Expansion of NAT Reduced Lateral Separation Delayed
The initial phase of the reduced lateral separation minimums from 50 nm to 25 nm in the North Atlantic Tracks was introduced in December last year.

Phase two of the reduced lateral separation minimums (RLatSM) expansion plan in the North Atlantic Tracks (NATs) was to start on Thursday, but that plan is delayed, probably to next year. The initial phase of RLatSM from 50 nm to 25 nm in the NAT system was introduced in December last year. Since then, there has been the option for appropriately equipped aircraft to use one of the three new RLatSM routes.
