RLatSM on NAT Tracks
A bit of help from our ATC colleagues please. I have been reading NATS Ops Bulletin 2015-003 about reduced lateral separation minima in the NAT Tracks and it's implementation in Nov 2015. With the separation being reduced to ˝ degree/25nm on designated tracks, I can't see any change to the contingency procedures to reflect that. It seems as if one should still turn 45 degrees left to right and offset 15nm before descending.
I fly a Gulfstream on random routes usually above the NAT (FL430/450) and was wondering if the contingency procedure, should I have to descend through those designated routes, remains the same and also if operators that are cleared for RLatSM have received any updates should they have to descend.
Any help with a reference would be very useful - I have looked at the 'NORTH ATLANTIC OPERATIONS AND AIRSPACE MANUAL' but that still states as above.
Thanks.

Expect these to remain unchanged Mike.
Have a look at PANS ATM (ICAO Doc4444) 15.2 ‘Contingencies in Oceanic Airspace’ . and 15.2.3 ‘Weather deviation procedures' for the detail.
I believe that a 'Special Emphasis Item' Ops Bullitin will be published shortly that will summarise some items that's intended to compliment the NAT Ops Bulletin you refer to.
If you need more, PM me.

Just an innocent, & genuine, question - might be naive, too ! how does half a degree of latitude equate to 25nm ? Surely half a degree is 30 nam, or have I missed something ?
Half a degree of latitude between tracks only equates to 30nm separation if they are aligned due east-west.
