larger target returns.

You can dene how long time the trail that each target leaves should remain on your radar
panel. You can also turn OFF target trails.
¼ Note: True motion is recommended when using Target trails
Clearing target trails from the panel
When target trails are displayed on the panel, the radar menu will be expanded to include
an option where you can clear target trails from your radar panel temporarily. The target
trails will start to appear again unless you switch them o as described above.
The radar palette
Dierent colors (palettes) can be used to represent detail on your radar panel.
Radar orientation
Radar orientation is indicated on the upper left corner of the radar panel as either HU
(Heading UP), NU (North Up) or CU (Course up).
Heading up

North up
Rotates the radar image with the north direction upwards.
Course up
Rotates the radar image to display the current navigation course directly up.
This option works only when the NSO-II is navigating an active route. If you are not
navigating an active route the heading up orientation will be used until the navigation
function is started.
