Plain-English Explainer
DO-356A provides methods and considerations for carrying out airworthiness-security activities, including security risk assessment, analysis and assurance.
RTCA describes DO-356A as a methods document used within the airworthiness-security process defined by DO-326A / ED-202A. The core process specification has since advanced to DO-326B, while DO-356A remains the currently published RTCA methods document listed in RTCA's security portfolio.
For electric aircraft with integrated propulsion controls, flight-control networks and maintenance/data interfaces, security analyses can directly affect the safety argument and certification evidence.
