FAA AC 90-114B ADS-B Operations

In May 2010, the Federal Aviation Administration (FAA) issued Title 14 of the Code of Federal
Regulations (14 CFR) part 91, §§ 91.225 and 91.227. This rule requires Automatic Dependent
Surveillance-Broadcast (ADS-B) Out performance when operating in designated classes of
airspace within the U.S. National Airspace System (NAS) after January 1, 2020, unless
authorized by air traffic control (ATC). This advisory circular (AC) provides users of the NAS
guidance regarding how to conduct operations in accordance with §§ 91.225 and 91.227. The
appendices in this AC provide guidance for additional operations enabled by ADS-B, including
ADS-B In.

FAA Notice N8900.525 Revised FAA-Approved Deicing Program Updates, Winter 2019-2020

This notice provides inspectors with information on holdover times
(HOT) and recommendations on various other ground deicing/anti-icing issues. This notice
clarifies guidance regarding reported Aviation Routine Weather Report (METAR) obscurations
to remove potential misinterpretations.
Note: This notice is designed to be used in conjunction with the Federal Aviation
Administration (FAA) Holdover Time Guidelines for Winter 2019-2020. The two
documents complement each other and should be used together for a thorough
understanding of the subject matter.

FAA AC 91-57B Exception for Limited Recreational Operations of Unmanned Aircraft

This AC provides interim safety
guidance to individuals operating unmanned aircraft, often referred to as drones, for
recreational purposes under the statutory exception for limited recreational operations of
unmanned aircraft (Title 49 of the United States Code (49 U.S.C.) § 44809). This AC
restates the statutory conditions to operate under the exception and provides additional
guidance on adhering to those conditions. Per 49 U.S.C. § 44809, recreational flyers may

EASA CM-21.A-D-002 issue 01

The purpose of this Certification Memorandum is to provide specific guidance for certification of external
installations on helicopters, for modifications for which CS 27/29.865 is not applicable. It deals with external
fixtures (see 1.4 Definitions) and devices that are non-extensive in terms of weight, external surface are
and/or volume. Large agricultural kits, external rigid water tanks for fire-fighting operations, collapsible
buckets or external platforms used for Human External Cargo (HEC), hoist and cargo hook installations are
considered to be outside of the scope of this CM.
Additionally this CM provides guidance to ensure the proper classification of design changes involving
external installations and any subsequent modifications to them, either by the original approval holder or
through the STC process by a third party.
Examples of external installations to which this Certification Memorandum is applicable:
 External equipment boxes with fixed equipment (fixed mass and CG)
 Cameras
 Searchlights
 Loudspeakers
This CM focuses on the technical aspects to be considered to certify such installations from the structural
and flight substantiations points of view. Other technical considerations that could affect these installations
(electrical, avionic, environmental, etc.) are not within the scope of this CM.

ED Decision 2019/019/R Update of the acceptable means of compliance and guidance material to the Air OPS Regulation

On 4 September 2019, Commission Regulation (EU) 2019/1384 was published. Said Regulation amends Commission
Regulation (EU) No 965/2012 (the Air OPS Regulation) by introducing new requirements into all Annexes to the
Regulation. The Regulation and consequently this Decision, which contains the related acceptable means of
compliance (AMC) and guidance material (GM), combine the outcome of the following four rulemaking tasks:
— RMT.0516 on an update of the Air OPS Regulation, including an editorial update of AMC & GM and new
provisions on establishment of rules on non-commercial operations with reduced cabin crew on board;
— RMT.0352 on new provisions on the use of aircraft registered on an air operator certificate (AOC) by operators
that are not AOC holders for non-commercial operations or specialised operations, without removing the
aircraft from the AOC;
— RMT.0393 on maintenance check flights; and
— RMT.0561 on in-flight entertainment systems.
In addition to the RMTs mentioned above, this Decision is based on safety recommendations (SRs) regarding air
operations; safety actions deriving from the European Plan for Aviation Safety (EPAS), and amended International
Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs). The main objective is to improve
the level of safety. The amendments are expected to increase safety and ensure alignment with ICAO standards.
