HAZARD AVOIDANCE
The system displays the altitude vertical trend as an up/down arrow (for speeds greater than 500 fpm in
either direction) to the right of the intruder symbol.
TA ALERTING CONDITIONS (GTS 800)
The GTS 800 traffic system automatically adjusts its TA sensitivity level to reduce the likelihood of nuisance
TA alerting when the aircraft is more likely to be near an airport. The system uses Level A (less) sensitivity
when the height above terrain is at or below 2,000' AGL. If the height above terrain is unavailable, Level A
sensitivity applies when the ground speed is less than 120 knots. In all other conditions, Level B (higher)
sensitivity applies.
