RADAR ALTIMETER

When the radar height (the aircraft altitude above ground level detected by the radar altimeter) is between
zero and 2500 feet, the current value is displayed in green above the selected course (Figure 2-46). Display of
radar height becomes more sensitive as the height above ground decreases (Table 2-3).
When the radar altimeter is selected as the altitude source for the minimum descent altitude alerting function
(Figure 2-47), the color of the radar height changes to yellow (Figure 2-48).
