Cross the North Atlantic between FL285 and FL420. We build your NAT HLA package, coordinate with your FSDO, and see it through to your B039.
NAT HLA stands for North Atlantic High Level Airspace. It covers most of the North Atlantic oceanic airspace from FL285 to FL420, including the organized track system that carries traffic between North America and Europe.
Aircraft are separated by tight lateral and time standards with no radar coverage, so both the aircraft and the crew must meet set navigation and procedure standards. NAT HLA replaced the older MNPS airspace name in 2016.
If you plan to fly in the NAT HLA, yes. Most crossings also need a few related approvals.
Required for any flight in NAT HLA airspace, FL285 to FL420.
Flying your first crossing? Our International Ops Package handles all of these together.
Two independent long-range navigation systems meeting RNP 10 or RNP 4, as authorized.
Route loading and verification, plotting, position checks, SLOP, and contingency procedures.
Crew knowledge of NAT HLA rules, track messages, communications, and contingencies.
HF or approved SATVOICE, data link where mandated, and the required transponder.
We see these delays over and over. We check for every one of them before anything goes to the FSDO.
Planning FL290–FL410 without CPDLC and ADS-C runs into the NAT Data Link Mandate.
Inspectors want plotting, the 10-minute position check, and contingency procedures in writing.
Equipment codes must match what the aircraft has and what the LOA allows.
LOAs belong to the operator. A sale means a new application.
Each pilot needs documented oceanic and NAT HLA training.
FSDO review time varies. Start well before your first crossing.
Yes, it is the same airspace under a newer name. NAT HLA replaced MNPS in 2016, and the navigation standard is now performance-based (RNP 10 or RNP 4).
For most crossings, yes. RVSM covers FL290 to FL410, and the NAT Data Link Mandate requires CPDLC and ADS-C in that same band.
NAT HLA starts at FL285, so B039 is not required below it. Oceanic rules for navigation, communications, and survival equipment still apply.
Yes. We prepare the amendment and update your manual to match.
