Narrative:

At 1000 ft; navigation mode; hand flown; our aircraft encountered heavy to severe wake turbulence from preceding MD80. It looked like captain used full aileron and possibly rudder throw to try to maintain aircraft control. First a violent left roll; then a right; a couple seconds later it repeated; other direction. This turbulence caused our aircraft to deviate from RNAV departure centerline. Captain was attempting to return to centerline. I advised departure of this problem. At 2000 ft turbulence ended. Controller asked if we could continue with RNAV departure. I said we could and were returning to course. Controller stated no traffic separation occurred.

Title: MD80 FLT CREW ENCOUNTERS HEAVY TO SEVERE WAKE TURB DURING DEP FROM DFW.

Narrative: AT 1000 FT; NAV MODE; HAND FLOWN; OUR ACFT ENCOUNTERED HEAVY TO SEVERE WAKE TURB FROM PRECEDING MD80. IT LOOKED LIKE CAPT USED FULL AILERON AND POSSIBLY RUDDER THROW TO TRY TO MAINTAIN ACFT CTL. FIRST A VIOLENT L ROLL; THEN A R; A COUPLE SECONDS LATER IT REPEATED; OTHER DIRECTION. THIS TURB CAUSED OUR ACFT TO DEVIATE FROM RNAV DEP CTRLINE. CAPT WAS ATTEMPTING TO RETURN TO CTRLINE. I ADVISED DEP OF THIS PROB. AT 2000 FT TURB ENDED. CTLR ASKED IF WE COULD CONTINUE WITH RNAV DEP. I SAID WE COULD AND WERE RETURNING TO COURSE. CTLR STATED NO TFC SEPARATION OCCURRED.
