NAT Doc 007 is the Bible of the North Atlantic. It’s full of NAT goodness – all the specifics about how to operate your aircraft safely through the complex airspace of the region is here.
And there’s another new edition!
The NAT changes over the last few years have been coming thicker and faster than the sandwiches at Katz’s Deli on the Lower East Side. And now, there’s more. Effective August 7th, 2019, NAT Doc 007, Version 3, is the latest tome to digest. As aviation documents go, it’s written in pretty digestible language. There’s just a lot in it. But this is the first time we’ve had 3 editions of this in one year.
So, we’re going to start naming them after 007 Movies to keep track of them all. This is the “Two is Not Enough” edition.

So, here are the three things that have changed this time:
1. We got new SLOP rules! This is a biggie. Instead of the three previous choices (0, 1, or 2nm), we now have Twenty One choices! More on this below.
2. 99 problems and Datalink is one. The short version: check that you’ve got the latest software update for your datalink.
3. The next datalink mandate (2C) is capped at FL410. This comes in January 30th next year. And so, the Checklist for Dispatchers is updated.
The new SLOP rules
Now, let’s take a closer look at the big change – SLOP (Strategic Lateral Offset Procedure). To get up to speed, check out our full article on SLOP – the how, and why (and where).
The change here is that instead of just being able to SLOP 1 or 2 nm right of track, (or fly the centreline), you go from these three choices to twenty one – you can use any one of 21 Micro-SLOP offsets. Specifically: 0.0 nm, 0.1 nm, 0.2 nm …. OK, you get it. All the way up to 2.0 nm Right of track.
Not quite. It’s not yet fully clear which of the OCA’s have given the green light for this, even though NAT Doc 007 now says you should Micro-SLOP if you can.
But, phoning around the Oceanic Houses, we’ve got this to tell you:
1. Gander – you can micro-SLOP right now! An AIP amendment will follow soon.
2. Shanwick – you can micro-SLOP right now! A Notam will be published soon, and the AIP will be updated in Dec 2019.
3. New York – they will allow micro-SLOP from 12th Sept 2019, and will update the AIP in Jan 2020.
4. Santa Maria – you can micro-SLOP right now! Nothing published officially yet, but that’s what the good people from the oceanic control centre have told us.
5. Iceland – just like New York, they will allow micro-SLOP here from 12th Sept 2019 as well. When that happens, you will still not be allowed to SLOP below FL285 within the Reykjavik CTA (that’s the domestic part over Iceland, and the airspace over Greenland above FL195). We asked them to publish a Notam about this – and they actually did!! Check it out!
6. Bodo – Nothing official yet, but ATC say they “have no objections” to operators micro-SLOPing right now. (Currently, SLOP is only allowed here above FL285 within the OCA.)
That’s the current picture as of 1100z on Monday 19th Aug.
We will update this as soon as we get more info. Got something for us? Email us!
