Correct MAS. The A380 automated TCAS / RA response feature from the operational perspective prescribes a rigid FMA adherance. In the unlikely event that the automation does not work there is a back up sop to fly the manoeuvre manually. The automation is incorporated in both f/d and a/p modes. Whether you are flying a fully automated A380 /A350 or a less sophisticated aircraft you must follow the RA even @ aircraft certified ceiling. Regardless of 'taking a chill pill' any alternative is ill - informed drivel. As I stated before, any professional pilot on this site who thinks differently why not 'debate' the point with your TRE on your next LPC.
