|61-140A||AFS-800||Autorotation Training The purpose of this advisory circular (AC) is to describe enhanced guidelines for autorotations during helicopter flight training. The Federal Aviation Administration (FAA) has found a need to raise awareness of the risks inherent in performing autorotations in the training environment, and in particular, 180-degree autorotations. In this AC, the FAA recommends procedures that will mitigate safety risk during autorotations. This information is intended to supplement information about autorotation training found in the current editions of the Helicopter Flying Handbook (HFH), FAA-H-8083-21, and the Helicopter Instructor’s Handbook (HIH), FAA-H-8083-4. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, of conducting autorotation training for proficiency or in consideration of the requirements to be issued an Airman Certificate under Title 14 of the Code of Federal Regulations (14 CFR) part 61. You may use alternate methods for training if you establish that those methods meet the requirements of the HFH and FAA practical test standards (PTS).||08-31-2016|
Flight Standards Service Schedule of Charges Outside the United States
This advisory circular (AC) transmits an updated schedule of charges for services of Federal Aviation Administration (FAA) Flight Standards Service (AFS) aviation safety inspectors (ASI) outside the United States. Rulemaking action to Title 14 of the Code of Federal Regulations (14 CFR) part 187, Docket No. 27809; and Notice 94-24, Fees for Certification Services and Approvals Performed Outside the United States, established the methodology for determining these charges. The rulemaking established that the FAA would publish these fees in an AC.
|39-10||AIR-100||Alternative Methods of Compliance This advisory circular (AC) presents guidance for persons seeking approval of an alternativemethod of compliance (AMOC) to an airworthiness directive (AD). This AC also providesanswers to common questions regarding AMOCs.||09-14-2016|
|125-1A||AFS-800||Operations of Large Airplanes Subject to 14 CFR Part 125 This advisory circular (AC) sets forth one means that would be acceptable to the Administrator to assist persons in complying with the requirements of Title 14 of theCode of Federal Regulations (14 CFR) part 125. It also provides, in Chapter 2, a test of applicability for operations which may be subject to part 125.||09-15-2016|
Specification for Obstruction Lighting Equipment
This AC contains the FAA specification for obstruction lighting equipment. Effective 12 months after the date of this circular, only that equipment qualified per this specification will be listed in AC 150/5345-53, Airport Lighting Equipment Certification Program. No re-testing will be required for existing equipment where test standards are unchanged from the previous version of this AC.
|20-140C||AIR-130||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.||09-28-2016|
Onboard Recording of Controller Pilot Data Link Communication (CPDLC) In Crash Survivable Memory
This advisory circular (AC) provides guidance material for applicants seeking an airworthiness approval for aircraft with an installed Data Link Recording (DLR) system that records Controller Pilot Data Link Communications (CPDLC). This AC describesan acceptable means, but not the only means, to gain design approval of your data link communication recording system. However, if you use the means described in the AC, you must follow it in its entirety.
In this AC, we focus on data to be recorded and logical recording point locations for storing CPDLC messages in onboard crash-survivable memory. These logical point locations, also called observation points, are physical locations within airborne avionic architectures deemed ideal for recording system data sources, as defined in Section 7.1 of this AC.
