10/4/16 AC 91-70B
1-1
CHAPTER 1. GENERAL
1.1 Purpose. The Federal Aviation Administration (FAA) (“we”) developed this advisory
circular (AC) to provide general information and guidance for commercial and General
Aviation (GA) operators (“you”) planning flights in oceanic and remote continental
airspace. This guidance includes the authorizations you need for operations in such
airspace outside the continental United States (CONUS).
1.2 Cancellation. AC 91-70A, Oceanic and International Operations, dated August 12, 2010,
is canceled. AC 91-70, Oceanic Operations, and the North Atlantic International General
Aviation Operations Manual (also known as the NAT IGA) are also obsolete.
1.3 Applicability. We have primarily targeted this AC at operators who do not yet have set
procedures for flights through this type of airspace and can use this AC as a guide
in developing their own procedures. We are also targeting GA pilots who do not fly
regularly in oceanic and remote continental airspace and need a refresher on what
to consider before, during, and after such a flight. Most commercial operators have
company procedures for operations in oceanic and remote continental airspace. Those
procedures have been accepted by FAA inspectors and conform to all relevant regulations
and guidance. If you are working for one of these operators, this AC may serve
to reinforce your company procedures.
1.4 Fundamental Changes from Previous Edition. Procedures for operating in oceanic and
remote continental airspace are constantly evolving, and you should closely monitor any
changes. We revised this AC to point you to the most current sources of international
material. In some cases, we refer you to a Web site. You can also find supplements to this
material by starting at www.faa.gov or by calling an FAA Special Areas of Operation
(SAO) specialist. Contact information for your regional SAO specialist can be obtained
from your local Flight Standards District Office (FSDO) or certificate management office
(CMO). You may also be able to find this contact information on the North Atlantic
(NAT), Pacific (PAC), and West Atlantic Route System (WATRS) Resource Guides.
In this AC, we include specific guidance for authorizations and conformance with other
FAA policy issues. Host nation Aeronautical Information Publications (AIP) and
international Notices to Airmen (NOTAM) also contain the most recent information.
