The AC describes methods for maintaining aircraft in order to maximize both a safety and economic benefit.
Obstruction Marking and Lighting with Change 1
This Advisory Circular (AC) sets forth standards for marking and lighting obstructions that have been deemed to be a hazard to navigable airspace.
|91-70B||AFS-400||Oceanic and Remote Continental Airspace Operations This advisory circular (AC) contains general information and detailed guidance for operators planning flights in oceanic and remote continental airspace, including authorizations needed for operations outside the continental United States (CONUS). This includes Performance-based Navigation (PBN) and Special Areas of Operation (SAO). The Federal Aviation Administration (FAA) revised this AC to focus on the evolving operations in airspace where air traffic control (ATC) provides procedural control. This AC is laid out in a chronological format, beginning with foundational information, followed by information on the training, authorizations, and equipment required to operate most efficiently in this airspace, and finishing with flight planning, flight execution, and contingency operations guidance. Our goal is to provide you with a template to guide you through planning and executing flight operations through oceanic and remote continental airspace. Information related to international operations in specific locales has been removed from this AC due to its transitory nature. Some region-specific information has been incorporated into the North Atlantic (NAT), West Atlantic Route System (WATRS)/Gulf of Mexico/Caribbean, and Pacific (PAC) Resource Guides (NAT PDF, West Atlantic, Caribbean, and Gulf of Mexico PDF, and PAC PDF). These online resource guides, along with the FAA Notices to Airmen (NOTAM) Domestic/International, provide the most current information available to pilots, aircraft dispatchers and other operational control personnel preparing for oceanic and international operations.We have also included hyperlinks to many documents, available free or for purchase. The dynamics of oceanic and remote continental airspace operations are such that they are constantly evolving, and it is incumbent on you, the operators, to closely monitor any changes.||10-04-2016|

Guidelines for Design Approval of Aircraft Data Link Communication Systems Supporting Air Traffic Services (ATS)
This AC provides guidance material for applicants seeking an airworthiness approval for aircraft with an installed data link system intended to support air traffic services (ATS) data communication. It identifies specific configurations of aircraft data link systems for applicants seeking approval for type certificates (TC) and supplemental type certificates (STC) in order to facilitate operational approvals. Appendix A of this AC provides a list of related documents. Appendix B of this AC contains a list of applicable acronyms. 1.2 This AC describes an acceptable means, but not the only means, for you to gain airworthiness approval for aircraft data link system equipment. However, if you use the means described in this AC, you must follow it in all important respects. 1.3 The term “must” is used in this AC to indicate a mandatory requirement driven by regulation that is to be followed when using the guidance in this AC. The term “should” is used in this AC to indicate a recommendation and not a requirement when using the guidance in this AC. Since this AC represents an accepted means of compliance, an applicant seeking an alternative to any requirement or recommendation within this AC will need to be discussed with the Aircraft Certification Office (ACO) in order to achieve a common performance level with the AC.

|00-6B||AFS-400||Aviation Weather This advisory circular (AC) was published by the Federal Aviation Administration (FAA) Flight Standards Service (AFS), with contributions from the National Weather Service (NWS). The publication began in 1943 as CAA Bulletin No. 25, Meteorology for Pilots, which at the time contained weather knowledge considered essential for most pilots. As aircraft flew farther, faster, and higher, and as meteorological knowledge grew, the bulletin became obsolete. It was revised in 1954 under a new title, The Pilots’ Weather Handbook, and updated again in 1965. In 1975 it was revised under its current title.||08-23-2016|

This AC provides information for PAHs in accordance with the regulations cited in Title 14 of the Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products and Articles. For the purposes of this AC, manufacturing facilities includes production certificate (PC) extensions, associate facilities, and suppliers located outside the United States. Before approving a PAH’s request to use manufacturing facilities outside of the United States, the FAA must consider certain factors that may impact the FAA’s ability to administer the requirements of part 21 that could potentially cause the FAA an undue burden. This AC outlines the necessary information the PAH should submit to the FAA as part of the PAH Project Initiation Plan included as appendix A to this AC (hereafter referred to as a “project plan”) to demonstrate that the proposed activity will not cause an undue burden||08-01-2016|
Airport Field Condition Assessments and Winter Operations Safety
This AC provides guidance to assist airport operators in developing a snow and ice control plan, assessing and reporting airport conditions through the utilization of the Runway Condition Assessment Matrix (RCAM), and establishing snow removal and control procedures.
For implementation purposes, all certificated airports must submit revised Snow and Ice Control Plans to the FAA no later than September 1, 2016, for approval. The Federal NOTAM System is the primary means of conveying airport condition information by certificated and federally obligated airports. Effective October 1, 2016, the Federal NOTAM System will incorporate the new reporting criteria and methodology contained in this AC.
