About the Backup Navigator Alarm

The Backup Navigator Alarm alerts the bridge to an unacknowledged alarm by trans-
ferring the alarm within the TCS to the BNWAS.
For unacknowledged alarms that require output of the Backup Navigator Alarm, the
TCS sends the Backup Navigator Alarm to the BNWAS. (Power failure of the TCS
does not cause output of the Backup Navigator Alarm.)
The Backup Navigator Alarm is released in the following conditions in IEC 62605
Ed. 2 complying autopilots:
• If, within 30 seconds of the alarm's release, the alarm has not been acknowledged,
has not been temporarily silenced and the alarm condition has not been rectified.
• If, within 30 seconds of the alarm's release, the alarm has not been acknowledged,
has not been rectified but has been temporarily silenced, then the following applies.
When the silencing has expired, the Backup Navigator Alarm acts as if the alarm con-
dition has just occurred. Any further silencing does not result in further delay of the
Backup Navigator Alarm. The silencing mentioned here is the temporary silence, re-
activating the aural announcement, after 30 seconds.
After all the alarms associated with Backup Navigator Alarm activation have been ac-
knowledged or rectified, the Backup Navigator Alarm is deactivated. Acknowledge-
ment can occur locally, remotely, or by deactivating track control.

Waypoint-related indications in the Route Information box

The text "GoSEA Appr. Enabled" or
"GoAW Appr. Enabled" appears in the

edge the Alert "150 Early Course Change
Indication". See Note 2.
When you acknowledge the waypoint ap-
proach alert, the text "GoSEA Turn En-
abled" or "GoAW Turn Enabled" appears in
the [Route Information] box.
During a turn, the text
"GoSEA Turn" or "GoAW Turn" appears in
the [Route Information] box.
Note 1: When you approach the last waypoint, the Alert "30850 End of Track" (For
IEC 62605 Ed.2 complying autopilots the alert name is "End of Track") appears. If you
acknowledge Alert 30850 when the Autopilot is in the NAVI* mode, the route steering
is automatically stopped and the system shows Alert "30851 Auto Pilot Mode Con-
flict". Route steering is deactivated until the NAVI* mode is selected again at the Au-
topilot. To return to the route steering, the ship's heading must be set toward the next
waypoint and the ship must be inside the channel limits. Otherwise, an alert is given.
