ABSTRACT:
The invention relates to a method for testing a communication connection in a communication network in an aircraft with at least a first controller, a second controller and a third controller. The method includes the steps: generation of a first predefined signal, output of the first signal at a predefined output of the first controller and sending of the first signal to the third controller by the first controller; detection of a first incoming signal at a predefined input of the second controller which is connected via the communication connection to the predefined output of the first controller, and sending of the incoming signal to the third controller by the second controller; comparison of the first predefined signal with the first incoming signal by the third controller and generation of a first identicalness signal if the first predefined signal and the first incoming signal are the same; repetition of the steps with a second predefined signal and generation of a second identicalness signal by the third controller if the second predefined signal and a second incoming signal are the same; output of an enabling signal if the first and the second identicalness signal have been generated.
