DO-178C Training Crash Course, Software Considerations in Airborne Systems and Equipment Certification
The DO-178C standard defines a set of objectives for software to be certified for use in airborne systems.
In DO-178C “software” pertains to all drivers, BSP, RTOS, libraries, graphics and the application software – in other words, any executable aspect that is loaded into memory during execution.
Software testing means ensuring that the lowest level detailed requirements are accurately implemented, paths are covered according to their criticality level, and full traceability is provided.
Organizations can reduce risks and effort with a verification approach to support the DO-178C objectives, such as:
- Iterate and refine system requirements by creating an executable specification
- Define architecture and confirm your design choices for robustness and maintainability leveraging modeling and simulation
- Demonstrate code and executable coverage through back-to-back testing and end-to-end traceability from requirements to tests
- Automate model and code review activities
- Reduce testing activities by using formal methods
The FAA, EASA and Transport Canada approve all commercial software-based aerospace systems. Through DO-178C these certification authorities emphasize that achieving compliance needs to be done in all aspects of development.
Planning, for example, is critical. You need to plan what you’re going to deliver to market and when — and how you’ll be compliant in your processes. This means you need to gather requirements. And you need to make sure those requirements account for the standard.
Then there’s development, which should be top-of-mind during development processes. This means:
- Requirements should be clearly defined
- Test cases should be developed from requirement
- Code should be written to satisfy those requirements
- Tests should satisfy test cases and show that requirements are met
Verification processes also help prove you’ve satisfied compliance requirements. The three big things that need to be verified: requirements, code and tests.
DO-178C Training Crash Course Description
DO-178C Training Crash Course provides the knowledge required to reduce DO-178C risks and costs, while also enhancing the quality of the software during avionics development. During this intensive hands-on training, participants will learn the best practices for real-life software development and how to stay away from common DO-178C errors.
The DO-178C, which is Software Considerations in Airborne Systems and Equipment Certification, is the main international standard for commercial avionics software development. RTCA/DO-178C is the fourth-generation standard for the commercial airborne software. The United States Federal Aviation Administration recognized it in 2013.
DO-178C gives suggestions to produce effective airborne systems and equipment software. Agreement with the objectives of DO-178C is the key tools to meet airworthiness requirements and obtain approval of software used in civil aviation products.
Through DO-178C training crash course, you will learn aircraft safety, systems, software planning, software requirements, and software design/code/test. The whole environment of aviation avionics software development will be discussed briefly including but not limited to DO-178C’s relationship to other industry standards including the SAE standards ARP-4761 for Safety and ARP-4754A for Systems Development.
DO-178C training crash course presents the fundamental concepts behind DO-178B/C avionics certification. It also discusses the differences between DO-178B and DO-178C, with the focus on how to use the guidance in the Object-Oriented Technologies and Related Techniques supplement (DO-332). You also will learn how to best apply the Ada language and GNAT Pro tool fits to agree with the certification objectives.
The majority of this training is dedicated to hands-on activities and practical exercises with real-world cases. Once the participants learned the basics, concepts, requirements, and guidelines of DO-178C standard and its associated components, they will get to use them in the templates provided in the class. Attendees will learn about the best practices of DO-178C applications.
This intensive training course includes interactive lectures, labs, individual/small group activities, and hands-on workshops.
