The invention relates to a method for testing a communication connection (1) in a communication network in an aircraft with at least a first controller (7), a second controller (8) and a third controller (9). In order to facilitate rapid and low-resource testing of communication connections in an aircraft, the method according to the invention comprises the steps: generation (14) of a first predefined signal, output (15) of the first signal at a predefined output (x) of the first controller (7) and sending (16) of the first signal to the third controller (9) by the first controller (7); detection (17) of a first incoming signal at a predefined input (y) of the second controller (8) which is connected via the communication connection (1) to the predefined output (x) of the first controller (7), and sending (18) of the incoming signal to the third controller (9) by the second controller (8); comparison (19) of the first predefined signal with the first incoming signal by the third controller (9) and generation (21) of a first identicalness signal if the first predefined signal and the first incoming signal are the same; repetition (22) of the steps with a second predefined signal and generation of a second identicalness signal by the third controller (9) if the second predefined signal and a second incoming signal are the same; output (26) of an enabling signal if the first and the second identicalness signal have been generated.
