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 to the upper right of the HSI (Figure 2-46). Display
of radar height becomes more sensitive as the height above ground decreases (Table 2-3).

Table 2-3 Radar Altimeter Sensitivity
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 upon reaching (or descending below) the altitude
entered. (Figure 2-48).
