DO-178C Guide: Introduction to RTCA DO-178 Certification
DO-178C Plans & Standards Templates
Table of Contents
Introduction
DO-178C, also known as Software Considerations in Airborne Systems and Equipment Certification, is a widely recognized standard for the development of safety-critical software in the aviation industry. It provides guidelines and objectives to ensure that software developed for airborne systems meets the stringent safety and reliability requirements.
One of the key aspects of complying with DO-178C is the creation of various plans and standards that define the processes, activities, and artifacts necessary for the development and verification of airborne software. This article delves into the DO-178C plans and standards templates, exploring their purpose, structure, and significance in achieving software certification.
Software Planning Templates
Software Development Plan (SDP)
The Software Development Plan (SDP) template is a crucial document that outlines the overall approach, activities, and resources required for the development of airborne software. It provides a roadmap for the project and sets the foundation for subsequent planning activities. The SDP includes information such as project organization, software life cycle, development and verification processes, configuration management, and quality assurance activities.
Software Verification Plan (SVP)
The Software Verification Plan (SVP) template details the strategies, methods, and tools to be employed during the verification process. It describes how the software requirements will be tested and verified to ensure compliance with the specified objectives. The SVP outlines the verification tasks, including test development, test environments, test procedures, and criteria for determining successful verification.
Software Configuration Management Plan (SCMP)
The Software Configuration Management Plan (SCMP) template provides guidelines for managing the configuration and control of software throughout the development lifecycle. It defines the procedures and tools used for version control, baselining, change management, and release management. The SCMP ensures that software configuration items are properly identified, controlled, and audited to maintain consistency and integrity.
Software Development Standards Templates
Software Coding Standards
Software coding standards define the rules and guidelines for writing source code to ensure readability, maintainability, and adherence to best practices. These standards cover aspects such as naming conventions, code structure, comments, error handling, and software modularity. Adhering to coding standards promotes consistency across the software development team and enhances code quality.
Software Design Standards
Software design standards provide guidance on the architectural and detailed design of airborne software. They define the structure, interfaces, and relationships between software components, ensuring that the design is robust, scalable, and maintainable. Design standards address topics such as module decomposition, data flow, error-handling mechanisms, and design documentation.
Software Test Standards
Software test standards establish the procedures and techniques for testing airborne software. These standards outline the types of tests to be conducted, including unit testing, integration testing, and system testing. They define the test objectives, test environments, test data, and acceptance criteria. Adhering to test standards ensures that software is thoroughly tested and validated to meet the specified requirements.
Conclusion
The DO-178C standard plays a vital role in ensuring the safety and reliability of airborne software. Developing comprehensive plans and adhering to rigorous standards are essential for achieving software certification. The templates discussed in this article, including the Software Development Plan (SDP), Software Verification Plan (SVP), Software Configuration Management Plan (SCMP), Software Coding Standards, Software Design Standards, and Software Test Standards, provide a framework for successful compliance with DO-178C.
By utilizing these templates, software development teams in the aviation industry can establish clear objectives, define robust processes, and create high-quality software that meets stringent safety requirements. Adhering to DO-178C plans and standards not only enhances software quality but also instills confidence in the reliability and airworthiness of airborne systems.
