A warning circuitry (100) with a warning light circuitry (102) and a buzzer circuitry (104) for an exterior door (300) of an aircraft (400) is provided. The warning light circuitry (102) comprises a first logic gate (108) adapted for receiving a first, a second, a third, and a fourth input signal (124a-d); a second logic gate (110) adapted for receiving a fifth, a sixth, and a seventh input signal (124e-g); a third logic gate (116) electrically connected to the first (108) and second logic gate (110); and a warning light (118) electrically connected to the third logic gate (116). The first logic gate (108) is adapted for providing a first output signal (126a) to the third logic gate (116) upon receiving the first, the second, the third, and the fourth input signals (124a-d). The second logic gate (110) is adapted for providing a second output signal (126b) to the third logic gate (116) upon receiving the fifth, the sixth, and the seventh input signals (124e-g). Therein the third logic gate (116) is adapted for triggering the warning light (118) upon receiving the first (126a) or the second output signal (126b).
