Sample Aviation Essay Paper on SHELL Model


The SHELL mode is a safety device developed by Elwyn Edwards in 1972 to indicate the interface involved between the machine systems, flight crew, software and the entire the airspace environment.  Furthermore, the SHELL model was developed to identify probable security risks concealed between the interaction of the systems, persons, and the entire airspace atmosphere. The SHELL name was initiated from its initial letters that stance for Software, Hardware, Environment, Liveware, and Liveware. Software stands for the procedures training and checklist. The Hardware entails the machine system and the equipment (Daganzo, 2014). The Environment refers to the conditions appropriate for its operation, While Liveware entails the interaction surrounding human, environment, software, and hardware. The last Liveware refers to the human interaction within and outside the workplace. From the definition of its initial letters, the SHELL model involves the human to human facet of human conduct in aviation and the human to machine interaction.

As a training equipment, the SHELL model can be used to help improve training interventions in the aviation organization and the efficiency of the aviation firms to prevent aeronautics errors (Jansen, Engel, Hagen, Navratil & Signoracci, 2014). SHELL mode can also be applied as a licensing tool in clarifying the human performance, abilities and therefore promoting competency to be considered as a safety management aspect. In addition, the SHELL model can be significant in understanding the human systemic factors during the functioning audits with the motive of reducing errors and promoting safety as a safety analysis device. The SHELL model acts as an outline for data collection regarding human performance during investigations analysis and aviation incident as proclaimed by the International Civil Aviation Organization. Relatively, the SHELL model system must be adapted and matched properly with the organization system for the model to represent the human variations and limitations in performance. And so, avoiding collapses in the whole aviation system.
