Flight Crew Air Transport Pilot (ATP)
Inflight Event / Encounter Wake Vortex Encounter
Air Traffic Control Issued New Clearance
Environment - Non Weather Related; Procedure
Eleven miles in trail behind an A380; co-altitude (11;000 feet); encountered its (surprisingly violent) wake turbulence. ATC was immediately informed of situation and that we were slowing from our assigned '300 Knots or greater' to 275 knots. ATC vectored us off the Boove1 and changed our assigned runway. I was surprised; as we are taught that wake turbulence spreads and descends. I was flying; the Captain did a very good job and was keeping an eye on the A380 even before this.On the ground I asked the Flight Attendant if she or the PAX had any issues with it; she said no; but it got her attention.Research incident; verify/correct existing Wake Turbulence data. Recommend increasing spacing behind Super-heavy aircraft.
Reporter stated they were above the A380 (since it had started its descent); 11 miles in trail; and still got 'rocked really good.'
