OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
MAINTENANCE ADVISORY MESSAGES
Maintenance advisory messages are messages that do not require immediate pilot action but that indicate a
particular equipment failure condition:
• Displayed in white on the MAINT MESSAGES page.
• Displayed on the scratchpad unless an associated collector message exists and is active (until
acknowledged).
• Lowest priority scratchpad messages (can be typed over and overwritten by any other message type).
• Unless otherwise noted, the FMS Master Caution is inactive (e.g. FMS is still functional) for all the
Maintenance Advisory messages.
• Collector messages are messages that combine several fault conditions into a single alert message. (e.g.
AIR DATA LOST combines ADC1 FAILED and ADC2 FAILED Maintenance Advisory messages).
