We were at FL360 RIC-STL yesterday. This guy was 1000' above. I didn't have time to swap to my big lens.

150mm, f/8, ISO 100, 1/800 on a Zuiko lens.

Thanks for the compliments folks. I have never been able to get anything on Airliners.net. Maybe my luck with change with this one.

Does a separation distance that close cause an RA?

Nope, TCAS II software was updated to V.7 fix this sort of thing prior to DRVSM airspace going live.

We have wake turbulence issues fairly often on the north atlantic track system. Oftentimes we'll offset to avoid it when the winds are at a velocity and angle to make it a factor.

Too many stories of sitting there working on a post position plot on Track B, then a 747 silently overtakes you from 1000 above, then WHOMP! Then the sound of crap falling in the forward galley and the A-line's walker rolling down the aisle.
