Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Regained Aircraft Control
Environment - Non Weather Related; Procedure
While operating to CLT; we encountered wake turbulence. We were talking to CLT final approach control who gave us a 330 heading to intercept the localizer for runway 36L. We were level at 4000 feet and assigned 170 knots. We were not issued any information about traffic in front of us; although we did see a target about 3 miles ahead of us on the TCAS. Shortly before localizer intercept; we encountered severe wake turbulence that rolled the airplane approximately 40 degrees and disconnected the autopilot. I assumed manual control; turned on continuous ignition and hand flew the rest of the approach 1/2 dot above the glideslope to avoid further wake. We queried ATC and were told we were following an A321. This is not the first time I've encountered wake here in CLT. Controllers seem to not respect the effect of wake on our airplanes.
CRJ-900 Captain reported encountering wake turbulence on approach to CLT in trail of an A321 that rolled the aircraft 40 degrees.
