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 Figure 10-48. 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 the either the
Weather or Ground Map mode, the system automatically
switches to Standby mode.
