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.
