6.3.2 MONITOR 2/6 – OOOI, COMM, and Message Status
This page displays read-only status of the discretes and annunciators associated with OOOI,
COMM, and message status. Maintenance often uses this page to verify annunciators, chime, and
any fail status for connected devices. The left side shows discrete inputs; the right side shows
outputs.
Note If new/unread messages exist, the CPDLC MSG and ACARS MSG are active and the
annunciators for ATC and ACARS are lit. There is also a chime pulse duration
configuration setting that may provide aural annunciation for the items on this page.
