RTCA DO-349

Description / Abstract: This standard document contains an initial set of industry supported delivery method recommendations for those applications and uses described in RTCA document DO-340, Concept of Use (ConUse) for Aeronautical Information Services (AIS) and Meteorological (MET) Data Link Services. A further service defined in RTCA DO-339, Aircraft Derived Meteorological Data via Data Link for Wake Vortex, Air Traffic Management and Weather Applications Operational Services and Environmental Definition (OSED) is included in the recommendations. These recommendations cover architectural, information sourcing, security, and allocation processes. This document supports the data communications needs of future Air Traffic Management (ATM) concepts (e.g., Next Generation Air Transportation System (NextGen) and potentially provides input for future efforts by the Single European Sky Air Traffic Management Research (SESAR) initiatives). A key objective of these future ATM concepts is to establish the aircraft as a primary participant in collaborative decision making (CDM), and in some cases, establish airspace regions for autonomous operations where the aircraft is primarily responsible for safe separation from other traffic, wake turbulence, weather, and designated/restricted airspace. Timely availability of high quality and reliable electronic AIS and MET information services are necessary to support these global ATM concepts.
