FORWARD LOOKING TERRAIN AVOIDANCE
The Forward Looking Terrain Avoidance (FLTA) alert is used by TAWS and is composed of:
•
RTC
AND
ROC
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 6-10. When an RTC or ROC alert is issued, a potential impact point is displayed on the
TAWS Page.
•
ITI
AND
IOI
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 6-10.

Table 6-10 Minimum Terrain and Obstacle Clearance Values for FLTA Alerts
During the final approach phase of flight, 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.
