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database is current and the active database is out of date, the display will upload the standby database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'.
Loading a standby navigation database:
1) With the system OFF, insert the SD card containing the new navigation database version into the top card slot
of the MFD.
2) Verify that an SD card is inserted in the bottom slot of each PFD and the MFD.
3) Turn the system ON. A prompt similar to the following is displayed.
4) Press the YES Softkey. The navigation database is copied to the SD card in the bottom card slot of the MFD.
5) After the navigation database files are copied to the bottom SD card, the display will appear as shown in Figure
B-4.
