Use of Portable Electronic Devices Aboard Aircraft
This advisory circular (AC) provides aircraft owners, operators, and the public with information and guidance for assistance in compliance with Title 14 of the Code of Federal Regulations (14 CFR) part 91, § 91.21.

Parts 91 and 135 Single Pilot, Flight School Procedures During Taxi Operations
This advisory circular (AC) provides guidelines for the development and implementation of standard operating procedures (SOP) for conducting safe aircraft operations during taxiing to avoid causing a runway incursion. In accordance with the current edition of Federal Aviation Administration (FAA) Order 7050.1, Runway Safety Program, the definition of a runway incursion is, any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft. This AC is intended for use by persons operating aircraft single pilot under Title 14 of the Code of Federal Regulations (14 CFR) parts 91 and 135, and flight schools. The FAA recommends that these guidelines become an integral part of all SOPs, Flight Operations Manuals (FOM), and formal flight training programs.

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.
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.
