Book excerpt: When digital technology is employed to perform some function aboard aircraft, the designer documents the technology and the applicant presents a package to the Certification Engineer (CE). Typically, the package might include design and test specifications, test plans, and test results for the system. This package assures the CE that the designer has properly developed and validated the system. Software Quality Metrics (SQM) may be used during the software (SW) development and testing. SQM technology attempts to quantify various quality-oriented factors, such as reliability and maintainability. The SW developer determines the quality factors that are important to the application. SW Metrics that correlate to these factors are used on the code to determine to what extent these factors have been reached. Based on the results, the developer determines whether the SW meets the requirements set for it and how well the SW will perform. This technical report documents the results of a study conducted to analyze SQM as they apply to the code contained in avionic equipment and systems. This report is intended to provide an in depth explanation of how SQM may be applied and interpreted.

Download or read book Digital Systems Validation Handbook Volume 3 Design Test and Certification Issues for Complex Integrated Circuits written by and published by . This book was released on 1996 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter provides an overview of complex integrated circuit technology, focusing particularly upon application specific integrated circuits. This report is intended to assist FAA certification engineers in making safety assessments of new technologies. It examines complex integrated circuit technology, focusing on three fields: design, test, and certification. It provides the reader with the background and a basic understanding of the fundamentals of these fields. Also included is material on the development environment, including languages and tools. Application specific integrated circuits are widely used in Boeing 777 fly-by-wire aircraft. Safety issues abound for these integrated circuits when they are used in safety-critical applications. Since control laws are now executed in silicon and transmitted from one integrated circuit to another, reliability issues for these integrated circuits take on a new importance. This report identifies certification risks relating to the use of complex integrated circuits in fly-by-wire applications.

Download or read book Validation of Digital Systems in Avionics and Flight Control Applications Handbook written by Ellis F. Hitt and published by . This book was released on 1983 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this handbook is to identify techniques, methodologies, tools, and procedures in a systems context that may be applicable to aspects of the validation and certification of digital systems at specific times in the development and certification portion of the system life cycle. The application of these techniques in the development of discrete units and/or systems will result in a completion of a product or system which is verifiable and can be validated in the context of the existing regulations/orders for the government regulatory agencies. The handbook uses a systems engineering approach to the integration and testing of software and hardware during the design, development, and implementation phases. The handbook also recognizes and provides for the evaluation of the pilot's workload and utilization of the new control/display technologies, especially when crew recognition and intervention may be necessary to cope with/recover from the effects of faults or failures in the digital systems. In summary, the handbook: (1) Identifies and presents the issues related to design, development, and implementation of software based digital systems; (2) identifies specific approaches applicable to all aspects of the verification and validation procedures, at specific times in the development and certification portion of the system life cycle, (3) provides the government regulatory agencies (especially the Federal Aviation Administration (FAA) as well as the industry with a set of tools/procedures, in a systems engineering context which may be of value in the validation/certification process.

This book was released on 2018-07-08 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on one prepared as a chapter for the FAA Digital Systems Validation Handbook (a guide to assist FAA certification specialists with advanced technology issues). Its purpose is to explain the use of formal methods in the specification and verification of software and hardware requirements, designs, and implementations; to identify the benefits, weaknesses, and difficulties in applying these methods to digital systems used in critical applications; and to suggest factors for consideration when formal methods are offered in support of certification. The presentation concentrates on the rationale for formal methods and on their contribution to assurance for critical applications within a context such as that provided by DO-178B (the guidelines for software used on board civil aircraft); it is intended as an introduction for those to whom these topics are new.

This book was released on 2018-07-25 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report has been prepared to supplement a forthcoming chapter on formal methods in the FAA Digital Systems Validation Handbook. Its purpose is as follows: to outline the technical basis for formal methods in computer science; to explain the use of formal methods in the specification and verification of software and hardware requirements, designs, and implementations; to identify the benefits, weaknesses, and difficulties in applying these methods to digital systems used on board aircraft; and to suggest factors for consideration when formal methods are offered in support of certification. These latter factors assume the context for software development and assurance described in RTCA document DO-178B, 'Software Considerations in Airborne Systems and Equipment Certification, ' Dec. 1992.
