The Emerging & Required DO-326/ED-202-Set Essentials: The Airworthiness Security Process, Methods & Considerations

Thursday 4th November 2021


The DO-326/ED-202 set’s guidance and recommendations are dispersed across all the documents comprising the set, but for establishing airworthiness, the “core” parts of the DO-326/ED-202 set: DO-326A/ED-202A & DO-356A/ED-203A – are to be considered.

This “core” establishes the “Airworthiness Security Process” (AWSP), which is the top level guidance for Airworthiness Security Certification.

The AWSP comprises 7 steps, comprising 14 activities, which include 62 major objectives (combined) to be met, as well as a large number of required artifacts to be produced.

As for the DO-178/DO-254 set development process, the security process is accompanied by integral processes, which, for security, are named “Security Effectiveness Assurance” –comprise 39 objectives, broken down into 118 activities, and are applied as functions of the hierarchical level, severity of consequences and other considerations.

Finally, these processes and methods apply with differing considerations to a variety of development situations, such as – development from scratch, modifications, incorporation of COTS equipment and more.

This detailed tutorial will put all these into their proper places, and clarify the process, methods & considerations for most common cases that require certification, while providing attendees with practical insights and tools to approach this complex process.
