Air management and control method and system for redundancy aircraft management computer software, computer program and storage medium

The invention provides an air management and control method for redundancy aircraft management computer software. Data are stored to a storage module in real time; and a PMU unit is added to receive a remote control instruction, and enters a management and control process comprising the following steps: step 1, judging the type of the instruction, and if the instruction is a restart instruction, skipping to step 2; if the instruction is the upgrading instruction, skipping to step 3; step 2, sending a restart instruction to CPU software with a specified redundancy, sending key data to the PMU unit, unloading the CPU software, reloading the CPU software into a memory after unloading, and starting the CPU software; step 3, sending the upgrading instruction to the CPU software with the specified redundancy, sending the key data to the PMU unit, obtaining the CPU software of the new version from the link, unloading the original CPU software, and after unloading is completed, putting the CPU software of the new ver
