DO-205
Design Guidelines and Recommended Standards to Support Open Systems Interconnection for Aeronautical Mobile Digital Communications
Part 1 — Internetworking
Latest Revision March 21, 1990
Prepared by RTCA SC-162

DO-205 is a software standard published by RTCA, Incorporated. A variety of existing and planned communication systems are needed to support data transfers within the aeronautical domain. To get these diverse systems to interoperate in the most efficient manner, a set of common protocols must be adapted and implemented by all of the participating systems. The resulting network is referred to as the Aeronautical telecommunications network (ATN).

The common set of protocols used to implement ATN have been selected from a larger set of Open sysems interconnection standards which have been developed by the International Organization for Standardization (ISO). The ATN protocols, together with their specific implementation profiles, are being formally documented as Standards and Recommended Practices (SARPS) by the International Civil Aviation Organization (ICAO) for implementation worldwide.

To assist these efforts, RTCA has prepared DO-205 to anticipate and complement the SARPS. It addresses the expected questions of users, the designers, and the implementors of the various elements of the ATN. Examples are provided based on the expected implementation of the ATN elements within the United States.

NOTE: DO-205 is no longer available from the RTCA.
