APPENDIX E
SYSTEM MESSAGES AND REMOTE ANNUNCIATORS
The CMA-9000 FMS can generate the following types of system messages:
•
System Alert Messages: messages that require immediate pilot action;
•
Maintenance Alert Messages: messages that indicate a particular CMA-9000 FMS failure condition;
•
Maintenance Advisory Messages: messages that do not require immediate pilot action but indicate a
particular equipment failure condition;
•
Status Advisory Messages: messages that do not require immediate pilot action but require pilot awareness;
•
Data Entry Advisory Messages: messages that indicate that the user-entered data is incorrect.
SYSTEM ALERT MESSAGES
System Alert Messages are messages that require immediate pilot action. Alert Messages are the highest
priority scratchpad messages (cannot be typed over or overwritten by any other message type).
Alert messages are displayed in amber color in the scratchpad and on the MESSAGE RECALL page. These
messages disappear automatically when the condition that caused them no longer exists.
Alert messages cause both the CMA-9000 FMS front panel MSG annunciator and the remote MSG annunciator
to illuminate until all messages are cleared/acknowledged by the pilot. Alert messages are cleared (thus
acknowledged) from the scratchpad by pressing the CLR key.
New messages that have not yet been acknowledged are displayed with an asterisk (*) prefix on the MESSAGE
RECALL page. Bringing in view the MESSAGE RECALL page(s) acknowledges all messages at once.
Alert messages have the highest priority and supersede any advisory message or typed-in data displayed in the
scratchpad.
Alert messages that are related to navigation sensor performance are displayed only if the sensor is interfaced
with the CMA-9000 FMS and configured through the CMA-9000 FMS maintenance pages (see Installation
Manual).
Alert messages are prioritized internally by the CMA-9000 FMS, with the highest displayed at the top and the
lowest at the bottom of the MESSAGE RECALL page.
Unless otherwise noted, the CMA-9000 Master Caution is inactive (e.g. FMS is still functional) for all the System
Alert messages.
Collector Alert 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).
