Its mostly anything and even similar sized aircraft can give you a ride.<br /><br />RVSM has us at 1000' vertical seperation. Vortices trail and descend behind the aircraft, so being behind and slightly lower is the problem area. We are allowed to offset laterally in oceanic airspace up to 2 miles right. Of course that doesnt help anything if everybody is 2 miles right of course. If I can see the passing aircraft I will generally try to offset laterally for a little while until it is farther ahed to miss the votices.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-7996300700881181372017-03-20T20:29:30.317-05:002017-03-20T20:29:30.317-05:00Given that the wake turbulence was enough to total...Given that the wake turbulence was enough to total out an aircraft and send the passengers and crew to the hospital, one with serious injuries, I'd advocate grounding all airbus size aircraft until a fix can be found.

I realize they are trying to squeeze more traffic into the transatlantic lanes, but it's simply dangerous. I went through wake turbulence coming out of Atlanta a few years back and it wasn't fun.

WAAS is about the ONLY fix, other than wider spacing horizontally between acft, or some degradation model of wake turbulence (both vertical and horizontal dispersion) that attaches to the acft bug for the controllers.

The controls are linked by steel (or carbon fibre/kevlar) cables to hydraulic PCUs (Power Control Units) at each control surface. The cables only move a valve, (2 valves in the case of the aileron PCU) to port hydraulic fluid to one side or the other of the PCU piston. Without hydraulic pressure there is no possibility of control. Fortunately even with both engines flamed out they will windmill at about 17% in a glide giving a bare minimum of flow on the engine driven pumps. <br /><br />They were really lucky that the 604 didn't pitch up into a deep stall from which there is no recovery. I would love to hear the CVR tape from this incident. I would guess the pilots were well trained.<br /><br />Regarding the EASA report, for the past 20 years the industry has been trying to squeeze airplanes together tighter via RVSM (Reduced Vertical Separation Minimum) and WAAS (Wide Area Augmentation System) which basically creates three electronic lanes in the sky, 10 miles apart. <br /><br />Al_in_Ottawa Anonymousnoreply@blogger.com
