What do you do with the TCAS in that situation? Put it in TA?
That was indeed an Ops manual requirement when we first got TCAS, but that was subsequently amended out and we leave it in RA. It's a while since i've done a close parallel visual there but we didn't get any TCAS alerts/warnings last time. Improved software?
There's a new wrinkle - the Airbus Autopilot/Flight Director TCAS RA mode. If AP is engaged, and an RA occurs, the AP automatically performs whatever maneuver is directed by TCAS. So for places where "unwanted RA's" might occur, the only option to prevent unwanted disruption of the terminal area operation is for the pilot to select TA-only beforehand. Already approved on A380, and soon, if not already on A350 and as an option on A320 series.
