WXR page (for Weather Radar System) is part of the cockpit set of applications. It allows the crew members to adjust the orientation (the tilt angle) of the weather radar system when needed (the main idea being to use this feature only if necessary as, most of the time, the default behaviour is the correct one).
There are three possible states for tilt angle selection: auto adjustment, auto stabilization and setting up manually the tilt angle (as shown on lower part of figure). The upper part allowing changing the mode of the weather radar independently from the tilt selection).
