Feb 6, 2020 at 16:19 comment added reirab @MSalters That's often true. But they're also just not active at the same times of day. At any rate, my point was just that RSVM sometimes does mean 1,000' separation for same-direction traffic.
Feb 6, 2020 at 12:01 comment added MSalters @reirab: Isn't that because the North Atlantic Tracks have many miles of lateral separation, if not entire degrees, between the east- and westbound tracks? IIRC this is not for safety reasons, but because the tracks are chosen with regard to prevailing winds.
Feb 5, 2020 at 16:28 comment added reirab @ymb1 Though there are exceptions, such as the North Atlantic Tracks, where it's 1,000' same direction (because nearly all of the traffic is going the same direction at a given time of day.)
Feb 5, 2020 at 8:55 comment added user14897 @DeepSpace: 2,000 ft is RVSM; same travel direction, e.g. → 310 ← 320 → 330 ;-)
