Unsolicited Alarm and Information Messages

The EAGLE displays only one alarm per EPAP at a time based on the highest priority. If a single error is detected, the EPAP application sends an error message to the EAGLE terminal to report the active alarm category. If multiple errors are detected, the EPAP application sends an error message to the EAGLE terminal to report the most severe active alarm category.

If multiple alarms of the same severity exist and their severity is the highest alarm severity currently active, a combination alarm code is sent to the EAGLE. The EAGLE issues the appropriate UAM to the operator.

Errors detected in the hardware and software are reported by the following UAMs, which are described in greater detail in the EAGLE Unsolicited Alarm and Information Messages Guide.

• Critical Platform Alarms are reported by the EAGLE in UAM 0370.

• Critical Application Alarms are reported to the EAGLE in UAM 0371.

• Major Platform Alarms are reported to the EAGLE in UAM 0372.

• Major Application Alarms are reported to the EAGLE in UAM 0373.

• Minor Platform Alarms are reported to the EAGLE in UAM 0374.

• Minor Application Alarms are reported to the EAGLE in UAM 0375.

When all error conditions are corrected for all platform and application errors, the operator receives this UAM:

UAM 0250 MPS available.
