Reducing the risk of aviator-multifunction display interface problems with human factor models and optimization design methods.
Multifunction display and control systems (MFDCSs) in modern cockpits use computer-generated graphics and symbology that have integrated and largely replaced the myriad discrete electromechanical flight instruments found in older aircraft. While much is known about the physical and visual properties of MFDCSs, less is known about which human factors are the most important for optimum design and use. Reports in the literature indicate that poor MFDCS design can adversely influence flight performance. However, current MFDCS content design methods do not quantify the relative importance of different cognitive and psychomotor factors. This article discusses the need for practical human factors-oriented MFDCS design tools to optimize the distribution of systems information and functionality. Such advances may lead to better designed MFDCSs that reduce aircrew workload and stress and improve flight performance during both routine and emergency procedures.
