The invention relates to an aircraft landing gear putting-down position indicating system and an indicating method, the aircraft landing gear putting-down position indicating system comprises a landing gear down lock, down lock microswitches and putting-down position indicating lamps, the down lock microswitches comprise two microswitches, and each microswitch is connected with one putting-down position indicating lamp. The two microswitches are respectively controlled by the position of the undercarriage down lock, when the undercarriage is in the down position, the down lock respectively triggers the two microswitches, the two microswitches are respectively connected with the down position indicating lamp, one of the microswitches and the associated down position indicating lamp are designated as main indicating circuits, and the other microswitch and the associated down position indicating lamp are designated as auxiliary indicating circuits. The other microswitch and the associated putting-down position indicating lamp are standby indicating circuits; putting-down position indicating lamps of main indicating lines of all the undercarriages are arranged on a navigation landing annunciator in a concentrated mode, and putting-down position indicating lamps of standby indicating lines of all the undercarriages are arranged on a standby indicating board of the undercarriages in a concentrated mode.
