of ACARS VDL cloud seems not continuous between Narita and

Kansai.

Need more VGSs to cover whole airspace over Japan.

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.
