+Import approach chart files
+---------------------------
+
+Import on Android devices
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you are using an Android device, you must transfer the approach chart file or
+TripKit file to the device and open it there. There are many ways to transfer
+files, but most users will likely do one of the following.
+
+- Download the file on the Android device with a web browser. The browser will
+  then offer to open the file in **Enroute Flight Navigation**.
+
+- Upload the file to a cloud storage service, such as "Google Drive", "Microsoft
+  OneDrive", "Apple iCloud" or a "NextCloud" instance. Connect your device to
+  the service and use a file management program on your device to open the file.
+
+.. note:: TripKits are ZIP files with specialized content. Trying to open a 
+  TripKit file, some file management utilities will automatically unpack the ZIP 
+  file rather than offering to open it in **Enroute Flight Navigation**.  Along 
+  similar lines, GeoTIFF files are image files with specialized metadata and some
+  file management utilities will launch an image viewing application rather than
+  offering to open a GeoTIFF file in **Enroute Flight Navigation**.
+
+  If you encounter problems opening a TripKit or GeoTIFF file, look for an icon
+  or menu item labeled "Open with…".  Some utilities open an appropriate context 
+  menu after a tap-and-hold gesture.
 
-Please contact us if you are aware of other data sources. We will be glad to
-list them here.
+Import on the Linux desktop
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
+If you run **Enroute Flight Navigation** on a Linux Desktop machine, drag and
+drop the file into the app's main window.
 
-Import OpenAir files on Android devices
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-If you are using an Android device, you must transfer the OpenAir file to the
-device and open it there. There are many ways to transfer files, but most users
-will likely do one of the following.
+Manage your approach chart collection
+-------------------------------------
 
-- Download the OpenAir file on the Android device with a web browser. The
-  browser will then offer to open the file in **Enroute Flight Navigation**.
+On the moving map screen, open the main menu and go to "Library/Maps and Data".
+The page "Map and Data Library" will then open. The page has a "VAC" tab listing
+the approach charts. Use the context menus to uninstall charts and retrieve
+basic information.
 
-- Download the OpenAir file to a desktop computer, connect the device to the
-  desktop computer via USB, and then copy the file to the device. Afterward,
-  open the file with a file management app on the Android device.
 
+Use approach charts
+-------------------
 
-Import Maps on Linux Desktop
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Once approach charts are installed, open the main menu and go to "Approach
+Charts". The page "Visual Approach Charts" will then open. The page lists all
+approach charts installed in your device, sorted by distance to the current
+position. Tap on a chart to open "Approach Chart" page, which shows a slightly
+simplified moving map with the approach chart superimposed on top of the usual
+map layer. As usual, tap on the left arrow symbol in the page title to close the
+page and return to the standard moving map display.
 
-If you are running **Enroute Flight Navigation** on a Linux Desktop machine, use
-the file manager to drag and drop the file into the app's main window.
+.. note:: The menu entry "Approach Charts" is only visible if approach
+  charts are installed on your device. If you cannot find the menu entry, 
+  install some approach charts first.
