Narrative:

ATIS: 260/04 10/skc 16/3 30.07. Reduced takeoff power. We were cleared for takeoff on runway 26L immediately behind an A320 and given a heading of 290 or 295 degrees. Shortly after rotating; maybe 100 ft AGL; we encountered wake turbulence; plane rolled left and simultaneously the stick shaker and warblers went off for about 1-2 seconds. I countered with right aileron and held the pitch attitude as the speed nearly dropped below V2+10 KTS. I believe that I used a normal rate of rotation to a normal pitch attitude which would give me V2+10-20 KTS. The winds were very light and aligned with the runway so I feel that it was definitely wake turbulence from the preceding airbus which caused the event. We had selected continuous ignition on prior to takeoff as I have experienced some pretty strong wake turbulence behind an A320 in cruise before; several years ago. The rest of the flight was without further incidents. The handling of the plane never felt abnormal and I did not find anything unusual on the post flight inspection.

Title: CRJ200 FLT CREW REPORTS ENCOUNTER WITH WAKE TURBULENCE FROM PRECEDING A320 SHORTLY AFTER TKOF AT 100 FT AGL.

Narrative: ATIS: 260/04 10/SKC 16/3 30.07. REDUCED TAKEOFF POWER. WE WERE CLEARED FOR TAKEOFF ON RUNWAY 26L IMMEDIATELY BEHIND AN A320 AND GIVEN A HEADING OF 290 OR 295 DEGS. SHORTLY AFTER ROTATING; MAYBE 100 FT AGL; WE ENCOUNTERED WAKE TURBULENCE; PLANE ROLLED LEFT AND SIMULTANEOUSLY THE STICK SHAKER AND WARBLERS WENT OFF FOR ABOUT 1-2 SECONDS. I COUNTERED WITH RIGHT AILERON AND HELD THE PITCH ATTITUDE AS THE SPEED NEARLY DROPPED BELOW V2+10 KTS. I BELIEVE THAT I USED A NORMAL RATE OF ROTATION TO A NORMAL PITCH ATTITUDE WHICH WOULD GIVE ME V2+10-20 KTS. THE WINDS WERE VERY LIGHT AND ALIGNED WITH THE RUNWAY SO I FEEL THAT IT WAS DEFINITELY WAKE TURBULENCE FROM THE PRECEDING AIRBUS WHICH CAUSED THE EVENT. WE HAD SELECTED CONTINUOUS IGNITION ON PRIOR TO TAKEOFF AS I HAVE EXPERIENCED SOME PRETTY STRONG WAKE TURBULENCE BEHIND AN A320 IN CRUISE BEFORE; SEVERAL YEARS AGO. THE REST OF THE FLIGHT WAS WITHOUT FURTHER INCIDENTS. THE HANDLING OF THE PLANE NEVER FELT ABNORMAL AND I DID NOT FIND ANYTHING UNUSUAL ON THE POST FLIGHT INSPECTION.
