ACARS over IP system for non-safety messages
First Claim
1. A communication system in an aircraft, comprising:
- a communications management unit (CMU) that is coupled to at least one safety subnetwork and an Aircraft Communications Addressing and Reporting System (ACARS) over IP (AOIP) computing device;
the AOIP computing device, wherein the AOIP computing device is coupled to at least one non-safety subnetwork,wherein the AOIP computing device determines whether ACARS messages received from the CMU are ACARS safety messages or ACARS non-safety messages;
wherein the AOIP computing device monitors CMU status messages from the CMU;
wherein, 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; and
wherein, 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.

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.

8. A computerized method for transmitting Aircraft Communications Addressing and Reporting System (ACARS) non-safety messages using an ACARS over IP (AOIP) computing device, comprising:
-
determining whether ACARS messages received from the CMU are ACARS safety messages or ACARS non-safety messages; monitoring CMU status messages from the CMU; in response to receiving an ACARS safety message, periodically transmitting a second status message indicating that the AOIP computing device is unavailable; and in response to determining that at least one safety subnetwork is available, stopping periodically transmitting the second status message and transmit a first status message indicating that the AOIP computing device is available. - View Dependent Claims (9, 10, 11, 12, 13, 14)
