Abstract
A communication system in an aircraft is described. The communication system includes a CMU that is coupled to at least one safety subnetwork and an AOIP computing device. The AOIP computing device is coupled to at least one non-safety subnetwork. The AOIP computing device determines whether ACARS messages received from the CMU are ACARS safety messages or ACARS non-safety messages. The AOIP computing device monitors CMU status messages from the CMU. In response to the AOIP computing device receiving an ACARS safety message, the AOIP computing device periodically transmits a second status message indicating that the AOIP computing device is unavailable. In response to determining that at least one safety subnetwork is available, the AOIP computing device stops periodically transmitting the second status message and transmits a first status message indicating that the AOIP computing device is available.
