MLG ACFT WENT OFF END OF RWY 24R AT LAX.

Narrative

ILS APCH TO LAX 24R WAS NORMAL IN EVERY RESPECT. APCH LIGHTS IN SIGHT THROUGHOUT APCH. LANDED IN TOUCHDOWN ZONE IN SHALLOW FOG. VISIBILITY DETERIORATED RAPIDLY IN PATCHY GND FOG. DIDN'T SEE HIGH SPD TURNOFF UNTIL TOO LATE TO EXIT SMOOTHLY. TWR SAID 'ROLL TO THE END AND TURN L.' TAXI TO END WAS NORMAL. OBSERVED 3000 FT ALTERNATING RED AND WHITE LIGHTS; THEN 1000 FT OF RED CENTERLINE LIGHTS. AS BRAKES APPLIED TO EXIT RWY; ANTI-SKID SYS GAVE RAPID RELEASES IN THRESHOLD PAINTED AREA AT END OF 24R. ACFT PROCEEDED STRAIGHT AHEAD AND DEPARTED RWY. NO OVERRUN IS PROVIDED ON LAX 24R. VISIBILITY WAS ALMOST 0 IN FOG. UPON DEPLANING; FO AND I WALKED OVER TO THRESHOLD AREA AND OBSERVED EXTREMELY SLICK PAINTED SURFACE. LAX NEEDS TO USE MORE ABRASIVE PAINT IN THRESHOLD AREA. LAX NEEDS TO PROVIDE SOME OVERRUN AREA BEYOND END 24R. SUPPLEMENTAL INFO FROM ACN 195641: LNDG WAS MADE ON SPD; AND SLIGHTLY PAST TOUCHDOWN ZONE LIGHTING. PLANNED TO EXIT AT SECOND HIGH SPD TURNOFF; BUT LEAD-IN LIGHTING TO HIGH SPD COULD NOT BE SEEN UNTIL DIRECTLY ABEAM THE HIGH SPD. TWR ASKED US TO 'ROLL TO THE END AND TURN L.' CAPT CONTINUED TAXI TO THE END AND CALLED OUT '3000 FT AND 1000 FT REMAINING' AS WE PASSED THE RESPECTIVE POINTS. VISIBILITY WAS VERY POOR IN PATCHY; DENSE GND FOG BEYOND THE TOUCHDOWN ZONE. AS THE CAPT APPLIED BRAKES TO MAKE THE L TURN; BRAKING ACTION WAS NIL. ANTI-SKID CYCLED RAPIDLY AND CONTINUOUSLY UNTIL THE ACFT STOPPED. WE ADVISED TWR AND PAX WE WERE OFF THE END OF 24R. EVALUATED AND SAW NO REASON FOR EVACUATION. UPON DEPLANING; I WALKED TO THE PAINTED THRESHOLD MARKINGS AND OBSERVED EXTREMELY SLIPPERY; APPARENTLY FRESH PAINT.
