To complete this type of tasks, you need to do some preflight preparation.
1. Enter the task you will be flying.
You will need to go to the Menu > Task dialog. Use the keypad to enter waypoint names in list view. Type first few characters, then use left and right keys to complete the selection.
After you have entered the task waypoints, check that waypoint sectors are setup correctly. At each of the waypoints, click on the Edit button to open Edit point dialog. Setup these values to fly FAI records or badges:
- Start: Direction = Next, Radius1 = 0.5km, check Line only checkbox.
- Waypoints 1-3: Direction = Symmetric, Radius1 = 3km, Angle1 = 45° (the rest is zero or not unselected)
- Finish: Direction = Previous, Radius1 = 0.5km, check Line only checkbox.
2. Start the task in flight.
Look at the screen to see where the start line is in order not to miss it. You will get a sound warning telling you that you have successfully crossed the start line. After you have crossed the start line a box appears where the start time is displayed. To start navigating on the task, press the Start Time box. Navigation is moved to the first waypoint of the task and statistics runs.
- Map pages to see where you are
- Navboxes to see the flight parameters you are interested in
- Statistics to see what you have done
- Airspace warning to keep yourself out of trouble
- Goto dialog to find nearest airports etc.
4. Final glide
Here's a suggestion. Flying final glides is the most comfortable when you use the Required L/D and Current L/D navboxes. What they do is they show the required L/D to the finish line and current L/D you are doing at the moment. You are on glide slope when Current L/D is higher than Required L/D. The calculation already includes reserve altitude. The nice part is that it is insensitive to the MC setting, glider polar, wind calculation, setting for bugs and ballast. All of them can be wrong when you try to math through the glider polar.
Current L/D however is pragmatic - it tells you what you are doing. Required L/D is pragmatic as well. It tells you what you should be doing. If Current L/D is higher than the Required one you are doing good. If it looks like you can keep going like that, you are doing great.
Have fun making those final glides!
