AN ACR PLT WAS SLOWER OVER THE OM THAN THE ATCT LCL CTLR EXPECTED.

Narrative

ROUTINE ARR INTO LAX ON THE CIVET PROFILE. APCH CTL STATES; 'AFTER ARNES; CLRED THE ILS RWY 25L TO LAX.' UPON CONTACTING THE TWR; WE WERE TOLD TO KEEP 220 KTS UNTIL THE MARKER. ABOUT 8 MI FROM THE MARKER; WE BEGAN TO SLOW TO APCH SPD. AFTER ABOUT 30 KTS OF SPD REDUCTION; THE TWR INSTRUCTED WE WERE 'ASSIGNED 220 KTS' IN A RATHER SHARP AND MANDATORY VOICE. WE INDICATED THAT WE HAVE ALREADY BEEN CLRED FOR APCH AND WERE NOT ABLE TO HOLD 220 KTS OVER THE MARKER DUE TO GEAR TO APCH SPDS (FLAPS). LNDG WAS UNEVENTFUL; HOWEVER THE APCH STILL SEEMED RUSHED DUE TO THE INCREASED SPD. I THINK THAT SOME CTLRS NEED TO BE MORE AWARE OF CERTAIN AIRPLANE CHARACTERISTICS IF THEY PLAN ON CONDUCTING MINIMUM SPACED APCHS. BY REDUCING THE AMOUNT OF TIME NEEDED TO COMPLETE CHKLIST AND FOR PROPER AIRPLANE CONFIGN; IT ONLY INCREASES THE CHANCES FOR POSSIBLE HUMAN ERROR DURING A CRITICAL PHASE OF FLT. HOPEFULLY; CTLRS IN THE FUTURE SHOULD NOT ONLY BE AWARE OF ACFT DISTANCES; BUT ALSO MANY DIFFERENT OPERATING PRACTICES OF THE VARIOUS AIRLINES THAT TAKES TIME TO PERFORM.
