Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
Description===========Type Incident:  Aircraft UpsetWe were descending to DFW.  As we flew through about 8500ft. and about 10nm below and behind an A-380 Super Jumbo; we encountered strong wake turbulence.The aircraft started a fast and aggressive roll to 30 degrees right bank.  The autopilot disconnected and I told the First Officer (FO) who was Pilot Flying (PF) to 'Grab It!'  He immediately started a wings-leveling correction effort; and fought to maintain it and started a climb.  I directed him to turn right in the direction of the upwind side.As we climbed and turned upwind we exited the wake turbulence area.  I'm uncertain exactly how much we deviated in altitude and heading and speed during the event.  But I'm certain it wasn't too excessive and we returned to our cleared descent to 5;000 feet as soon as we could.  We were both alert and prepared in advance for the possible wake encounter.  This helped us to react quickly and decisively to correct the upset event.  ATC was notified of the event and I recommended a minimum of 20nm in flight separation for following an aircraft of that size. The controller indicated he would pass it on to the previous controller that had maneuvered us within 10nm of the A-380 with previously assigned vectoring.  Our subsequent descent and landing to RWY 13R was uneventful.SuggestionsAs noted above; I recommended strongly to ATC that they provide an absolute minimum of 20nm in-flight separation for narrow body aircraft when following a Super Jumbo sized aircraft like an A-380.I hope they took my suggestion very seriously.  I'll know they did if they change their vectoring procedures in the future to provide my recommended minimum separation suggestion.  I would hope they follow up with me about their future intentions in that regard...
B737-800 Captain reported encountering wake turbulence in trail of an A380 on approach to DFW. Reporter recommended in-trail separation of smaller transport aircraft behind Super Jumbo aircraft be raised to 20 miles.
