How to use the approach charts?
From Settings, you can choose to open the approach charts manually or auto, for all airports in the route, only for departure and arrival or for just the nearest airport from current position.
Approach charts can be opened by selecting a waypoint on the map. Tap on the airport waypoint information to display all the options available.
Another way is by tapping "Waypoint" and type under "Quick Search"
The available approach charts for this specific airport is listed at the bottom. Simply tap on the desired approach charts and it displays on the Moving Map.
The PDF documents will be also stored in the 'Document Browser', where you will be able to search by ICAO code Airport and open them.
