Acknowledging the SHELL human factors model, authors examine interfaces among components and assess problems created when the model is aligned with modern digitized flight deck systems. Complacency and overreliance on automated systems are evaluated, and cognitive load and potential for degraded situational awareness are examined. Authors present a SHELL overlay demonstrating where particular digitized functions and operations present challenges to operators and markedly influence effective SHELL interactions in highly complex flight deck systems. Human factors contributing to the Asiana Flight 214 accident are examined and correlates identified with the SHELL analysis. Implications for advanced crew resource management are presented, and human centered system training applications are proposed for addressing the workload challenges. Implications for working and prospective memory functions are examined, along with accompanying biases. Potential for adaptive automation technology concludes the SHELL overlay analysis with potential for reducing cognitive overload in the digitized flight deck environment.
