Narrative:
Cleared for takeoff behind an medium large transport with min spacing. Departure heading was same as preceding aircraft (010 degrees magnetic). About 800 ft AGL, aircraft entered wake turbulence and became difficult to control. I initiated a turn to the left 20 degrees to avoid the wake turbulence and advised ATC. They said unable, to maintain assigned heading. I advised we needed the heading to maintain safety of flight. Controller wanted to argue the point. I turned to the heading I needed to maintain positive control of the aircraft. Atl tower routinely departs commuter size aircraft behind large aircraft with min spacing.

Title: AN LTT GOT INTO WAKE TURB RIGHT AFTER TKOF BEHIND AN MLG AT ATL.
Narrative: CLRED FOR TKOF BEHIND AN MLG WITH MIN SPACING. DEP HDG WAS SAME AS PRECEDING ACFT (010 DEGS MAGNETIC). ABOUT 800 FT AGL, ACFT ENTERED WAKE TURB AND BECAME DIFFICULT TO CTL. I INITIATED A TURN TO THE L 20 DEGS TO AVOID THE WAKE TURB AND ADVISED ATC. THEY SAID UNABLE, TO MAINTAIN ASSIGNED HDG. I ADVISED WE NEEDED THE HDG TO MAINTAIN SAFETY OF FLT. CTLR WANTED TO ARGUE THE POINT. I TURNED TO THE HDG I NEEDED TO MAINTAIN POSITIVE CTL OF THE ACFT. ATL TWR ROUTINELY DEPARTS COMMUTER SIZE ACFT BEHIND LARGE ACFT WITH MIN SPACING.
