How aerospace systems engineers integrate cybersecurity hazard mitigation into traditional functional safety processes.
Traditionally, safety engineering focused on random hardware component failures (ARP4761), while cybersecurity addressed intentional malicious attacks (DO-326A). In connected electric aircraft, these disciplines must converge.
A cybersecurity vulnerability that could command an actuator hardover must be classified with the same severity as a mechanical jam—Catastrophic (DAL A)—requiring joint safety and security review gates.
By structuring system requirements with unified safety and security traceability, aircraft manufacturers satisfy both functional safety and airworthiness cybersecurity mandates within a single cohesive compliance dossier.
