Advisory Circular (AC) 91-70, "Oceanic and Remote Airspace Operations" contains general information and guidance for operators planning flights in oceanic and remote airspace, including authorizations needed for operations outside the continental United States. This includes Performance-based Navigation (PBN) and Special Areas of Operation (SAO). 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. Additionally, the FAA identifies critical areas and procedures such as Strategic Lateral Offset Procedures (SLOP). The dynamics of oceanic and international operations are such that procedures change and therefore it is incumbent upon operators planning such flights to regularly review the appropriate guidance material to identify where changes have occurred.
