Datalink<\/strong> is defined as CPDLC<\/strong> and ADS-C<\/strong>. If you’re missing either CPDLC or ADS-C, then you’re not datalink equipped. Since 2021, datalink is mandated (DLM) for the entire NAT region between FL290-410<\/strong> [NAT Doc 007, Ch 1.8]. The only exception is flights STS\/FFR, HOSP, HUM, MEDEVAC, SAR, or STATE.<\/p>\n Without datalink<\/strong><\/span>, you can only enter these areas on the North Atlantic FL290-410 [NAT Doc 007, 1.8.2]:<\/p>\n The only complete crossing available is therefore via the Iceland-Greenland<\/strong> corridor. For this, you need ADS-B<\/strong> west of 30W.<\/p>\n So, if you have ADS-B, and the remaining NAT HLA<\/strong> requirements, you can make a crossing at normal altitudes (eg. FL380) through this airspace.<\/p>\n For planning purposes, this area is bounded by the following: If you don’t have ADS-B<\/strong><\/span>, then this crossing is not available between FL290-FL410.<\/p>\n In this case, you should plan to cross the ocean at FL280 or below, or FL430 or above. This in turn places you outside the NAT HLA, as the HLA levels are FL285-FL420. A crossing at FL280 may mean a fuel stop, in Iceland for example (BIKF or BIRK are commonly used).<\/p>\n You can<\/strong> request a climb or descent through Datalink Mandated airspace from ATC, and this is commonly granted, but you do need HLA approval<\/strong>.<\/p>\n <\/p>\n Comment below<\/a><\/strong>.

\nThe Santa Maria Corridor will allow you to fly out to the Azores and back, but won’t help with a full NAT crossing due to the gap between Santa Maria surveillance and the New York oceanic boundary. To use this corridor, you need a Mode S transponder with extended squitter for ADS-B. [NAT Doc 007, 1.8.5 b]\nThis didn’t answer your question?<\/strong><\/h6>\n
