Description
This document provides recommendations for the development of aircraft and systems, taking into account aircraft functions and operating environment. It provides practices for ensuring the safety of the overall aircraft design, showing compliance with regulations, and assisting a company in developing and meeting its own internal standards. These practices include validation of requirements and verification of the design implementation for safety, certification, and product assurance.
The guidelines in this document were developed in the context of U.S. Title 14 Code of Federal Regulations (14 CFR) Part 25 and European Union Aviation Safety Agency (EASA) Certification Specification (CS) CS-25. They may be applicable in the context of other regulations, such as 14 CFR Parts 23, 27, 29, 33, and 35, and CS-23, CS-27, CS-29, CS-E, and CS-P.
This document addresses the development cycle for aircraft and systems that implement aircraft and system functions. It does not include detailed information on the following subjects and references:
- Software development; refer to EUROCAE ED-12C/RTCA DO-178C.
- Electronic hardware development; refer to EUROCAE ED-80/RTCA DO-254.
- Integrated modular avionics development; refer to EUROCAE ED-124/RTCA DO-297.
- Airworthiness security process; refer to EUROCAE ED-202A /RTCA DO-326A.
- Safety assessment processes; refer to EUROCAE ED-135/ARP4761A/.
- A process for accomplishing in-service safety assessment is described in SAE ARP5150A and SAE ARP5151A or in other documents such as the guidance material of EASA Part 21 (GM21) when required by applicable regulation. In this document, wherever references to SAE ARP5150A/ARP5151A are made, the reader should understand this also implies EASA Part 21 (GM21).
- Master Minimum Equipment List (MMEL) or Configuration Deviation List (CDL) development; refer to applicable regulatory guidance from the applicable Certification Authority.
- Aircraft structure and aerodynamics development.
PURPOSE
The guidelines herein are industry best practices for the development of aircraft and of systems. Modern aircraft typically comprise a large integrated environment consisting of multiple systems with significant dependencies and interactions. Frequently portions of these systems are developed by separate individuals, groups, or organizations. These systems require design discipline and systematic development to ensure that safety and operational requirements can be fully realized and substantiated. Adherence to these guidelines is recommended for development of all aircraft systems, especially those that may contribute to failure conditions with the potential to affect safety.
The contents are recommended practices and should not be construed to be regulatory requirements. For this reason, the use of words such as “shall” and “must” is avoided except if used in the context of an example. It is recognized that alternative methods to the processes described or referenced in this document may be available to an organization desiring to obtain certification.
This document provides neither guidelines concerning the structure of an individual organization nor how the responsibilities for certification activities are divided. No such guidance should be inferred from the descriptions provided.
