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.
It is critical that you update the data regularly and that you ensure the databases are current prior to conducting flight operations.
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, manufactured by WINTEC filemate (http://www.wintecind.com/features/filemate/usbflashdrives.html). 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 (see Maintenance Mode section on page 6-52). 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 (and some other options for saving that are not discussed here). Rotate the right inner or outer knob to scroll the cursor up and down and then 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. Once the set of items to be loaded has been selected, press the Proceed LSK to start the load.
TIPS AND TECHNIQUES
**Loading Worldwide Nav databases is highly discouraged and should only be uploaded into the IFD when absolutely necessary. It is highly recommended that only the regional nav database for which the aircraft is flying should be loaded into the IFD. See Service Information Letter 606-00182-032 rev. 00 or later.
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.
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. A progress bar will be presented as the loading process proceeds. During the process, various messages may appear and disappear. The progress bar will reset and be updated for each item to be loaded.
Typical upload times are:
Worldwide Obstacles (1.5 MB) – 5 sec
Eastern US Charts (100 MB) – 3min (5xx only)
US Charts (180 MB) – 5 ½ min (5xx only)
Worldwide Charts (430 MB) – 13 min (5xx only)
US Nav Data (8 MB) – 20 sec
Europe Nav Data (10 MB) – 20-30 sec
Australian Nav Data (1.5 MB) – 5 sec
Worldwide Nav Data (15 MB) – 40 sec **See Note Above**
Each IFD Requires Separate Upload In multiple IFD installations, the database uploads must be performed individually for each IFD to be updated. TIPS AND TECHNIQUES Due to some of the upload durations, Avidyne recommends creating a fob for each IFD to be updated so that the updates can happen in parallel and not stacked serially, thereby extending the overall time to accomplish a full update. Once the loading process is complete, the list will be shown with the load status of each item in the list. If an item was not selected, the status will be "Skipped". If an item was successfully loaded, the status will be "OK". If an error occurred, the status will be "ERROR". If all items loaded successfully, a message to that effect will the shown above the list. If not, an error message will be displayed above the list. Note that all of the LSKs along the left side will be removed and that no cursor will be presented. If there is a need to get the cursor and the LSKs back, either remove and reinsert the USB fob, or just change tabs by touching the tab or using the AUX button and then go back to the Update tab. If the load was not successful, either try again using the error message as a guide or contact Avidyne technical support.
