ATA numbers are widely used in the maintenance community for inventory control, instruction manuals and equipment modification Service Bulletins.

This specification defines the addressing plan and rules for addressing used in Aircraft Data Networks (ADN). The plan is organized in accordance with the seven-layer Open Systems Interconnection (OSI) Reference Model. The specification sets forth the structure of addresses that are employed in the ADN and guidance for address determination. This guidance ensures that all applications - that use this address structure to send messages - can know the address structure of the destination(s) at configuration-time.

With the emergence of RFID (Radio Frequency Identification) as a tool to streamline the supply chain, the airline industry determined that a technology standard for both the RFID tag hardware and data needed to be developed. This is required so that industry-wide interoperability can be achieved. Fundamental requirements have been identified and agreed upon by the airline industry. These core requirements build the framework from which this standard was derived. The usage of an open standard UHF-RFID technology will benefit the entire airline industry. While the intent of this document is to address the usage of UHF-RFID tags on aircraft parts, the technology and benefits are applicable to other items that would be in airline inventory. To that extent, the term Product has been used in this standard. This document is specific to the requirements for and installation of UHF-RFID tags and does not address data usage or the tools and systems used to collect the data.

The On-Board Diagnostics II (OBD-II) port began as a means of extracting diagnostic information and supporting the right to repair. Self-driving vehicles and cellular dongles plugged into the OBD-II port were not anticipated. Researchers have shown that the cellular modem on an OBD-II dongle may be hacked, allowing the attacker to tamper with the vehicle brakes. ADAS, self-driving features and other vehicle functions may be vulnerable as well. The industry must balance the interests of multiple stakeholders including Original Equipment Manufacturers (OEMs) who are required to provide OBD function, repair shops which have a legitimate need to access the OBD functions, dongle providers and drivers. OEMs need the ability to protect drivers and manage liability by limiting how a device or software application may modify the operation of a vehicle.
