1.2.12-7 Speech Message Priority

A speech message priority system should be established such that more critical messages override the presentation of messages having lower priority.

Additional Information:
If two or more incidents or malfunctions occur simultaneously, the message having the higher priority should be given first. The remaining messages should follow in order of priority. In the event of a complete subsystem failure, the system should integrate previous messages via electronic gating and report the system rather than the component failure.
