An aircraft flight deck audio system, including a central management unit and pilot, co-pilot and third-man terminals. Estimation units estimate the quality of uplink and/or downlink digital signals of the pilot and co-pilot terminals. A control unit is configured such that, when the quality of the digital signals on the uplink and/or the downlink of the pilot or co-pilot terminal is estimated as unsatisfactory, the digital signals intended for the pilot or co-pilot terminal are routed toward the third-man terminal downlink and the digital signals originating from the third-man terminal and present on the uplink are routed toward the output of the pilot or co-pilot terminal. Transceiver units of the pilot, co-pilot and third-man terminals, respectively, transmit the digital signals of the pilot or co-pilot terminal on the third-man terminal downlink and the digital signals on the uplink of the third-man terminal toward the pilot or co-pilot terminal.
