  1. ACP WG BWork Program • Frequency Planning Criteria • VDL Mode 2 • VDL Mode 3 • VDL Mode 4 • VDL Mode 4 Global Signaling Channel • On-board aircraft compatibility

  2. Papers for WG B18TH Meeting, 17-25 February 2005Bangkok, Thailand • Working Paper 9, Report of VDL Mode 3 Voice Quality Tests With Radio Interference, by Yasuyoshi Nakatani, Japan

  3. VDL Frequency Planning • WGB/17 completed the frequency assignment planning material, including relevant guidance material, for VHF digital link (VDL) Modes 2 • VDL Mode 3 could operate on the fourth adjacent 25 kHz channel from a DSB-AM assignment and on the second adjacent 25 kHz channel from a VDL Mode 3 assignment. • Test planning for VDL Mode 4, including the need for an assignment in the 112-117.975 MHz band is on-going. • Excerpt From ACP-Memo/02, 14/01/05, from ACP Secretary to Members, Aeronautical Communications Panel (ACP)

  4. Summary VDL Mode 2 Frequency Planning Criteria1 Number of Channels for no planning Note: 1. WGB16/WP14 Appendix (after Tokyo) from AMCP/8-WP/66 5J-20 Appendix J to the Report on Agenda Item 5.

  5. Summary VDL Mode 3 Frequency Planning Criteria1Number of Channels for no planning • Notes: 1. WP-WGB17 Document 08, 17th Meeting of Aeronautical Communications Panel Working Group B (ACP WG-B) Montreal, Canada, 20 to 25 October 2004 and 26 to 28 October 2004, VDL Mode 3 to VDL Mode 3 Avionics Interference Testing, Agenda Item 4: VDL frequency assignment planning criteria for VDL Mode 3, Presented by the United States of America. 2. ACP-Memo/02, 14/01/05, Ref SP 62/2, To Members, Aeronautical Communications Panel (ACP), From ACP Secretary, Progress of Aeronautical Communications Panel (ACP) Subject, To note and provide comments by 15 February 2005.

  6. Status Frequency Planning CriteriaVDL Mode 4 • Test Plan Presented to WG B • Testing according to the test plan is planned for early next year. • Reference: ACP (WG B), 17th Meeting, 20 – 25th of October 2004, Montreal, Canada Signalling Channels for VDL Mode 4, F. Lindblom, Swedish CAA, Sweden

  7. VDL Band implementation target planagreed by the EANPG FMG. Reference: ACP (WG B), 17th Meeting, 20 – 25th of October 2004, Montreal, Canada Signalling Channels for VDL Mode 4, F. Lindblom, Swedish CAA, Sweden

  8. Future Work • Further work was needed to complete the the work on Frequency Planning Criteria. • VDL Mode 3 to VDL Mode 2 • VDL Mode 4 to VDL Mode 2 • Guidance material on 8.33 kHz and 50 kHz radios. • There are currently no plans to provide further guidance material on 50 kHz radios, unless required.
