What is required to fly over the North Atlantic?

• A. FANS 1/A+
• B. CPDLC only
• C. RVSM
• D. ADS-B Out

Answer: (A)

The key idea is that North Atlantic operations rely on data-link capabilities that support both routing clearances and automatic position reporting. FANS 1/A+ provides the integrated package of CPDLC (text-based controller communication) and ADS-C (automatic position reporting) needed for oceanic clearances and surveillance on the NAT tracks. Having this capability ensures you can receive and send clearances and share position updates reliably while flying the North Atlantic Organized Track System. CPDLC alone wouldn’t meet the oceanic requirement because it lacks the automatic ADS-C reporting that ATC uses to monitor and manage aircraft over the ocean. RVSM deals with vertical separation and isn’t the gating factor for NAT entry, and ADS-B Out is a surveillance requirement in some regions but not the specific NAT data-link standard needed for these routes. So the FANS 1/A+ capability, which encompasses both CPDLC and ADS-C, is what enables flying over the North Atlantic.
