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. In a fixed-gear installation, Level A (less) TA sensitivity
is used when the groundspeed is less than 120 knots; Level B (greater) TA sensitivity applies in all other
conditions. In a retractable-gear installation, the system applies Level A TA sensitivity when the landing
gear is extended and/or the groundspeed is less than 120 knots; Level B TA sensitivity applies in all other
conditions.
