The settings here are for users with AVCS charts from Admiralty Maritime Data Solutions (formerly UKHO). This support will user your chart permits to download the AVCS chart files associated with your permits. This feature will download charts (both initial download and updates).
We do not sell AVCS charts, so you will need to contact an Admiralty agent to purchase the charts. They will need your Settings / S-63 Charts / User Permit to create an account. Once you have your chart permits, install the permits in the Files tab using any of the normal methods for importing files. The AVCSPermits.zip file can be installed directly or you can unzip and install the PERMIT.TXT file it contains.
At most 100MB of charts are downloaded at a time. If you have large numbers of charts, you may need to download in multiple steps. You can also download the charts directly from Admiralty using the link below.
If you do not want to use this automatic download feature, you can instead download the Zip archive files from Admiralty FTP server. If you choose this option, you will also need to manually install updates as needed.
The steps to purchase and use AVCS charts are:
Chart Files : View currently downloaded chart files.
From time to time, you may wish to remove old AVCS update files. After deleting them, be sure to start an Update to download any parts of those files that might still have been needed.
Download Updates : Pressing this triggers an attempt to download or update AVCS charts. You must be connected to the internet. The update continues in the background.
This capability can be used for your initial chart download as well as for periodic updates.
You can see the status being updated as the download proceeds. When complete, a notification is given.
Keep in mind that chart updates can be quite large, depending on the number of cells you have purchased. You may want to wait until you are connected to a high speed internet connection before downloading updates for your charts.
Erase All Admiralty Charts : This button erases all your AVCS chart files, after confirmation. This cannot be undone. You can download the files again. You can erase chart files individually by going to the Charts listing and pressing Edit.
This may be useful when changing accounts to clear out old files. Also, we recommend doing this periodically to reduce the number of update files present on your device.
