And another thing: for all the 'aces' out there. As we all (should) know TCAS RA manoeuvres are practiced and examined through the mandatory recurrent LPC system here in the UK. The TRE will be looking for the correct response to the simulated RA. Why not try ignoring the RA and tell the examiner that you are going to visually miss the traffic? See how that goes. I find it unbelievable that professional pilots do not understand the imperative of correct response to an RA. It disturbs me that I share the same airspace.
