New Comms, Surveillance Requirements Coming for NAT Ops
Compliance with new performance-based communication and surveillance requirements will be required to fly on three North Atlantic Track routes.

Operators flying the North Atlantic Track (NAT) system between FL350 and FL390 must soon comply with ICAO’s new performance-based communication and surveillance (PBCS) requirements. As of March 29, PBCS compliance will be required to fly on three NAT tracks; more tracks requiring PBCS will be added after March 29, 2019, or when the filing of PBCS designators reaches the 90 percent mark.
