DUAL NAVIGATION DATABASES
The dual navigation database feature allows each display to store an upcoming
navigation database on the bottom SD card so that the system can automatically load it
to replace the active database when the new database becomes effective (the next cycle
becomes available seven days prior to its effective date).
Uploading the standby database to the active location takes approximately 45-55
seconds.
Loading a Navigation Database
1)
With the system OFF, insert the SD card containing the navigation database
update into the top card slot of the desired PFD or the MFD.
2)
Verify that an SD card is inserted in the bottom slot.
3)
Turn the system ON.
4)
At the prompt, if it is desired to update the standby navigation database
on the bottom SD card, select the YES Softkey and proceed to step 6. If it
is desired to update the active navigation database, select the NO Softkey
and proceed to step 5.
5)
At the next prompt, select the YES Softkey to update the active navigation
database.
6)
After the update, the display starts in normal mode.
7)
Repeat steps 1-6 for the remaining displays.
8)
Verify the effectivity of the active navigation database in each PFD and the
MFD on the AUX-System Status Page.
AUTOMATIC DATABASE SYNCHRONIZATION
The automatic database synchronization feature automatically transfers the database
from a single SD database card to the SD cards on each PFD and the MFD to ensure
that all databases are synchronized throughout the system. After power-up, the system
compares all copies of each applicable database. If similar databases do not match, the
most recent valid database is automatically copied to each card in the system that does
not already contain that database.
NOTE:
The 9-arc second terrain database may take as long as 100 minutes to
synchronize using this method. Therefore the user may want to transfer the data
using a PC, or connect the system to a ground power source while performing
the database synchronization.
