Environment - Non Weather Related; Procedure
During radar vectors to final approach ILS 17L MCO base leg encountered severe wake turbulence. Aircraft on a 90 degree base leg; assigned speed 210 KIAS; descending 4000 to 3000 ft; aircraft suddenly rocked side to side disengaging autopilot. I immediately determined we were going to overshoot localizer because [of the] angle to localizer. I am hand flying at this point trying to get aircraft back on localizer and not bust altitude. Controller noticed our difficulty and asked if we would want to do a 360 and try again. I told FO (First Officer) to report the wake turbulence to controller which he did. No traffic in our vicinity at the time of occurrence.Too close to traffic ahead of us on same flight path. ATC should not be assigning a speed of 210 KIAS on a 90 degree angle to localizer when less than 2 miles from intercept.
On a short vector; 90 degrees to final approach course received a 210 degree heading to intercept final approach course on 17L at MCO. Upon starting turn; we hit significant wake turbulence that forced the auto pilot to disconnect and revert to CWS (Control Wheel Steering) in pitch and roll. PF (pilot flying) disconnected auto pilot and began course correction and as we started our turn we overshot final. Advised ATC of the issue and were vectored to approximately a 090 degree heading to circle back around and resume approach. No apparent conflict with other traffic was observed.We were advised by ATC to keep speed up during approach so we were in a steeper and faster and closer to final approach than normal. This compounded the course intercept when the auto pilot disconnected due to the wake turbulence. Due to the phase when the disconnect happened; quick corrective action was needed to avoid further overshoot.This was perceived to be a somewhat normal approach on a VMC day that was compounded by automation problems upon hitting wake turbulence. No suggestion for improvements at this time.
B737-800 flight crew reported breaking off the approach to MCO when a wake turbulence encounter contributed to a track deviation during localizer intercept.
