So you will refuse to look out of your windscreen if you have an RA? Good luck if it glitches that day. Leaving everything to the automation is a very dangerous procedure. Following TCAS is standard procedure but looking out the window is still allowed. One day at 4300 ft on a 2,ooo fpm rate of climb I was told level at 4,500 oposite direction traffic 12 o'clock 4,700 one mile. Our 737 couldn't level without possible injuries so I looked out the window and it was clear so expedited the climb to go above traffic. The controller then said your traffic passed below you at 4,500 ft. Sometimes you have to take care of yourself, not rely on automation or controller last minute input. This was before TCAS. TA's and RA's are great safety enhancements if we don't throw out the old look out the window collision avoidance.
