I had an issue with this. I was flying the Su-27 with English HUD. A person was flying towards me in a valley. I locked him up in BORE, with no "F" on HUD, but it was a TK (My first one ever :doh::cry:)
Well, a little wile later, I was RTB, and another person was coming straight at me at 12 o'clock. I cocked him up in BORE, no"F." I checked it BVR any way and it was friendly... is this a bug? or does it not work head on?
BTW, i did see the F in other situations, but not head on.
I feel so bad about this mistake, and I want to know if it was my mistake, or the computers. (If it was my mistake, I'll take full responsibility)
