In the context of aviation and aerospace, the "Automated Data Interchange System Service B" refers to a specific type of data exchange system used for the electronic exchange of technical and logistical data between manufacturers, suppliers, and operators.

More specifically, "Service B" is a standardized service provided by the Automated Data Interchange System (ADIS), a global platform used by the aerospace and defense industries to facilitate the exchange of technical data, parts catalogs, and other logistical information.

The ADIS Service B is used for the exchange of technical data such as CAD drawings, technical specifications, and other design-related information. It provides a secure, standardized, and auditable way for companies to share sensitive technical data with their partners, suppliers, and customers.

The use of ADIS Service B enables companies to improve collaboration, reduce errors, and streamline their data exchange processes, ultimately supporting the design, manufacturing, and operation of complex aerospace and defense systems.
