Use the lower-right knob to modify the MacCready setting. Refer to Chapter 5.5.4.2 for
more details.
It is also highly recommended to check the safety altitude setting. Refer to Chapter 5.1.1 to
find out how to define the safety altitude.

Preparing a Task

While it is advisable to prepare the task properly before taking off and thus avoid mistakes
made in a haste, all the following actions, preparing, editing, loading and saving, can be
done while in the air. But then, the task cannot be declared in the air.
There is only one task. This task will be automatically declared in the IGC file on
takeoff. The task can also be modified during flight but any changes will not be
written to the IGC file.
There are currently three methods to create a task. Further methods will be available in
future releases.
Read way point and task file from SD card and load a saved task.
Load a similar task and modify it.
Enter task manually.
It is very important to check the task prior to takeoff. Check the turning points
sequence, distance between points, bearings and total task distance. Visually
check the task and observation zone geometry in the map view.

Assigned Area Tasks (AAT)

In fact an assigned area task is a speed task where the task distance is not exactly defined.
The pilot has limited influence on the task geometry due to larger observation zones
(assigned areas). The pilot decides how far he will fly into each individual area to reach best
average task speed and not finishing the task earlier than the designated task time.
An assigned area task has the same structure as other tasks and all known methods to enter
are the same as described. The only differences are larger observation zones having a
specific geometry.

Use the ZONE button (see chapter 5.7.3) to modify the individual
