Av, both the 330 & 350 have auto TCAS. It literally just flies the RA.
Auto Emerg. Descent on the 350, simple version: press AED button, pull speedbrake. If you don’t respond to a high cab. altitude (unconscious etc), a countdown timer starts then it does it for you. Descends at VMO-5 to 40nm Grid Mora corrected for temp/isa, turns right to intcpt a ~ 3nm offset, squawks 7700, points TCAS below. Interrupts the whole thing for TCAS if necessary. Works a treat.
Both types have yaw rate control for EFATO, not TAC. 350 also applies aileron deflection on operating side to control yaw.
