A319 Captain reported encountering wake turbulence from a preceding B787 on approach to ORD.
Synopsis
A319 Captain reported encountering wake turbulence from a preceding B787 on approach to ORD.
Narrative
We were cleared to descend to 4000 ft. on the WYNDE2 Arrival. Ahead of our flight was a B787 that was cleared to 5000 ft. I queried Approach Control to bring awareness to the fact that we were approximately 10 miles behind the aircraft. However; the winds were 110 at 25 gusting to 30 at 400 ft.The winds were pushing the vortices in the direction of our flight and creating turbulence with rolls of approximately 10 - 20 degrees and pitch deviations of 2 degrees.The Approach Controller responded to my request to work out a different solution with the following response; 'There is no other plan; you are staying behind the heavy... somebody has to follow them.'My FO developed our own escape plan just in case the turbulence got worse.We were ultimately placed behind an Airbus A350 that was also at 5000 ft. and approximately five- and one-half miles ahead of us.The landing was made successfully with no injuries or damage.Advise ORD Approach that in trail heavies should NOT be placed above non-heavy aircraft.
NASA callback
Reporter stated the encounter probably could have been avoided or minimized if ATC had taken more care with altitude assignments of the preceding heavy aircraft.
