o
Automatically corrects for curvature of the earth.
o
Pilots can choose among display options as desired.

Internal Topography Database
o
Used to remove ground clutter from weather displays and to
remove weather returns from the MAP display.

More sensitive weather detection for more accurate weather depiction
o
Improved long-range performance.
o
3D scanning detects more weather close to the aircraft as
compared to other weather radar systems.

Differentiation of weather in and out of path of the aircraft
o
In ALL or ALL WX mode, weather that is far above or below the
aircraft’s flight path ( Off Path ) is displayed in a different pattern
than On Path weather.
o
In ON PATH or PATH WX mode, the display of weather that is
Off Path is suppressed. Only the weather that is relevant to the
flight path is shown.
o
In ELEVN mode, view horizontal slices through the weather in
1,000-foot increments, from ground level to 60,000 ft.

Weather/Turbulence Ahead Alerting
o
Alerts the pilot when significant weather or turbulence is detected
on the flight path trajectory.

Map mode for identification of terrain features
o
Use MAP mode for identifying prominent terrain features, such as
coastlines, lakes, and large built-up urban areas.
The RDR-4000 is a technically advanced system, but as always, there
are physical limitations to consider.

The use of a topography database results in a significant reduction in
ground returns. However, the database is not aware of man-made
reflectors such as buildings at airports and cities. Therefore, it is
possible that not all ground clutter will be eliminated.

The antenna beam is very narrow at close ranges and widens
significantly with range. Therefore, the resolution and accuracy of
weather reflectivity is better at ranges closer to the aircraft.
