For the previous evaluation of equipment system effectiveness,people pay more attention to the technical ability of equipment and ignore the influence of human on equipment effectiveness.Based on the analysis of the characteristics of the effectiveness of aviation equipment system,a human factor based equipment system effectiveness evaluation method is proposed for the equipment qualification test requirements under the new situation.The human factor coefficient model for evaluating the effectiveness of the aviation equipment system is established,which effectively solves the problem of not fully considering the influence of human factors in the previous system effectiveness evaluation and makes the equipment system effectiveness assessment results more closely related to the actual use in the field.
