It has been commented that flying an offset track can improve the odds of avoiding collisions due to the extreme accuracy of navigation systems now. From reading SLOP procedures it would appear that the selected offset is either on-track, 1 nm or 2nm to the right, although I note that there are proposals for other offsets. This seems strange in that I thought the idea was to simulate past generations inherent lack of airway precision. Would it not be more appropriate that the system (or PF) introduce a random (but fixed) right offset during the on-route portion of the flight, lets say between 0 and 2 nm. Can anybody comment as to why specified offsets are preferred?
I realize this is an old thread but seemed the logical place to post.
