Narrative:
While making a visual approach to runway 28R to sfo airport at about 2 mi east of brijj intersection, we received a red alert from our TCASII system. After following the commands of our TCASII, continued to runway and landed. This warning was only for a second or two, but it was disconcerting during a critical phase of flight. There really was no real danger during this approach, since we had the other aircraft in sight and he had us in sight. I think at sfo they (controllers) should provide more separation for the aircraft.

Title: EVASIVE ACTION. MULTIPLE RWY OP PARALLEL RWYS. ACR MAKING A PARALLEL APCH WITH ADJACENT TFC IN SIGHT STILL FOLLOWS TCASII RA, BUT COMPLETES APCH.
Narrative: WHILE MAKING A VISUAL APCH TO RWY 28R TO SFO ARPT AT ABOUT 2 MI E OF BRIJJ INTXN, WE RECEIVED A RED ALERT FROM OUR TCASII SYS. AFTER FOLLOWING THE COMMANDS OF OUR TCASII, CONTINUED TO RWY AND LANDED. THIS WARNING WAS ONLY FOR A SECOND OR TWO, BUT IT WAS DISCONCERTING DURING A CRITICAL PHASE OF FLT. THERE REALLY WAS NO REAL DANGER DURING THIS APCH, SINCE WE HAD THE OTHER ACFT IN SIGHT AND HE HAD US IN SIGHT. I THINK AT SFO THEY (CTLRS) SHOULD PROVIDE MORE SEPARATION FOR THE ACFT.
