Environment - Non Weather Related; Procedure
As we descended through 11;000 feet via the SEEVR4 arrival past the BRDJE checkpoint slowing to 240 KIAS and approaching the NUSSS checkpoint the aircraft unexpectedly rolled 30 degrees right with moderate turbulence. The FO (First Officer) immediately disengaged the autopilot to right the aircraft. The CA (Captain) immediately reported the wake turbulence to Fort Worth approach requesting a 2 mile offset to the left which was upwind of the wake. ATC gave us an immediate vector to 165 degrees and descended us to 6;000 feet. When the aircraft was stable the autopilot was reengaged. ATC indicated we were following a B787. The CA called the FAs to check on crew and passengers - all were fine. ATC vectored us to the ILS 17C approach course right behind the same B787 that caused us the problem earlier. We were aware of the situation and commenced the approach. All went well until we started to get light turbulence near the PENNY checkpoint. The FO remained high on the glide-slope but at a half dot high and going higher the CA requested the FO descent not to exceed 1500 FPM.All checklists were complied with; handoffs to Tower; and cleared to land. The FO complied and clicked off the autopilot to hand fly the approach as the runway was in sight and the FO was visual. Crossing the final approach fix at Jiffy and stable by 1;000 feet AFE the turbulence started up again and a noticeable downdraft occurred whereby the aircraft was momentarily at 1;000 FPM as the FO added power. The CA called one dot low at 750 feet (happened fast). No windshear caution or alert. The FO was quick to get back on glideslope; but left the power in so immediately found us a bit high on the approach by 1 dot. As the FO brought the thrust levers to flight idle at 150 feet the CA called the go-around. ATC was immediately notified of the missed approach and all checklists and call outs were complied with according to the flight manual and company procedures. ATC vectored us for the ILS 17L approach whereby a successful approach and landing was made. The Company was notified as well as the Regional Chief Pilot.Preventative Actions: ATC should be cognizant of the wind direction when wind parallels the arrival corridor. Wake turbulence remains along the course lines of arrival and lingers longer than when winds are perpendicular to the arrival course lines. Recommend a larger spacing between heavy aircraft and medium aircraft categories.
