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 Table 6-6. 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 Table 6-6.

Table 6-6 Alert Minimum Terrain and Obstacle Clearance Values
During final approach, Forward Looking Terrain Avoidance (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.
