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).

If a navigation database loader card is inserted into the top SD card slot of a display, and an SD card is in the 

bottom slot, the system will prompt the user (upon on-ground power up) as to whether the database should 
be stored on the bottom SD card as the standby database.  If the user responds affirmatively, the system will 
copy the navigation database from the top SD card to the bottom SD card.  As long as the bottom SD card 
remains in the card slot, this standby navigation database will be available for the system to use as the active 
database as soon as it becomes effective. 

The system checks the active and standby databases upon (on-ground only) power-up.  If the standby 

database is current and the active database is out of date, the display will upload the standby database into the 
active internal database location.  Uploading the standby database to the active location takes approximately 
45-55 seconds.  The pilot is alerted that the update is complete by a system alert message, ‘NAV DB UPDATED’. 

With the system OFF, insert the SD card containing the new navigation database version into the top card slot 
of the MFD.

Verify that an SD card is inserted in the bottom slot of the PFD and the MFD.

Turn the system ON.  A prompt similar to the following is displayed.

Press the YES Softkey.  The navigation database is copied to the SD card in the bottom card slot of the MFD.

After the navigation database files are copied to the bottom SD card, the display will appear as shown in Figure 
B-4.
