COMMUTER ACFT COMPLAINS OF WAKE TURB FOLLOWING JET ACFT.

Narrative

ANY TIME LNDG AT LAX OR SFO WITH HVY JET TFC. SFO IS WORSE BECAUSE USING RWYS 28L/R USUALLY HAS A 5-10 KT TAILWIND. ATC ROUTINELY PUTS COMMUTER ACFT BEHIND JET TFC ON APCH; AND PAIRS COMMUTER ACFT UP WITH PARALLEL LNDG HVY TFC. ACR COMPANY A AIRLINE'S 737'S ALWAYS FLY THEIR ILS GS 2 DOTS HIGH; SO FOLLOWING ACFT ALWAYS FLY THROUGH THEIR WAKE ON APCH. I DO NOT UNDERSTAND THIS TYPE OF OP; BUT HAVE SEEN AND FOLLOWED ACR A MANY TIMES AND ALWAYS HIT THEIR WAKE. WAKE TURB IS A BIG PROB IN CA. WE HAVE TO ROUTINELY FLY A HIGHER APCH TO REMAIN ABOVE THE WAKE. WE ALSO HAVE TO REQUEST A LONG LNDG TO TOUCHDOWN BEYOND THE POINT WHERE THE PRECEDING ACFT LANDED. IF TURBOPROP ACFT CONTINUE TO BE PUT BEHIND HVY ACFT; THIS PROB WILL CONTINUE. SEQUENCING WHEN ABLE SHOULD ALWAYS PUT TURBOPROPS IN FRONT OF JET TFC TO AVOID THEIR WAKE. I PERSONALLY DO NOT UNDERSTAND WHY JET EQUIP ARE GIVEN PRIORITY OVER TURBOPROPS. THEY CANNOT GO ANY FASTER THAN THE TURBOPROPS. WHY SHOULD JETS BE SEQUENCED AHEAD OF TURBOPROPS? HOWEVER; I HAVE FLOWN MY APCHS NON STANDARD TO STAY OUT OF THEIR WAY. THIS PLACES MY ACFT IN POOR SHAPE FOR LNDG AND IS NOT THE SAFEST ANSWER TO AVOIDING WAKE TURB. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT HE HAS FLOWN MOSTLY THE MIDWEST. WHEN HE UPGRADED TO CAPT HE WAS SHIFTED TO THE WEST COAST. HE CLAIMS TO NOT HAVE HAD SUCH DIFFICULTIES PRIOR TO FLYING IN THE W. ANALYST TRIED TO EXPLAIN THAT TFC IS SEQUENCED BY CTR IS USUALLY POSITIONED WHEN HANDED OFF TO APCH; THAT THERE IS NO DELIBERATE SEQUENCING OF TURBOS BEHIND JETS. HE DOES NOT BELIEVE THIS AND INDICATES THAT HE HAS BEEN TREATED DIFFERENTLY. HE FEELS THAT PROCS IN AIM SHOULD BE FOLLOWED OF FIRST COME; FIRST SERVED. WHEN QUESTIONED ABOUT WHETHER HE HAS CONTACTED ATC TO GET THEIR VERSION OF PROCS; HE INDICATED THEY HAVE SAID THE SAME THING. COMPANY PLTS HAVE JUST VOTED TO BE IN A PLT'S UNION AND THIS IS AN ISSUE THEY WILL BRING UP. ACFT IS A JETSTREAM 3200.
