Challenger 350
Flight Crew Air Transport Pilot (ATP)
Inflight Event / Encounter Wake Vortex Encounter; Inflight Event / Encounter Loss Of Aircraft Control
Flight Crew Regained Aircraft Control; Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
On the ANJLL arrival; Runway 25L Transition; approximately between CRCUS and KRAIN (could be further east on the arrival); [we] encountered significant wake turbulence from an A380 12.5 nm ahead and 2300 feet below. This is an area where orographic turbulence is usually encountered; but there was no mistaking being caught in the wake of the A380. It wasn't wake 'turbulence'; it was a wake 'took control of the aircraft' event. Autopilot was on; speed was assigned; I think at 250 knots. We were exactly where we were supposed to at the assigned speed. [We] pitched up; rolled right significantly; leveled and then rolled left. I disconnected the autopilot; pulled up and banked left to get into the clean air; which I pre-determined earlier when advised we were following an A380 due to the earlier slight left wind from about 11 o'clock at 7 knots. There may have been other pitch and roll excursions as I exited into clean air. [We were] completely at the mercy of the A380's wake; until clear. The FO advised approach of the encounter. I also advised him to advise approach that we were offsetting .2 NM; I think; to the left. We quickly set an offset into the flight plan and continued. Approach advised that the A380 was now proceeding to the Runway 24s or 'north complex'; which further diverged our paths. We asked the passengers if they were ok and they also asked if we were ok. Everyone was fine. Nothing came apart or out of its carriage. No damage.During oceanic operations we use SLOP (Strategic Lateral Offset Procedure). I now firmly believe that we must use a SLOP procedure when following a much larger aircraft. Advise ATC that we are SLOPing into the direction of the clean air. Also; it seems INSANE to be at the same arrival altitudes the massive aircraft was just at. We should always use the top most altitude on all arrivals and in this case; request a 1000 or 2000 ft separation on the arrival or a COMPLETELY DIFFERENT ARRIVAL and APPROACH.
CL-350 Captain reported encountering significant wake turbulence on approach to LAX 12 miles in trail of an A380 that resulted in a momentary loss of control of the aircraft.
