Abstract: |
For the problem that the failure level of integrated avionics function combination will upgrade with the increase of the number of integrated functions,this paper analyzes the host function scheme of the integrated avionics system of the typical aircraft type,selects the proper analysis strategy that is applicable to avionics system features,realizes the confirmation and analysis of the effect of the functional combination failure by comprehensively considering the common cause problem,multiple backup system resident,system design features,information dependence and other factors.By taking the host scheme of the Boeing 787 aircraft as example,the validity of the analysis method is shown. |
