Narrative:

Wingtip vortices. We were cleared for takeoff runway 36R with an MD80 in front of us just breaking ground. I was PIC in left seat and I made a comment to my first officer that they are pushing them out tight tonight. It was a clear night with a 10 KT headwind right down the runway. Around 1000 ft, I felt the first wing wash from the preceding MD80. It dropped my left wing suddenly, and I responded with right rudder and a little aileron. The wings leveled, but then my right wing dropped. I leveled the nose, increased my speed, and made a left turn to avoid another upset. There was no other upset, but the passenger were curious and, I am sure, worried. Lessons learned. No longer will I accept a takeoff clearance that close to another narrow body jet.

Title: MD80 CREW ENCOUNTERED THE WAKE TURB OF THE PRECEDING MD80 AT DFW.

Narrative: WINGTIP VORTICES. WE WERE CLRED FOR TKOF RWY 36R WITH AN MD80 IN FRONT OF US JUST BREAKING GND. I WAS PIC IN L SEAT AND I MADE A COMMENT TO MY FO THAT THEY ARE PUSHING THEM OUT TIGHT TONIGHT. IT WAS A CLR NIGHT WITH A 10 KT HEADWIND RIGHT DOWN THE RWY. AROUND 1000 FT, I FELT THE FIRST WING WASH FROM THE PRECEDING MD80. IT DROPPED MY L WING SUDDENLY, AND I RESPONDED WITH R RUDDER AND A LITTLE AILERON. THE WINGS LEVELED, BUT THEN MY R WING DROPPED. I LEVELED THE NOSE, INCREASED MY SPD, AND MADE A L TURN TO AVOID ANOTHER UPSET. THERE WAS NO OTHER UPSET, BUT THE PAX WERE CURIOUS AND, I AM SURE, WORRIED. LESSONS LEARNED. NO LONGER WILL I ACCEPT A TKOF CLRNC THAT CLOSE TO ANOTHER NARROW BODY JET.
