The invention relates to an airplane double-source redundancy pressure supply brake valve and a control method, a main pressure supply source is connected with a pressure supply port of a main oil source switching valve, an oil return port of the main oil source switching valve is communicated with main pressure supply return oil, and an oil return port of the main oil source switching valve is communicated with a main oil return port of an oil return switching valve; a backup oil return opening of the oil return conversion valve is communicated with an oil return opening of the backup oil source switching valve, a brake oil return opening of the oil return conversion valve is communicated with brake return oil, an oil return opening of the backup oil source switching valve is communicated with backup pressure supply return oil, and the backup pressure supply source is connected with a pressure supply opening of the backup oil source switching valve. A control port of the oil return change-over valve is communicated with a working port of the backup oil source change-over valve, the working port of the backup oil source change-over valve is communicated with the state change-over valve through two pipelines, one pipeline is communicated with a control port of the state change-over valve, and the other pipeline is communicated with a backup pressure supply port of the state change-over valve. A working port of the main oil source switching valve is communicated with a main pressure supply port of the state switching valve, and a working port of the state switching valve is communicated with the airplane wheel brake.
