Difficulties - VDLDifficulties - 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/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.
