Way Point IBROD ( 56 degrees 30 minutes north, 10 degrees west )

[Albaman]

I recently had a sight of an Atlantic Transition chart ( albeit probably not the most recent edition ) and noticed the above Way Point. I was under the impression that in the North Atlantic track sysytem, the lateral separation is 60 nautical miles. As a result, I was wondering if and when traffic is routed via IBROD.

Any information would be much appreciated.

IBROD is still in use. See Upper Air Routes (http://www.ead.eurocontrol.int/eadbasic/pamslight-B75498E8E390851F18BB4C3CC467C09B/7FE5QZZF3FXUS/EN/Charts/ENR/AIRAC/EG_ENR_6_3_2_2_en_2011-09-22.pdf)

It is the boundary of the UK FIR with the Northern Oceanic Transition Area (NOTA). Aircraft may flight plan to use IBROD typically when on UM132. See for example VIR71 (http://flightaware.com/live/flight/VIR71/history/20110924/1105Z/EGPF/KMCO)
Full 60nm separation is achieved at 15W

Thanks for your prompt reply.

[10W]

There is also KUGUR, at 5530N 10W, between NIBOG and MIMKU. It's mostly used on Eastbound night time fuel saving routes, albeit not commonly.
