Abstract: On the basis of a theoretical framework,executive process interactive control (EPIC), a computational model of virtual pilot was developed to simulate cognitive process of complex task performance. By Comparing the outcome of model simulation with experiment results of human beings,a high goodness of fit was found,thus it supported the following key conclusions:(1) It validated the computation model for mimic flight and it bolstered up the claim of the present simulation theoretical model. The performance of human pilot could be well predicted by the presented model. (2) This simulation technique in the present research provided us with feasible approach to mental processing of complex tasks.

Key words: EPIC model, simulation, virtual pilot
