CPDLC
Whenever I operate out of LHR and am transsitting Maastricht and then into Rhine (and the reverse route of course) I log on to EDYY and receive a CPDLC service. On leaving Mastricht into Rhine my little DCDU informs me that EDUU is the next unit, and flying into UK that EGTT is the next active unit. No CPDLC serevice is received and I am just curious as to when and if these units will ever be providing a CPDLC service??
