Y'All,
This entire thread seems to be totally entranced with the possible
conflict of aircraft on a heading/course. Whereas, the most likely
conflict is in altitude between IFR and VFR supposedly flying with 500
feet of FAA separation.
...snip...
To me the probability of a midair is more likely to altitude error than
heading error. The odds of having two such aircraft with hemispheric
accumulative opposite errors in altitude sufficient to cause a midair is
unlikely but more likely than an opposite heading midair. .



Actually, if the two of them are not on the exact same location
horizontally, the odds of a conflict because of altitude error is zero.

While there is some remote possibility of being in the same location
horizontally at the same time while crossing tracks, the potential to be in
the same location horizontally is much greater when they are navigating
reciprocal tracks between the same two waypoints.
