When the distance line is displayed the line length (in nautical miles) and its
rotation angle (default 90
o
) may be changed by clicking in the Rhumb Line
fields and either entering the required values using the online keypad, or by
moving the cursor left or right when the text is in edit mode (green).
The position and length of the line may be changed directly on the display
by moving the cursor over the start and end dots.
With the cursor shown as a bidirectional arrow indicator, hold down the left
key and use the trackball to move the start or end dot to the required
position. To fix the position, release the left key.
As the length of the line is increased or decreased the Great Circle NM
value (read only data) changes to reflect the length shown in the Rhumb
line.
To remove the distance line from the display, close the Distance Line
window.
