NEXCOM Next Generation Air/Ground Communications                                NEXCOM Next Generation Air/Ground Communications AEEC General Session December 2001 Jim Eck Air/Ground Communications Product Team Lead

NEXCOM Program Background NARC Recommendations & FAA Response Report on spectrum status FAA to provide annual update of status & projected demand Continue to support VDL-2 development FAA uses VDL-2 as incubator of datalink program and operational concept validation FAA expects combined capacity of VDL-2 & VDL-3 required to meet RTCA Combined Operational Concept & OEP objectives Expedite system demo of VDL-3 in a certified system FAA will demo a “certifiable” VDL-3 voice system and an “interoperable” data system by 2004 in advance of rule publication

NEXCOM Program Background NARC Recommendations & FAA Response Develop an alternative plan if VDL-3 proves untimely FAA begins deployment of 8.33 capable radios in 2003 Lead development of common next generation communications system FAA believes VDL-3 is next system through 2030 FAA will work with ICAO to jointly study VHF architecture & critically review alternate band solutions as proposed

NEXCOM Program Risks Issue: Certified Avionics availability Action Plan: FAA/Airspace Users to collaborate on demo schedule & participation FAA/Industry to develop partnership agreements to develop, install & test avionics FAA/Users to provide in-kind support to demo operations Status: System Architecture & Integration Committee work – complete Characteristics development – pending AEEC General Session

NEXCOM Program Recommended Action: Approve initiation of VDL-3 characteristics development based upon existing 750 architecture
