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 aircraft' s
groundspeed is below 120 knots or when the flaps are down. In all other conditions while the traffic system
is providing surveillance, Level B (greater) TA sensitivity is used to assess TA threats.
