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 the following figure. When an RTC alert is issued, a potential impact point is displayed
on the MAP - 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 MAP - TERRAIN-SVS Page. The alert is
annunciated when the projected vertical flight path is calculated to come within minimum clearance altitudes
in the following figure.
