The invention discloses an aircraft stall warning device which comprises a stall warning port, an air pressure switch and a warning signal output device. One end of the stall warning port is arranged on the outer side of the leading edge of an aircraft wing, the other end of the stall warning port extends into the aircraft wing, an air inlet port, located on the outer side of the aircraft wing, of the stall warning port is round, and an air outlet port, located in the aircraft wing, of the stall warning port is provided with a threaded connector or a pagoda nozzle connector. The air inlet port is communicated with the air outlet port through a pipeline; the air pressure switch is arranged on a cabin driving operation table, the air pressure switch comprises a pressure inlet, a pressure switch comprising a pressure contact piece is arranged in the air pressure switch, and the pressure inlet is communicated with an air outlet port of the stall warning port through a pipeline. The device is simple in structure, the manufacturing cost and the later maintenance cost of the aircraft can be effectively reduced, and the stall calibration cost of the aircraft can be effectively reduced through a convenient calibration mode in flight.
