A321
Flight Crew Air Transport Pilot (ATP)
ATC Issue All Types; Deviation - Track / Heading All Types; Deviation / Discrepancy - Procedural Clearance; Inflight Event / Encounter Wake Vortex Encounter
Air Traffic Control Issued New Clearance
Environment - Non Weather Related; Procedure
On a vector for approach to Runway 23; both Runway 23 and B757 traffic 3nm ahead in sight; CLT Approach Control cleared us for the Visual Approach Runway 23. Upon intercepting the final approach course; we encountered wake turbulence from the preceding B757; which contributed to us going through the final approach course. As we turned back to re-intercept the final approach course; re-encountered wake turbulence which then contributed to us going through the final approach course again. CLT Approach Control intervened and vectored us off the approach to re-enter to an uneventful approach and landing on Runway 23. I suspect the event occurred because we were within the range of the B757 wake. I suggest further separation from traffic ahead.
[Report narrative contained no additional information.]
A321 flight crew reported two track deviations from cleared course when wake turbulence from a preceding B757 was encountered during approach to CLT.
