Zusammenfassung: | In a method for testing an audio communication system of an aircraft, it is detected whether a jack plug of a headset is plugged into a jack of the audio communication system. Subject to the condition that no jack plug is detected, an electrical connection is made between an audio output of the jack and a microphone input of the jack by means of a test bridge circuit provided for at the jack. Furthermore, a test input signal is applied to an audio input connected to the audio output of the jack, and a test output signal is tapped off at a microphone output connected to the microphone input of the jack. The test output signal is used to ascertain a functional state of the audio communication system. Furthermore, an aircraft having an audio communication system is described. |
