IFALPA October 2010
"While headline figures revealed by the data gives some encouragement; by the end of 2009 some 40% of flights were using an offset, there is still a concern that the distribution remains unbalanced with 60% of flights on centreline, 30% at 1nm offset and 10% 2nm offset (at 30W) this compares with the optimum 33/33.5/33.5 distribution that will deliver the greatest risk reduction."

SLOP...never found it necessary, and neither have the Captains that work for us, either.
Therefore, not done in our outfit....and, not likely to start anytime soon.

The chances to die in the head on crash on an airway are very low, but I guess the relatives of 155 dead people from that GOL flight (including the crew, which decided that SLOP is unnecessary) will not appreciate it.
Sarcasm on.

Sarcasm off.

I'm shocked.

That regulation was written long before GPS. If either aircraft in the Brazil midair had used 1 mile right both would have passed in the night, neither knowing how close they came. Any pilot not using an off set in certain areas of the world are either negligent or ignorant or both.
What about FAR 91.181?
Sec. 91.181
Course to be flown.
Unless otherwise authorized by ATC, no person may operate an aircraft within controlled airspace under IFR except as follows:
(a) On a Federal airway, along the centerline of that airway.
(b) On any other route, along the direct course between the navigational aids or fixes defining that route. However, this section does not prohibit maneuvering the aircraft to pass well clear of other air traffic or the maneuvering of the aircraft in VFR conditions to clear the intended flight
path both before and during climb or descent.

I have always employed S.L.O.P. ever since it came into being. It came in very handy one night when we had to go back to CYYT due to a medical emergancy as it took less time to get to the 15nm offset before turning back. Not only that being two miles over gives you a nice look at who is out there as well.

FoxHunter, what I was trying to convey is that the issue should be promptly addressed by the regulators. Being found to have entered a home made offset after an incident may also pose issues.
