Don't ever suggest your reaction to a Tcas warning on a check. You will fail!
Any company's SOP in the event of an RA is to ( as the system will tell you ) Monitor Vertical Speed . Any further interpretation is at best misadventure. At worst your bank angle may prevent you from achieving the necessary climb rate.
Kaptin. TCAS II is unreliable in azimuth. TCAS III was being developed ( is it up and running yet? ) to overcome this flaw. It was envisaged that TCAS III would provide lateral as well as vertical commands during an RA.
I am not an ATC'er and if I feel my position threatened it is because there are fellow aviators who don't understand their systems or how to react to warnings from them!
Flap 5 your point was about as relevent as telling an F1 driver to brake for chicanes.
