B757-200
Flight Crew Air Transport Pilot (ATP)
Deviation - Track / Heading All Types; Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Environment - Non Weather Related; Procedure
[We were a] sequenced departure from Runway 18R in trail of previous departing aircraft. Cleared for OLMES2 RNAV to EMIIT; FMS loaded; LNAV armed. Normal rotation; liftoff and climb; at 1;000 FT VNAV engaged and autopilot on; tracking normally toward EMIIT. Passing 1;500 FT the aircraft rolls left; about 15 degrees of bank; with a slight yaw. Not normal; so I disconnect the autopilot and try to correct right with normal aileron. No response. Applied almost full right aileron to break out of what I believe to be a wake turbulence encounter from the previously departed aircraft. Corrected back on course with no further turbulence encountered. Wind 180/4 at takeoff. [We] notified Tower and Departure Control of event; Tower as it was occurring and Departure a few moments later. Suspect light tailwind may have created the environment for this to occur. Providing this information as data to evaluate RECAT under these conditions. I have never experienced this type of situation before and consider myself a fan of RECAT.
[Report narrative contained no additional information].
B757-200 flight crew reported encountering wake turbulence shortly after takeoff in trail of another aircraft.
