Avsoft introduced a North Atlantic High Level Airspace (NAT HLA) general subject course that explores the important concepts, definitions, equipment, procedures and requirements related to operations in the NAT HLA.

This course is based on the International Civil Aviation Organization (ICAO) North Atlantic Operations and Airspace Manual (NAT Doc 007), V.2018-1, and includes four modules:

  • Introduction covers NAT HLA structure, aircraft separation, including RLatSM, RLongSM, and RVSM, required equipment, including RNP, PBCS, and LRNS, and NAT CMA monitoring of operations.
  • Route Structures covers the Organized Track System (OTS), random tracks, Blue Spruce routes, special routes, and polar tracks.
  • Normal Procedures covers required documents, FMS flight plan entry, plotting charts, oceanic clearance and entry, Strategic Lateral Offset Procedure (SLOP), oceanic exit, and post flight.
  • Contingency Procedures covers equipment failures, external factors, emergency situations, and volcanic ash.
The course is designed to comply with European Aviation Safety Agency (EASA), Federal Aviation Administration (FAA), ICAO and Transport Canada regulations and to provide pilots with about five hours of initial training. Customers have the option of customizing the course to be suitable for recurrent training, each module concludes with a test and a certificate of completion is generated when all the modules are successfully completed.
