Table 6-18 Terrain-SVS Alerts Summary
FORWARD LOOKING TERRAIN AVOIDANCE
The Forward Looking Terrain Avoidance (FLTA) feature of Terrain-SVS compares the projected flight path
as derived from GPS data with terrain features and obstacles from the terrain and obstacle databases. The
system issues visual annunciations and voice alerts when the projected flight path conflicts with terrain or
obstacles.
The projected flight path is a calculated area ahead of, to the sides, and below the aircraft. The size of
the projected flight path varies based on factors including ground speed (the path ahead is larger when the
ground speed is higher), whether the aircraft is level, turning, or descending, and the proximity to the nearest
runway along the current track. As the aircraft approaches the runway, the projected flight path becomes
narrower until the system automatically disables FLTA alerts or the pilot manually inhibits them.
There are two types of FLTA alerts, Reduced Required Terrain/Obstacle Clearance (RTC or ROC respectively)
and Imminent Terrain/Obstacle Impact (ITI or IOI respectively).
