Database Status Page

Database Status Page

The “Databases” selection on the “Status” LSK of the SYS tab will display the currently loaded version of the Nav data, Obstacles data, Terrain data and Charts data and will indicate valid date ranges or if/when a given database is expired.

NOTE Database Currency

It is critical that you update the data regularly and that you ensure the databases are current prior to conducting flight operations. Pressing the “Update Databases” LSK will put the IFD into Maintenance Mode where the databases can be uploaded to the IFD.

DATABASE UPDATES

Periodic updates to nav, chart, obstacle, and terrain databases are all made through the USB port on the front of each IFD. Updates must be performed in accordance with 14 CFR Part 43, Appendix A. Note that data updates require the use of Maintenance Mode, which is permitted only on the ground.

NOTE Database Currency

It is critical that you update the data regularly and that you ensure the databases are current prior to conducting flight operations. The table below summarizes the database update periods:

Database Update Cycle

Chart Data 14 days Expiration watermark displayed after 14 days indefinitely until data updated (Jeppesen)

Nav Data 28 days Airport, airway, navaid, airspace, and FMS data (Jeppesen)

Obstacle Data 56 days Displayed on map and used for TA and FLTA functions (Jeppesen)

Terrain Data As required Displayed on map and used for TA and FLTA functions (Jeppesen).

The IFD is shipped from the factory with this database already loaded and updates are anticipated to be a rare occurrence. Use one of the formatted fobs supplied by Avidyne (marked by the Avidyne logo printed on one side). In the event you no longer  have those available, either call Avidyne for a replacement fob (a nominal fee will be charged) or purchase a replacement through other means.

Acceptable alternative USB drives are FAT32 format. It is recommended to use drives between 4GB and 16B capacity.

To perform a data update, ensure the data to be updated is placed onto one of the acceptable USB fobs and then start the IFD in maintenance mode.

Maintenance mode is organized similarly to flight mode using a tabbed interface. Databases are updated using the "Update" tab. If the IFD is powered up in maintenance mode or maintenance mode is entered using the "Update Databases" LSK, then the Update tab will already be selected.

The Update tab in maintenance mode shows a list in the center of the display containing the files on the USB fob. Rotate the right inner or outer knob to scroll the cursor up and down and then I press the knob button to select the item surrounded by the cursor. The cursor can also be moved by touching items in the list and an item can be selected by touching the item surrounded by the cursor. When an item is selected, a checkmark will appear on the right side of the list. Pressing the right knob button or touching an item when the item surrounded by the cursor is already selected will cause the item to be deselected. All items in the list can be selected or deselected at once by pressing the "Select All" and "Un-Select All" LSKs, respectively.

Update tab with items selected Once the set of items to be loaded has been selected, press the Proceed LSK to start the load. 

TIPS AND TECHNIQUES

Select Only Desired Files For Upload If you keep reusing the same fob for database uploads, be sure to either delete all out-of-date and non-desired files or take care in selecting/deselecting files from the IFD display list. Not doing so may extend data upload times considerably by uploading unintended files.

NOTE Do Not Power Off the IFD During Data Update

Cycling power to the IFD during a database update may result in a corruption of the memory device that stores the databases. If this happens, a service action may be required to restore the data integrity. Use of a ground power unit is recommended.
