because numbers show that with offset you mathematically increase the collision risk. (check ICAO doc if you want the details and the formulaes)
Please send me some details how to find these ICAO formulas.
Wrong in RNP 5 and RNP 1 airspace
Why is it wrong in RNP5, even in RNP1, if 1/4 NM off-set is used, ( IF any of these RNP make you follow an AIRWAY) ?
PS. In any airspace where radar vectors, or direct to somewhere are flown, Off-Sets make no logic and are canceled anyway.
When I wrote "anywhere" I meant anywhere along AIRWAYs...
