FORWARD LOOKING TERRAIN AVOIDANCE

Reduced Required Terrain Clearance (RTC) and Reduced Required Obstacle Clearance (ROC)

alerts are issued when the aircraft flight path is above terrain, yet is projected to come within the minimum
clearance values in Figure 6-88. When an RTC alert is issued, a potential impact point is displayed on the
TERRAIN-SVS Page.

Imminent Terrain Impact (ITI) and Imminent Obstacle Impact (IOI) alerts are issued when the

aircraft is below the elevation of a terrain or obstacle cell in the aircraft’s projected path. ITI and IOI alerts
are accompanied by a potential impact point displayed on the TERRAIN-SVS Page. The alert is annunciated
when the projected vertical flight path is calculated to come within minimum clearance altitudes in Figure
6-88.
