Narrative:

Atl approach descended us down to 3000 ft from 3500 ft MSL to try to pick up preceding traffic visually, to probably close up spacing (from 5 NM). With winds on the nose at 11 KTS, this put us in the MD11's wake turbulence. First encounter required disengagement of autoplt. Reported same to ATC. Encountered more wake turbulence requiring aileron input to overcome uncommanded rolls 2-3 more times. Plane was also jostled, prompting comments from 1-2 passenger and flight attendants. Atl's cavalier attitude about wake turbulence, to cram as many arrs into atl as they can, will result in an incident, if not an accident, as traffic increases.

Title: A B757 CAPT RPTED THAT A80 VECTORED HIM TOO CLOSE IN TRAIL BEHIND AN MD11, CAUSING HIM TO ENCOUNTER WAKE TURB ON THE APCH TO ATL.

Narrative: ATL APCH DSNDED US DOWN TO 3000 FT FROM 3500 FT MSL TO TRY TO PICK UP PRECEDING TFC VISUALLY, TO PROBABLY CLOSE UP SPACING (FROM 5 NM). WITH WINDS ON THE NOSE AT 11 KTS, THIS PUT US IN THE MD11'S WAKE TURB. FIRST ENCOUNTER REQUIRED DISENGAGEMENT OF AUTOPLT. RPTED SAME TO ATC. ENCOUNTERED MORE WAKE TURB REQUIRING AILERON INPUT TO OVERCOME UNCOMMANDED ROLLS 2-3 MORE TIMES. PLANE WAS ALSO JOSTLED, PROMPTING COMMENTS FROM 1-2 PAX AND FLT ATTENDANTS. ATL'S CAVALIER ATTITUDE ABOUT WAKE TURB, TO CRAM AS MANY ARRS INTO ATL AS THEY CAN, WILL RESULT IN AN INCIDENT, IF NOT AN ACCIDENT, AS TFC INCREASES.
