Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
Upon being cleared to line up and wait on Runway 24L at LAX; the Captain and I started a clock to note the time of takeoff roll for a B777 departing just prior to us. When we were cleared for takeoff; we verified a full two minutes had elapsed. The Captain said he would plan to lift off prior to and climb above any remaining wake left by the B777. Winds were light from the southeast and noted. The Captain verified that I agreed we were safe to depart (given the B777 ahead). We took off without incident. Climbing out of approximately 1;800 FT MSL; we suddenly entered remaining wake (assumed from the B777). Nearly full control inputs were required from the Captain to maintain relatively level flight and to reduce our climb rate in order to fly out of the wake. The turbulence lasted approximately ten to fifteen seconds. ATC was notified. The plane and passengers only felt a moderate type of turbulence. While all common sense and procedural items were complied with; perhaps an ATC or pilot requested early turnout after liftoff (to avoid trailing the heavy B777) would be appropriate. I certainly don't intend to allow my aircraft to be in any potential wake path again.
B737-300 First Officer reported encountering wake turbulence from preceding B777 on departure from LAX.
