The purpose of this North Atlantic Operations Bulletin is to provide background information and guidance material to North Atlantic (NAT) operators that could be included in pilot and dispatcher training programs and operations manuals to best prepare them for FANS 1/A (CPDLC/ADS-C) operations in the NAT to include the use of CPDLC route clearance uplinks.

The NAT OPS SEI (Special Emphasis Items) addresses CPDLC issues and Sections 3 and 4 of this bulletin are particularly important to review and understand.
