Capt Windsock, I have to disagree with your (perhaps flippant?) comment, (“ offsetting is great as long as you are the only aircraft doing it. ” posted 16 June 2001 15:20 )
The fact is, the safety margin doubles if all opposite direction traffic offsets one mile right; ie, if the navigation equipment is accurate (and the indisputable fact is, it is - very, very accurate), the separation between opposite direction traffic becomes 2 NM, because each aircraft is 1NM right of the airway centreline.
