Following an RA may result in some minor inconvenience.
Not following an RA may result in your death, and the death of your crew and passengers, and the other aircraft's crew and passengers and maybe even some people on the ground.
Do you want to argue with that?
Well said.
Why not comply with RA demands? If they're followed in a reasonable timeframe it’s generally a gentle manoeuvre. Do you have 360deg vision above and below your aircraft? No. So just do it.
It’s not just your life you’re playing with, it’s all the others mentioned above. The only time I would even consider not following an RA would be if it was going to result in an immediate impact with terrain and how often does that happen?
If ATC said climb or descend you'd comply, yes? So what’s the problem complying with TCAS RAs, considering they have a higher priority than ATC clearances? There should be no confusion here.
