Narrative:

Descending down through 5000 ft after being cleared for the visual approach runway 16R, and also to follow an air carrier B737 (aircraft Y), we received a traffic call from approach. Our traffic was a B727 (aircraft Z), also cleared for the visual runway 16R. He was also at 5000 ft, and at our 3 O'clock position and got very close off of our right side. My captain asked me to increase our horizontal separation, which I happily did, and about this point were cleared to land runway 16L. We flew a normal approach to landing, with the B727 (aircraft Z) close abeam our right side. On rollout we noticed the B737 (aircraft Y) holding to cross runway 16L. (He had landed runway 16R as we were initially instructed to.) this situation created a very confusing and somewhat stressful event during a critical phase of flight. I believe the controller was just overloaded with about 5 jets showing up at once.

Original NASA ASRS Text

Title: AN FK28 FO WAS UNCOMFORTABLE MAKING A PARALLEL APCH AT SEA WITH A B727, WHILE CLOSELY FOLLOWING A B737.

Narrative: DSNDING DOWN THROUGH 5000 FT AFTER BEING CLRED FOR THE VISUAL APCH RWY 16R, AND ALSO TO FOLLOW AN ACR B737 (ACFT Y), WE RECEIVED A TFC CALL FROM APCH. OUR TFC WAS A B727 (ACFT Z), ALSO CLRED FOR THE VISUAL RWY 16R. HE WAS ALSO AT 5000 FT, AND AT OUR 3 O'CLOCK POS AND GOT VERY CLOSE OFF OF OUR R SIDE. MY CAPT ASKED ME TO INCREASE OUR HORIZ SEPARATION, WHICH I HAPPILY DID, AND ABOUT THIS POINT WERE CLRED TO LAND RWY 16L. WE FLEW A NORMAL APCH TO LNDG, WITH THE B727 (ACFT Z) CLOSE ABEAM OUR R SIDE. ON ROLLOUT WE NOTICED THE B737 (ACFT Y) HOLDING TO CROSS RWY 16L. (HE HAD LANDED RWY 16R AS WE WERE INITIALLY INSTRUCTED TO.) THIS SIT CREATED A VERY CONFUSING AND SOMEWHAT STRESSFUL EVENT DURING A CRITICAL PHASE OF FLT. I BELIEVE THE CTLR WAS JUST OVERLOADED WITH ABOUT 5 JETS SHOWING UP AT ONCE.
