A Technical Analysis of Ergonomics and Human Factors in Modern Flight Deck Design I. Introduction Since the dawn of the aviation era, cockpit design has become increasingly complicated owing to the advent of new technologies enabling aircraft to fly farther and faster more efficiently than ever before. With greater workloads imposed on pilots as fleets modernize, the reality of he or she exceeding the workload limit has become manifest. Because of the unpredictable nature of man, this problem is impossible to eliminate completely. However, the instances of occurrence can be drastically reduced by examining the nature of man, how he operates in the cockpit, and what must be done by engineers to design a system in which man and…show more content…
They will be discussed in further detail in another chapter (Hawkins, 249-54). III. System Design A design team should support the concept that the pilot's interface with the system, including task needs, decision needs, feedback requirements, and responsibilities, must be primary considerations for defining the system's functions and logic, as opposed to the system concept coming first and the user interface coming later, after the system's functionality is fully defined. There are numerous examples where application of human-centered design principles and processes could be better applied to improve the design process and final product. Although manufacturers utilize human factors specialists to varying degrees, they are typically brought into the design effort in limited roles or late in the process, after the operational and functional requirements have been defined (Sanders & McCormick, 727-8). When joining the design process late, the ability of the human factors specialist to influence the final design and facilitate incorporation of human-centered design principles is severely compromised. Human factors should be considered on par with other disciplines involved in the design process. The design process can be seen as a six-step process; determining the objectives and performance specifications, defining the system, basic system design, interface design, facilitator design, and testing and evaluation of the system. This model
