NORTH ATLANTIC OPERATIONS
HIGH LEVEL AIRSPACE (NAT HLA)
The airspace formerly known as the “North Atlantic Minimum Navigational Performance Specifications Airspace”, in other words NAT MNPS area, was re-named to North Atlantic High Level Airspace, or in short: NAT HLA. The airspace of the North Atlantic, which links Europe and North America, is the busiest oceanic airspace in the world. Our HLA course explains the basic rules and guidelines on how to perform a safe operation across the NAT HLA area.
The course is designed to be completed in average of 1 hour and 10 minutes.
