DO-278A Training Software Integrity Assurance 

Better known as the “Software Integrity Assurance” standard, DO-278A is a strong guideline comprising both recommendations and assessable objectives.

DO-278A is intended for use in developing ground-based systems (containing software) which are involved with aircraft operations.

The benefits of software integrity in the aviation industry – and all industries – are considerable. Even though it can be a challenge to achieve, integrity can have profound benefits for your code, because it ensures that:

  • Coding defects are identified and addressed sooner.
  • Code remains agile, modular and maintainable.
  • Cyber-threats are mitigated.
  • Code development is well documented and organized.
  • Code regulations and industry standards are met.
  • Analytics are clear, detailed and accessible.

Software integrity is important as it demonstrates the safety, security and maintainability of your code. What’s more, ensuring that code has high integrity is especially important for software that needs to comply with coding standards and aviation industry regulations.

Today, DO-278A is a standalone document.  Although it describes many activities, processes, and objectives that are in common with DO-178C, it is no longer necessary to use them side-by-side.

The growth and complexity of airborne systems requires the elaboration of specific standards for software certification, mainly due to the characteristics of safety and reliability. As a consequence it is also been necessary to improve the corresponding verification processes including the techniques that facilitate checking compliance with these required features.

DO-278A Training Course Description

DO-278A training provides you with the knowledge, concepts, principals, history, standards, and tools relevant to DO-278A. Learn about  DO-278A, Software Integrity Assurance Considerations for Communication, Navigation, Surveillance and Air Traffic Management (CNS/ATM) Systems

We will teach you how to create, develop, and verify avionic software to DO-278A/ED- 109A. Also, we will cover the supplements of DO-278A/ED-109A to deliver extra support for model-based design, object-oriented programming and official techniques. DO-278A training will also discuss the logic behind the goals in DO-278A/ED-109A, the Tool Qualification document (DO-330/ED-215) and the supplements including DO-331/ED-216, DO-332/ED-217 and DO-333/ED-218.

DO-278A Training

DO-278A training is delivered in two separate modules; lectures and practical activities. Participants will learn all the theoretical material needed to develop and implement DO-278A via fun, interactive lectures and then they will experience what they have been taught through practical activities. The Practical module includes several labs, group activities, and hands-on seminars.
