HAZARD AVOIDANCE
TA ALERTING CONDITIONS
The traffic system automatically adjusts its TA sensitivity level to reduce the likelihood of nuisance TA
alerting during flight phases likely to be near airports. Level A (less) TA sensitivity is used when the radar
altimeter (if equipped) indicates own aircraft is below 2000' AGL. In all other conditions, Level B (greater)
TA sensitivity is used to assess TA threats.
