"A380 set for cut in wake separation, Research will probably prove closer approaches possible"
Quote: Airbus A380 wake turbulence in-trail separation criteria may be reduced later this year from the distances published in the safety case study late in 2006, it emerged at Eurocontrol's international WakeNet conference in Brussels, Belgium last week. Meanwhile, existing separation standards between in-service aircraft are to be reviewed.
The 180 flying-hour A380 wake vortex behaviour flight- test programme, monitored by the European Joint Aviation Authorities, the US Federal Aviation Administration and Eurocontrol, ensured that the aircraft will enter commercial service with a scientifically determined wake separation classification known as "super-heavy". FAA wake turbulence programme manager Steve Lang says it was the first time such tests had been done, but that all new aircraft will go through a similar process from now on....
IIRC, there hasn't been much news concerning this topic since last fall, although there isn't much in the way of specfics in the article, there is some interesting news about a similar process being adopted for future aircraft.
