AIRCRAFT DATA NETWORK, PART 1, SYSTEMS CONCEPTS AND OVERVIEW

2019-06-20
CURRENT
ARINC664P1-2
The purpose of this document is to provide an overview of data networking standards recommended for use in commercial aircraft installations. These standards provide a means to adapt commercially defined networking standards to an aircraft environment. It refers to devices such as bridges, switches, routers and hubs and their use in an aircraft environment. This equipment, when installed in a network topology, can optimize data transfer and overall avionics performance.

OBSOLESCENCE MANAGEMENT STRATEGIES FOR COMMERCIAL AIRCRAFT

2019-05-14
CURRENT
ARINC662-1
The purpose of this document is to establish guidelines that should be observed during initial design, production, and maintenance of aircraft components, and to present short-term and long-term strategies to minimize the costs and impacts associated with decreasing availability of components.

TIMELY RECOVERY OF FLIGHT DATA (TRFD)

2021-08-06
CURRENT
ARINC681
The difficulty in locating crash sites has prompted international efforts for alternatives to quickly recover flight data. This document describes the technical requirements and architectural options for the Timely Recovery of Flight Data (TRFD) in commercial aircraft. ICAO and individual Civil Aviation Authorities (CAAs) levy these requirements. The ICAO Standards and Recommended Practices (SARPs) and CAA regulations cover both aircraft-level and on-ground systems. This report also documents additional system-level requirements derived from the evaluation of ICAO, CAA, and relevant industry documents and potential TRFD system architectures. It describes two TRFD architectures in the context of a common architectural framework and identifies requirements. This report also discusses implementation recommendations from an airplane-level perspective.

WIP
AIR6198
This activity is focused on more electric and all electric type power systems for air vehicles. The scope of which includes source, distribution and user contributions to electrical power quality, failure modes, coordination, system reliabilty and robustness, impacts of being flight critical and the gaps which exist in present standards and guidance documents.

USE OF MODELING AND TOOLS FOR AIRCRAFT SYSTEMS DEVELOPMENT – A STRATEGY FOR DEVELOPMENT ASSURANCE ASPECTS WITH EXAMPLES

2013-04-30
WIP
AIR6276
This AIR addresses the use of Software tools to supplement or automate human activities in the development of systems, but not the hardware or software items within those systems. If a systems development tool is also used in the scope of hardware or software item development, for that usage it would then become subject to the guidance presented in DO-254 and DO-178B/C, respectively.

Guidelines for Repair Process Evaluation of Fiber Reinforced Composite Bonded Structure

2014-01-29
WIP
AIR6292
The SAE Aerospace Information Report (AIR) is intended to be used as a process verification guide for evaluating implementation of key factors in bonded repair of fiber reinforced composite structure in a repair shop environment. The guide will be used in conjunction with a regulatory approved and substantiated repair, and is intended to promote consistency and reliability.

Using STPA During Development and Safety Assessment of Civil Aircraft

2018-02-13
WIP
AIR6913
This AIR will provide a basic understanding of STPA and how it can be applied to development and safety assessment of civil aircraft. It will explain, by way of an example, the information needed to begin STPA, the expected STPA outputs, and the phases of aircraft development and safety assessment that can be supported by STPA.

Design of Durable, Repairable, and Maintainable Aircraft Composite Structures

2016-02-25
WIP
AIR6902
This guidebook will assist in the design and integration of composite commercial aircraft structures that exhibit improved durability, maintainability and repairability. For international use by composite aircraft component designers, this book identifies problems that have occurred with various composite components and provides potential problem-solving recommendations. Written primarily for composite design engineers, Design of Durable, Repairable, and Maintainable Aircraft Composites should also prove valuable to those in structural engineering, materials and processing, product support, advanced product development, systems engineering, technical services, and maintenance operations.

Standardized composite training program

2019-12-04
WIP
AIR6671
SAE CACRC has produced several standards, each representing the best-practice, recommended minimum training syllabus for the aforementioned target groups. The purpose of this document is to promote the use of these SAE standards, particularly for developing training programs for employee training, qualification in airlines and maintenance organizations, and as reference in regulatory guidance material. It summarizes, as a quick reference, the content of each training document and its relation to and interaction with other training documents. Thereby it allows users to select the appropriate training documents and syllabi to establish a comprehensive, sequential training program build-up customized to the specific needs of the aforementioned functions (see figure). This document does not intend to introduce new training content/syllabus.

Human Considerations for Functional Hazard Assessments

2022-05-02
WIP
AIR7127
Clarify the role of the human considerations in Functional Hazard Assessments by identifying the sufficient input information regarding those considerations from the development process, how failure conditions may use that information, and what information the safety assessment process provides to other processes, particularly Human Factors, to assure those aspects of failure conditions are valid.

Reporting of Damage to Composite Structure

2021-03-29
WIP
AIR7509
To create Guidance on the essential information/data that is needed to correctly assess damage and document the damage. A guidance document is proposed as the initial step in which it is documented what essential information is required for a composite repair with the aim to reduce to number of back and forward communications, improve the documents to define damage such as mapping, damage descriptions, sketches, pictures. CACRC Procedures Task Group will be drafting the document.

COMPOSITE INSPECTOR TRAINING COURSE TO ENHANCE PROFICIENCY AND IMPROVE RELIABILITY

2018-07-24
WIP
AIR7491
Increased use of advanced composite structural materials on aircraft has resulted in the need to address the more demanding quality and non-destructive testing procedures. Accordingly, increased utilization of solid laminate composites is driving changes to airline NDT training requirements and greater emphasis on the application of accurate NDT methods. Modules, including an introduction to composite materials, composite NDI theory and practice, special cases and lessons learned, have been produced in addition to various hands-on NDT exercises. A set of proficiency specimens containing realistic composite structures and representative damage has been designed in order to reinforce teaching points of the course and “test” inspector’s proficiency. Extensive details of the course modules, hand-on exercises and the proficiency specimens are all presented in this report.
