1 S. Matsuzaki Director Engineering S. Matsuzaki Director Engineering & & VDL Mode 2/AOA Initial Operating Conditions Experience VDL Mode 2/AOA Initial Operating Conditions Experience AVICOM Japan

2 AVICOM Japan ACARS Service deployed APR AOC Interoperability was established between SITA (1990) and ARINC (1991) Connected to KDD Yamaguchi GES for SATCOM Data service (1990) Head Office. Minato-ku, Tokyo Capital. 1,310 Million Yen Stockholders JAL, ANA, JAS, NTT, KDDI, NTT data etc ACARS Service deployed APR AOC Interoperability was established between SITA (1990) and ARINC (1991) Connected to KDD Yamaguchi GES for SATCOM Data service (1990) Head Office.

3 ACARS Current Status as of Oct ACARS RGS in operation now. Base Frequency = MHz 2 nd Frequency = MHz at 7 Major airport Approx. 2.2 Million Blocks / month Up link success rate : Approx. 92 % 49 ACARS RGS in operation now.

4 ACARS Traffic trend Blocks

5 Success rate history Uplink success

6 Driving factor toward VDL AOA Steady growth of data link traffic Need faster & reliable means to avoid capacity constraint. Steady growth of data link traffic Need faster & reliable means to avoid capacity constraint. ATN (VDL M2) as 2nd step for ATS VDL AOA (ACARS Over AVLC) 1 st step for AOC delivery improvement VDL AOA (ACARS Over AVLC) 1 st step for AOC delivery improvement

7 VDL/AOA implementation Contract with Mar IOC : September 2003 at Narita & Kansai A/P. 10 airports were selected as VDL/AOA site at initial phase. Contract with Mar IOC : September 2003 at Narita & Kansai A/P. 10 airports were selected as VDL/AOA site at initial phase.

11 Performance - VDL Initial two weeks experience after IOC. Two aircraft, B ER have logged on to VGS. The airplane has flown Kansai – China (Beijing, Shanghai) Kansai – Haneda Up link success = 98 Gateway per message block Initial two weeks experience after IOC. Two aircraft, B ER have logged on to VGS. The airplane has flown Kansai – China (Beijing, Shanghai) Kansai – Haneda Up link success = 98 Gateway per message block

12 Difficulties - VDL VDL range seems slightly smaller than that of ACARS VDL cloud seems not continuous between Narita and Kansai. Need more VGSs to cover whole airspace over Japan. Blind area at Kansai airport Installation of one more VGS at the other side of the terminal VDL range seems slightly smaller than that of ACARS VDL cloud seems not continuous between Narita and Kansai.

14 Emerging ATN VDL/AOA Sys can be upgraded to an ATN compliant system by adding; Software to handle ATN message Routers for distribution of ATN message And some others. (Hard & Soft) Time for the upgrade depend on the progress of ATN implementation in Japan and World wide.
