Environment - Non Weather Related; Weather
Before turning left base for RWY 36L at 4;000 feet; we noticed we were following a larger aircraft. I noticed on my range scale the preceding aircraft was more than 5 miles ahead. We were heading south on the arrival. Approach turned us left heading 090. We were still slightly more than 5 miles in trail. Approximately half way through the left turn the aircraft rolled further left to approximately 50 degrees; resulting in the AP disconnecting and the 'Bank Angle Aural'. I assumed manual control and initially leveled the wings; maintained our altitude and resumed the turn manually. Once level on the 090 heading i asked for the AP to be turned back on and we let ATC know we just encountered wake turbulence. They let us know we were 5 miles in trail of an A321. The rest of the flight continued with no further event.
CRJ pilot reported they were surprised at the strength of the wake from a narrow body aircraft.
Captain of medium transport aircraft reported encountering wake turbulence on arrival into CLT in trail of an A321.
