Narrative

ATC FACILITY: SOCAL APCH. LOCATION: LAX LOC 109.9/ 9 NM. APCH RWY 25R LAX. FOLLOWING L1011. APPROX 9 MI AND 5 MI BEHIND; WE ENCOUNTERED WAKE VORTEX STRONG ENOUGH TO REQUIRE SIGNIFICANT AILERON THEN LOTS OF RUDDER TO KEEP OUR ACFT UNDER CTL. WE WERE ALREADY 2 DOTS HIGH BECAUSE OF PREVIOUS NIBBLES ON THE GS AT 1 DOT HIGH. SANTA ANA TAILWIND CONDITIONS WERE PRESENT. LAX WIND AT 060 DEGS/9 KTS. VMC. CONTINUED APCH. NO FURTHER INCIDENTS TO RPT. I MUST SAY THIS INCIDENT DID SCARE ME A BIT. I AM THANKFUL FOR THE COMPANY TRAINING AS WELL AS RECURRENT UNUSUAL ATTITUDE TRAINING. THE RUDDERS WORKED GREAT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT HE FELT 'NIBBLES' OF THE WAKE PROB WHEN 52 MI OUT SO HE MOVED UP FROM 1 DOT TO 2 DOTS ABOVE GS. HE WAS QUITE SURPRISED WHEN THIS WAS NOT ENOUGH. HE FEELS THE TAILWIND CONDITION CONTRIBUTED TO THE WAKE REMAINING FOR SO LONG BEHIND THE L1011. THE ACFT WAS BACK UNDER CTL IN ABOUT 3-5 SECONDS. HE FEELS THERE SHOULD BE GREATER IN TRAIL SEPARATION WHEN TAILWIND CONDITIONS EXIST.
