  5. NASData Link Transition • FAA views VDL Mode 2 and VDL Mode 3 as complementary, not competing technologies • CPDLC initially will be fielded on VDL-2 • Only viable technology in required time (2005-2006) • Stepping stone for data link use in air traffic control • FAA pays ATC message charges • CPDLC available on VDL-3 in 2012 • Potential for other applications (e.g. weather) on VDL-3 • Datalink applications still available to VDL-2 service providers • Users would pay any associated message charges • VDL-2 remains essential for the purpose it was developed • AOC and other air traffic management functions • FAA does not plan to provide AOC-type information on VDL-3

  6. International Harmonization FAA strongly supports the 1995 ICAO COM/OPS/DIV decision for digital, TDMA-based voice and data link as the future air/ground communications technology
