need to press the Start Now button. The only reason use the Start Now button would be if you
wanted to start without going through the start gate or across the start line, or if you had
started but for some reason (GPS issue..?) the ClearNav did not think you had started. Once the
task starts the button changes from Start Now to Exit Task. The Exit Task button is used to exit
the task if you decide to re‐start or abandon the task.
• Next Leg / Turn Here? Button
The Next Leg button is used to move on to the next leg of the task. For example, if you are
currently navigating to the first turnpoint and have just rounded the turnpoint you would press
the Next Leg button to tell the ClearNav to start navigating to the next turnpoint in the task.
The ClearNav will automatically switch to the next leg when you enter the turn cylinder of an
assigned task, but it will not automatically switch when flying an area task – because you will
probably want to continue flying into the turn area rather than moving on as soon as you enter
the turn area. The button changes to a Turn Here? button when you enter into a turn area.
When you select the Turn Here? button the task is redrawn with that point as the turnpoint and
the active waypoint is changed to the next waypoint in the task. After the Turn Here? button is
pressed, it turns into an Undo Turn Here button. Select the Undo Turn Here button to resume
navigation to the calculated ideal turnpoint.
• Resume Task Button
The Resume Task button is used to resume the task after it has been suspended. The task is
suspended any time you start navigating to a non‐task turnpoint. For example, if you are
getting low and use the Selection Box to fly to a nearby airport, the task will be suspended.
When the Resume Task button is pressed the ClearNav will resume navigating to the waypoint
that it was navigating to when the task was suspended.
• Glide To Finish / Glide To Next WP Button
The Glide To Finish button makes it possible to display final glide information around multiple
turnpoints to the finish. The ClearNav will continue navigating to the current task turnpoint,
but the Final Glide Window will no longer display the differential final glide to the next
turnpoint. It will display the final glide around the remaining task turnpoints to the finish. Also,
the Distance Window will show the distance around the remainder of the task. There is no
change in the text description in the Final Glide Window – instead, the Destination Window
changes to “To Finish” to indicate that the final glide calculation is to the finish
point. The other indicator that you are displaying the Glide To Finish number in the Final Glide
Window is that the Glide To Finish button will change into the Glide To Next WP (waypoint)
button. Press the Glide To Next WP button to resume displaying the final glide and distance to
the active task waypoint.
• Achieved Speed
The Achieved Speed is the speed achieved from the start to your current position. It is a good
reference for helping to calculate the Predicted Speed for the remainder of the task, but it is
