or inhibits the alert on the PFD, and does not affect the display of the red weather alert target bands shown
on the Weather Radar Page.

GROUND MAPPING AND INTERPRETATION
A secondary use of the weather radar system is for the presentation of terrain. This can be a useful tool for
verifying aircraft position. A picture of the ground is represented much like a topographical map that can be
used as a supplement to the navigation map on the MFD.
Ground Map mode uses a different gain range than Weather mode. Different colors are also used to represent
the intensity levels. The displayed intensity of ground target returns are defined in the table below. Use of the
GAIN
and
TILT
controls help improve contrast so that specific ground targets can be recognized more easily.
As previously discussed, the type and orientation of the target in relation to the aircraft affects the intensity
displayed.
When the weather radar system is in either the Weather or Ground Map mode, the system automatically
switches to Standby mode upon landing.
