out of interest how are TA/RA's displayed on peoples displays. the ac i am on has a very large head down display showing range rings out to a max of 320 nm. TA/RA's are shown as a diamond or dot in varying coulours out to a max range of 40nm. means that when you get a TA or RA you can see exactly where the other ac is in relation to you making it easy to identify and, if good visual, ignore if you can see that there is in fact no conflict
