On initial contact with socal; they did not assign a runway for the SEAVU1 arrival. Second controller initially issued runway 24R; then immediately said 'no; let's change that to 25L.' we acknowledged and continued descent in moderate turbulence and light to moderate precipitation. Final socal controller cleared us for the ILS approach runway 24R at palac. We responded that we were flying the runway 25L ILS (or would when we intercepted at termination of the seavu arrival). He said ok; no problem; turn right 10 degrees and intercept the runway 24R localizer and cleared for the ILS runway 24R approach. We completed the approach and landing to runway 24R without further incident. Socal makes runway assignments and RNAV arrival assignments very late sometimes and makes changes right on top of the initial fixes. This time in poor WX and turbulence; it makes the crew's job quite difficult and still be heads-up in the cockpit for other issues.
Original NASA ASRS Text
Title: A B757 PILOT REPORTS AN APCH CHANGE MADE LATE IN SEAVU 1 ARRIVAL FROM LAX RWY 25L TO 24R IN TURB AND RAIN.
Narrative: ON INITIAL CONTACT WITH SOCAL; THEY DID NOT ASSIGN A RWY FOR THE SEAVU1 ARR. SECOND CTLR INITIALLY ISSUED RWY 24R; THEN IMMEDIATELY SAID 'NO; LET'S CHANGE THAT TO 25L.' WE ACKNOWLEDGED AND CONTINUED DSCNT IN MODERATE TURB AND LIGHT TO MODERATE PRECIPITATION. FINAL SOCAL CTLR CLRED US FOR THE ILS APCH RWY 24R AT PALAC. WE RESPONDED THAT WE WERE FLYING THE RWY 25L ILS (OR WOULD WHEN WE INTERCEPTED AT TERMINATION OF THE SEAVU ARR). HE SAID OK; NO PROB; TURN R 10 DEGS AND INTERCEPT THE RWY 24R LOC AND CLRED FOR THE ILS RWY 24R APCH. WE COMPLETED THE APCH AND LNDG TO RWY 24R WITHOUT FURTHER INCIDENT. SOCAL MAKES RWY ASSIGNMENTS AND RNAV ARR ASSIGNMENTS VERY LATE SOMETIMES AND MAKES CHANGES RIGHT ON TOP OF THE INITIAL FIXES. THIS TIME IN POOR WX AND TURB; IT MAKES THE CREW'S JOB QUITE DIFFICULT AND STILL BE HEADS-UP IN THE COCKPIT FOR OTHER ISSUES.
