Just run the program before you flight, select your departure and destination airports from the the large scrolling menus, select your airplane and cruising altitude, and hit the "OK What can you tell me?" button. The program will scratch it's head for a few moment devising your briefing (as a real Flight Service Station Specialist would!) and then give you your weather briefing in the appropriate language.
Now here is where it gets interesting: If you have downloaded Real-Weather (actual current weather conditions!) from the internet, then you will get an accurate briefing for the flight you have planned, based on the actual weather that really exists! In theory, the briefing you get from Weather-Breifer will be exactly the same as the briefing you would get from a real flight service station if you picked up the phone and called them for real! We used to advocate actually calling a real flight service station weather-briefer before your flights in X-Plane with Real-Weather downloaded from the net, but then the briefer got mad at us since they were busy enough with the REAL pilots... so now we ask you not to do that!
Want to see where you can get Real-Weather to fly in, and get a briefing with in Briefer? See www.X-Plane.com, Real-Weather section... you can download Real-Weather there!
If you do not have Real-Weather downloaded from the net, then Briefer will give you a rather boring prediction: It will simply tell you to expect the weather that is currently stored in X-Plane's preferences! A boring prediction for sure, but an accurate one... until you change the weather in X-Plane!
