MD-11
Flight Crew Air Transport Pilot (ATP)
Deviation - Speed All Types; Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
Momentary stick shaker occurred on departure. We were heavy; 612k; and used max power to obtain a stop margin of 190 FT. Our takeoff sequence put us in trail of a heavy B-777 by about 5 miles. Shortly after takeoff; we encountered wake turbulence that rolled the aircraft right and left about 15 degrees; but was manageable. After accelerating; and cleaning up on schedule; with clean configuration; well above [slat retraction] speed; but not yet to [clean maneuvering speed]; we encountered wake turbulence again; this time a bit more severe; the aircraft rolling right to a bank of about 25 degrees. As advertised; when passing the bank limiter; stick shaker occurred momentarily. I unloaded the aircraft slightly; continued to accelerate; and rolled the aircraft back to level flight. The remainder of the flight was uneventful. Cause: Departure Control sequenced us too close in trail to previous heavy jet departure.
