Inflight Event / Encounter Wake Vortex Encounter
Air Traffic Control Issued New Clearance; Flight Crew Requested ATC Assistance / Clarification
Environment - Non Weather Related; Procedure
While on the descent into ORD on the WYNDE 8 arrival; we encountered wake turbulence between PAITN and WYNDE fix. While on autopilot the aircraft rolled to the left then to the right. I disconnected the autopilot and assumed manual control. The aircraft rolled again left and then right. I called for 'ignition continuous' then; I asked the Captain 'what we were following?' He questioned ATC; ATC replied 'an Airbus A330.' The Captain told ATC that we encountered wake turbulence. At that time the Captain and I noticed the separation between the Airbus and our aircraft was less than ten miles. ATC then gave us vectors [and] while on that vector we encountered additional wake turbulence. Once we were out of the wake turbulence; the Captain called the flight attendants to ask if [everyone] was okay; and they said no one was injured. The flight attendants did make an announcement regarding this situation after speaking with the Captain. We continued the approach and landed safely with no further issues.
CRJ-900 First Officer reported encountering wake turbulence on descent into ORD in trail of an A330.
