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. When an RTC alert is issued, a potential impact point is displayed on the TAWS 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 TAWS Page. The alert is annunciated when the
projected vertical flight path is calculated to come within minimum clearance altitudes in the table.

Table 6-14 FLTA Alert Minimum Terrain and Obstacle Clearance Values
During final approach, FLTA alerts are automatically inhibited when the aircraft is below 200 feet AGL
while within 0.5 nm of the approach runway or below 125 feet AGL while within 1.0 nm of the runway
threshold.
