WG-92 is working to maintain the current ED-92B version up to date and synchronized with other VDL standards. ED-92 is used in the baseline for the certification of the avionics systems and has to be consistent with the expectations of the European DLS-IR mandate. In addition, while working on ED-92B which currently only contains test cases for the avionics systems, WG-92 identified the need to add test cases related to ground systems requirements in order to ensure the interoperability of the VDL Mode 2 systems. The group has to determine what these test cases are and determine how these new test cases could be integrated in the existing MOPS. Finally, a VDL Connection-less mode is under study by the VDL working groups as it should improve the system performances and reliability. The on-going discussions may lead to VDL standards update (ICAO 9776, ARINC 631, MASPS & MOPS) and, in that frame, ED-92B should be impacted. In order to reach this objective, WG-92 is working jointly with the AEEC Data Link (DLK) Systems Subcommittee and the RTCA SC-214 VDL Sub-Group. Each group is in charge of a set of VDL-related documents, which are interlinked but cover different aspects.
