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 following table. Use of the GAIN and TILT controls will 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.
