Map
While in horizontal scan mode, this feature can be used as a tool to determine
areas of possible inaccuracies in displayed intensity due to weakening of the
Traffic
radar energy. This weakening is known as "attenuation." The radar energy
Terrain
weakens as it passes through areas of intense precipitation, large areas of lesser
precipitation, and distance. Issues with the radome will also attenuate the radar
Weather
energy. All these factors have an effect on the return intensity. The more energy
that dissipates, the lesser the displayed intensity of the return. Accuracy of the
Nearest
displayed intensity of returns located in the shaded areas are suspect. Make
maneuvering decisions with this information in mind. Proper antenna tilt

management should still be employed to determine the extent of attenuation in
a shaded area.
