When you plan a route, you can request NOTAM for:
- Airports from the Route
- Close/alternative Airports
- FIR regions
You can purchase a one-year subscription to the preflight briefings through http://services.xample.ch/ under "ADDONS - By products groups - SERVICES".
After the purchase of the subscription you have to sync your products and an option in "Tools" menu called "Preflight briefings" will be enabled.
The upper screenshot shows how to request a preflight briefing.
