FLIGHT INSTRUMENTS 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).
