A380 wake turbulence sends business jet in uncontrolled descent

Wow, I see they're not familiar with the recat wake turbulence chart. A 747 does not need 4 miles behind another heavy anymore. And the special category for 757 is gone.
You would know better than I. I vaguely recall something about the 747 change. However, until just now, I never had any doubt there was still a special for the 757. Since you can rarely see it, my motto with W/T is "assume and avoid". :)
Curious, when and why was the 757 category eliminated/changed? What's its current status?? I'm going to go out on a limb here and guess it's not simply "Don't worry 'bout it, it's just a jet" ;)

Well I guess they did some study and said that it wasn't needed. I don't think there ever was extra wake sep applied to the 757 in Europe. But the 757 is now considered a class D large so the only thing that needs extra spacing is a small (i.e. Citation, PC12, C172) and that's 4 miles. The Recat seperation standards weee adopted here in NY early 2015. A couple places had it (and an earlier, slightly different version) in 2014. I think it's national now but it might not be, so some places may still have to apply the special 757 seperation. That's the FAA for you.
 
When I was in the Q, I dreaded following a 739. It wouldn't roll us but we almost always got a few uppercuts on the way down.
 
This story hit the news in Australia today:

Jet rolled over and plummeted 3000m after being caught in superjumbo’s wake

Those don't look like the same airplane, the windows, side panel, and wood trim are different.

Probably cause the before pic looks like a promotional advertisement stock pic to make the cabin/windows look larger then they are in reality. Kinda like a cruise ship advertisement pic of how BIG and SPACIOUS your shoebox cabin will be!:mad:
