The invention belongs to the field of aircraft aeronautical manufacturing, and relates to a method for installing a standby magnetic compass of an aircraft. The method is characterized in that aninstallation plane is selected as a horizontal calibration plane, and when a measuring tool cannot be placed on the installation plane, an auxiliary flat plate larger than the installation plane is placed on the installation plane to serve as the horizontal calibration plane for horizontal calibration. An installation datum line is manufactured by means of an airplane symmetrical structure near an installation plane, a scribed line mark is manufactured according to the installation datum line, and a standby magnetic compass is installed according to the scribed line mark. According to the method, the horizontal installation precision and the course installation precision of the standby magnetic compass can be effectively ensured, the subsequent compass error calibration step can be simplified, and the calibration time
