I usually turn off the XYZ translation when flying, does it still happen when you do this?

If you're trying to shoot down the sights of a gun and you move your head an inch to the left, you're not going to be able to see exactly where you're shooting.

I believe you're stating TrackIR depth translation (eg. XYZ) rather than just tracking X and Y angles.

I strongly prefer looking around the cockpit, looking around when landing, and especially when in a dogfight. Not to also mention, looking around objects that are in my light of sight, such as the rigid bar supports running through the aircraft windshields.

I do not have this gun targeting problem with any other current aircraft. Should be an option to turn-off the gun sight or flight path indicator from being linked to head movements. I believe some enthusiasts enjoy this realism effect with the flight path indicator or gun target within aircraft as I've seen it intermittently utilized within alpha/beta cycles, but they likely do not use TrackIR.

This bug effectively any use of the flight path indicator or gun sights, treating the indicators as mere eye-candy instead.
