OK..
Sorry if I was not "clear"
Wiley was saying that it "needs" to get sorted, continueing that line, I agreed.
What I meant by my "first hand experience" was that I had seen how the modern accuracy actually put us directly over and under opposite direction traffic, and I mean exactly. The discussion in the cockpit at that time was exactly about that.
As an ATC, I watch daily (continuously) how, on airways, opposite direction traffic cross over each other on the exact same track (in opposite directions).
I also think that the off-set tracks (on direct routings between waypoints and on airways) should be built in to the navigational equipment.
I am not a pilot, but I see the advantages of this method.
I do not see how my statements were "Bizare"
Best Regards.
