Fault/Failure Analysis For Digital Systems and Equipment

S-18 Aircraft and Sys Dev and Safety Assessment Committee
  • Aerospace Standard
  • ARP1834B
  • Current
Published 2018-02-14 by SAE International in United States
ARP1834 provides general guidance for the selection, approach to, and performance of various kinds of F/FA of digital systems and equipment. Its prime objective is to present several industry-acceptable, cost-effective methods for identifying, analyzing, and documenting digital-equipment failure modes and their effects. The analysis techniques and considerations presented here are directed to digital-equipment hardware faults and failures exclusively. ARP1834 is not intended as an exhaustive treatment of the enormously complex process involved in the analytical failure evaluation of complete digital systems, nor as a universally applicable, definitive listing of the necessary and sufficient steps and actions for such evaluation. ARP4761 provides updated methods and processes for use on civil aircraft safety assessment. When analyzing these types of systems, ARP4761 should be used in lieu of this ARP. ARP1834 addresses the following areas of consideration in the preparation and performance of F/FA's for digital equipment: a Possible Analysis Approaches: Top-Down and/or Bottom-Up (Section 3) b Fault/Failure Modes, as they affect equipment operation and performance (Section 4) c Fault Monitoring Methodology: Reasons for, types of, and effectiveness…

Safety Assessment of Transport Airplanes in Commercial Service

S-18 Aircraft and Sys Dev and Safety Assessment Committee
  • Aerospace Standard
  • ARP5150
  • Current
Published 2013-05-09 by SAE International in United States
This document describes guidelines, methods and tools used to perform the ongoing safety assessment process for transport airplanes in commercial service (hereafter, airplane). The process described herein is intended to support an overall safety management program. It is associated with showing compliance with the regulations, and also with assuring a company that it meets its own internal standards. The methods outlined herein identify a systematic means, but not the only means, to assess ongoing safety. This document does not address the economic decision-making associated with the safety management process. While this decision-making is an integral part of the safety management process, this document addresses only the ongoing safety assessment process. To put it succinctly, this document addresses the “Is it safe?” part of safety management. It does not address the “How much does it cost?” part of the safety management. This document also does not address any specific organizational structures for accomplishing the safety assessment process. While the nature of the organizational structure is significant to the quality of a safety program, this document focuses…

Contiguous Aircraft/System Development Process Example

S-18 Aircraft and Sys Dev and Safety Assessment Committee
  • Aerospace Standard
  • AIR6110
  • Current
Published 2011-12-16 by SAE International in United States
This AIR provides a detailed example of the aircraft and systems development for a function of a hypothetical S18 aircraft. In order to present a clear picture, an aircraft function was broken down into a single system. A function was chosen which had sufficient complexity to allow use of all the methodologies, yet was simple enough to present a clear picture of the flow through the process. This function/system was analyzed using the methods and tools described in ARP4754A/ED-79A. The aircraft level function is “Decelerate Aircraft On Ground” and the system is the braking system. The interaction of the braking system functions with the aircraft are identified with the relative importance based on implied aircraft interactions and system availabilities at the aircraft level. This example does not include validation and verification of the aircraft level hazards and interactions with the braking system. However, the principles used at the braking system level can be applied at the higher aircraft level. The methodologies applied here are an example of one way to utilize the principles defined in…

Guidelines for Development of Civil Aircraft and Systems

S-18 Aircraft and Sys Dev and Safety Assessment Committee
  • Aerospace Standard
  • ARP4754A
  • Current
Published 2010-12-21 by SAE International in United States
This document discusses the development of aircraft systems taking into account the overall aircraft operating environment and functions. This includes validation of requirements and verification of the design implementation for certification and product assurance. It provides practices for showing compliance with the regulations and serves to assist a company in developing and meeting its own internal standards by considering the guidelines herein. The guidelines in this document were developed in the context of Title 14 Code of Federal Regulations (14CFR) Part 25 and European Aviation Safety Agency (EASA) Certification Specification (CS) CS-25. It may be applicable to other regulations, such as Parts 23, 27, 29, 33, and 35 (CS-23, CS-27, CS-29, CS-E, CS-P). This document addresses the development cycle for aircraft and systems that implement aircraft functions. It does not include specific coverage of detailed software or electronic hardware development, safety assessment processes, in-service safety activities, aircraft structural development nor does it address the development of the Master Minimum Equipment List (MMEL) or Configuration Deviation List (CDL). More detailed coverage of the software aspects of…

GUIDELINES AND METHODS FOR CONDUCTING THE SAFETY ASSESSMENT PROCESS ON CIVIL AIRBORNE SYSTEMS AND EQUIPMENT

S-18 Aircraft and Sys Dev and Safety Assessment Committee
  • Aerospace Standard
  • ARP4761
  • Current
Published 1996-12-01 by SAE International in United States
This document describes guidelines and methods of performing the safety assessment for certification of civil aircraft. It is primarily associated with showing compliance with FAR/JAR 25.1309. The methods outlined here identify a systematic means, but not the only means, to show compliance. A subset of this material may be applicable to non-25.1309 equipment. The concept of Aircraft Level Safety Assessment is introduced and the tools to accomplish this task are outlined. The overall aircraft operating environment is considered. When aircraft derivatives or system changes are certified, the processes described herein are usually applicable only to the new designs or to existing designs that are affected by the changes. In the case of the implementation of existing designs in a new derivation, alternate means such as service experience may be used to show compliance.
