Guidelines for Development of Civil Aircraft and Systems ARP4754B

This SAE Aerospace Recommended Practice (ARP) 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:

Figure 1 outlines the relationships between the various development documents, which provide guidelines for safety assessment, electronic hardware and software life cycle processes, and the system development process described herein.
