Environment - Non Weather Related; Procedure
While descending on the WESAT2 arrival into FTW; we encountered wake turbulence from a Boeing 767 that was approximately 20 miles in front of us and traveling in the same direction. Our aircraft banked to the left approximately 45 degrees and our autopilot disconnected. At this point I took over the controls and righted the aircraft while still fighting more of the turbulence. After a few seconds we were offered an offset from Fort Worth Center of which we accepted and made a right turn to put us more upwind. Soon after we were cleared direct to COWTN near FTW and we exited the event.
G280 Captain reported encountering wake turbulence on descent into FTW 20 miles in trail of a B767 that resulted in an uncommanded 45 degree roll to the left.
