This blog will help to design , develop and test bug free software with expertise engineers with their views and suggestions. This could be helpful to overcome Do-178B certification issues and provide quality products.
The avionics cockpit group industry requires that safety-critical software be assessed according to strict cockpit group United States Federal cockpit group Aviation Administration (FAA) and Europe Joint Aviation Authority (JAA) guidelines before it may be used on any commercial airliner. ARP 4754 and DO-178B are guidelines, which are used both by the companies developing airborne equipment cockpit group and by the certification authorities.
ARP cockpit group 4754 [ARP4754] was defined in 1996 by the SAE (Society of Automotive Engineers). This document discusses the certification aspects of highly integrated or complex systems installed on aircraft, taking into account the overall aircraft-operating environment and functions. cockpit group The term “highly-integrated” refers to systems that perform or contribute to multiple aircraft-level functions.
The guidance material in this document was developed in the context of Federal Aviation Regulations (FAR) and Joint Airworthiness Requirements (JAR) Part 25. In general, this material is also applicable to engine systems and related equipment.
ARP 4754 addresses the total life cycle for systems that implement aircraft-level functions. It excludes specific coverage of detailed systems, software and hardware design cockpit group processes beyond those of significance in establishing the safety of the implemented system. More detailed coverage of the software aspects of design are dealt with in RTCA document DO-178B and its EUROCAE counterpart, ED-12B. Coverage of complex hardware aspects of design are dealt with in RTCA document DO-254 [DO-254] .
ED-12/DO-178B [DO-178B/ED-12B] was first published in 1992 by EUROCAE (a non-profit organization addressing aeronautic technical problems) and RTCA (Requirements and Technical Concepts for Aviation). It was written by a group of experts from certification authorities and companies developing airborne software. It provides guidelines for the production of software for airborne systems and equipment. The objective of the guideline is to assure that software performs its intended cockpit group function with a level of confidence in safety that complies with airworthiness requirements.
These guidelines specify: • Objectives for software life cycle processes. • Description of activities and design considerations for achieving those objectives. • Description of the evidence cockpit group that indicate that the objectives cockpit group have been satisfied.
ARP 4754 and DO-178B are complementary guidelines: ARP 4754 provides guidelines for the system level processes. DO-178B provides guidelines cockpit group for the software development processes. I am explaining the above standards for entry level engineers in avionics domain, the above both standards are very important in airborne system & software development.
