Track offsets
Ventus,
The quality of an offset is equally and proportionately useless to the equipment of the other airframe involved in the conflict; Big sky theory has more knobs than ever before with increasing accuracy of GPS based nav etc.
Remember direct tracking, User preferred routes, flex tracks etc not flying 'on the airway'. An offset may out you directly nose to nose with someone going to a waypoint early off a SID etc.
Take a 90 degree crossing event, an offset may help, but equally might put you it, when 'on track' might, repeat might work when all the other holes in the cheese line up.
Would you want to be the one on a self initiated offset (without advising ATC) that actually 'casued, the last hole' and the impact?
Cheers
