The virtual evaluation of the Ergonomics layout in Aircraft cockpit

Abstract

The cockpit layout is evaluated by simulating human-computer interface in civil cockpit with the Cockpit Ergonomics layout and Assessment system (CEA air-V1.0). Evaluation is carried out by three steps: a) Data input: import the original digital model of cockpit which is simplified by 3D software (such as CATIA, UG, SOLIDWORKS, 3DSMAX .etc), into CEA and then 5%, 50%, 95% percentage manikin of Chinese pilots; Input the data of evaluation scenario and pilots' operation postures. b) Ergonomic analysis and evaluation: adjust pilot' s manikin eye point to the designed eye point; the accessibility and visibility of cockpit layouts main instrument panel, control display of anterior central pedestal control stand, central pedestal control stand, top control board, sun-shield, left and right-hand side console, steering column and pedal are evaluated; design eight postures in accordance with flight mission and evaluate the upper limb postures and joint movement postures in the eight types of operation postures by using CEA . c) Data output: output the data of 3D scenario, evaluation results and operation postures etc. by CEA. The deficiencies are found in the design of cockpit layout by evaluation results. This method can be used in the virtual evaluation of preliminary cockpit layout' saving resources in prototype test and improve the cockpit design efficiency.
