FAI Triangle Assistant helps you complete the largest possible FAI Triangle. You don't have to do much to use the FAI Triangle Assistant. Just turn it on and fly is how we tried to design the assistant. Here's how it works. 

 

Turning the FAI Assistant on or off follows the same philosophy as toggling the Map, Waypoints, Airspace, Navboxes etc. It is controlled through the Display Options dialog.

 

                                       


Flying the Free FAI Triangle task

Once the FAI Area is on, you don't have to do much. You are of course required to know at least rougwhich direction you would like to fly to fly a triangle. The larger the triangle you are attempting, the myou will know where to go. FAI Triangle Assistant will simply follow what you are doing. As you fly thfirst leg it won't yet know which way you are going to fly. That is not a problem. The FAI Area will be  drawn on one side of the first leg. If you would like it to be on the other side, simply tap inside the arand it will rotate (provided that "Rotate on click" is enabled in the settings, which - by default - it is). 


Once you have turned your first waypoint, simply continue to fly towards your other waypoint (or rather a larger area where you would like to turn your second waypoint). As soon as the triangle you have flown is deep enough the FAI Area changes. It is not drawn on the longest leg anymore. Instead it is drawn the last leg you have flown. That means it is showing you the way towards the area where you will bable to turn your second waypoint and allow your whole flight to be an FAI triangle.


When you are near your second waypoint you will appreciate some help from the FAI Triangle  optimization navbox, which is available through the list of Navboxes . Place it visibly on the screen know exactly how large the triangle will be if you can finish it home. After you are happy with what yhave done in your second area, head home. The FAI Triangle optimization should not change anymoit's just about getting home. 


The above example focused on an FAI Triangle which has been started from one of its corners. Flyintriangle with the start on the leg is no different. The only difference is that the second point you turn represents the first point from the above example and the third one is the final one from which you fly  home.


Finishing the task

An FAI Triangle is not finished unless you fly back to your start point. One finish fix within 1 km radius  from another fix that occured before turning the 1st waypoint of the optimized triangle is required to finish the task. It may be a single fix if you started your triangle in one of its corners. It is a whole series of fixes between soaring begin and the first waypoint if you started the triangle on one of its legs. 


FAI Triangle Assistant also helps you identify the exact course to fly by always highlighting a 1km  diameter circle around the closest available finish fix.

 

Rotating the area

Sometimes the flight requires much more thinking than the above examples. You may wish to know if  your current leg is long enough already to cover Town X with the FAI Area of your current flight. For this reason you will want to rotate the FAI area from its current position. It can hardly be easier to do simply tap on the FAI Area on the moving map and it will rotate. If you are far enough on the second leg to make it obvious ehich way you are going to fly the triangle, it will rotate around the legs. All this provided ˝Rotate on click˝ is enabled in the settings, which - by default - it is.

 

The FAI Area icons may also be placed on the Command bar if you wish to have quick and constant  access to them in flight. There are options for toggling the FAI Area and Rotating the FAI Area under Menu > Settings > Commands.

 

FAI Triangle Assistant preferences

If you would like to influence the look and feel of the FAI Triangle Assistant you may do so through Menu  > Settings > OLC & FAI Area dialog.  


Example shows kilometer lines for Triangles between 140 - 200 km. If you fly into the violet area, the  triangle will be an FAI triangle.
