The invention discloses an aviation landing positioning system. The system comprises a laser emitter mounted on a roller frame of an aircraft. A laser reflecting apparatus is disposed on a position corresponding to a roller of the aircraft on an airstrip. A laser receiver is also mounted on the roller frame of the aircraft. The laser receiver is connected to a signal input terminal of a MCU through a signal line. A first signal output terminal of the MCU is communicated with an indicator light A through the signal line, and a second signal output terminal of the MCU is communicated with an indicator light B through the signal line. According to the aviation landing positioning system, the purpose that the pilot can accurately know the relative position of a landing gear of the aircraft anda runway, and accurately lands the aircraft in heavy fog weather can be achieved.
