New, single CPDLC logon for US airspace

In case you missed the several hundred Notams this week, KUSA is the new identifier for all datalink logons in the US, including CPDLC-DCL, and enroute, which came into use on October 22nd. Now, the only logon you need is KUSA.

For all you could possibly want to know about Datalink operations in the US, take a peek at the new AC90-117, ” an overview of data link communication operations for U.S. domestic
operations and in oceanic and remote continental airspace”, which we’ve uploaded here.

More readable is the FAA’s CPDLC-DCL guide, uploaded here.

There are some comments that it doesn’t work properly if you don’t have an active FPL in the box, let us know your experiences on that in the comment section below.
