The invention relates to a double-channel aeronautical digital power supply control method. A double-channel aeronautical digital power supply comprises two paths of input power supplies, input contactors, power supply converters and loads, wherein the input power supplies, the input contactors, the power supply converters and the loads are sequentially connected, a connecting contactor is connected between the two paths of loads, and the two power supply converters are mutually connected. The method comprises the steps of input contactor control, product starting voltage-regulating control, output contactor control and logic control of the connecting contactor between two channels. According to the double-channel aeronautical digital power supply control method, the quality of the input power supplies before working can be judged, the quality of output electric energy of the power supplies can be detected, and the loads are protected; and one connecting contactor is additionally arranged between the two chan
