91-70A AFS-400 Oceanic and International Operations

 

This advisory circular (AC) contains general information and guidance for operators planning oceanic flights, including authorizations needed for operations outside the continental United States. This includes Special Areas of Operation (SAO) such as North Atlantic Minimum Navigation Performance Specifications (NAT/MNPS), Reduced Vertical Separation Minimum (RVSM), Area Navigation (RNAV), and Required Navigation Performance (RNP) airspace.

a. Initiatives.

 

In all geographic regions, the evolution of communication, navigation, surveillance and air traffic management (CNS/ATM) is the catalyst for initiatives such as data link, RNP, RNAV, Automatic Dependent Surveillance (ADS), and RVSM.

b. Critical Areas and Procedures.

The Federal Aviation Administration (FAA) identifies critical areas and procedures such as Strategic Lateral Offset Procedures (SLOP).

c. Revisions.

The dynamics of oceanic operations are such that they are constantly evolving and it is incumbent on the operators to closely monitor any changes. The FAA revised this AC to point the reader to the most current sources of international material. In many cases, the references are to a Web site. The material, however, is still found at www.faa.gov or by calling an FAA navigation specialist. This AC includes specific guidance for authorizations and other FAA policy issues. A detailed study of the FAA Web site is the best source for introduction information about oceanic, international, and remote operations.
