Narrative:
On approach to sfo, VMC, bay approach gave us our co-approach aircraft Y on the tipp toe visibility (we were on the quite bridge) at about 20 mi out. I clearly saw him and figured we would be landing approximately together, he on 28L and us on 28R! At about 3 mi to go to the high span, on course but high, bay switched us to tower. I changed frequency, looked back out and our co-approach aircraft Y was crossing my course 30 degrees off my heading, about 1000' lower. He passed to our right. We stopped our descent and slowed to keep him in sight! He then wrapped it up in a left turn back to the runway. It appeared that conflict aircraft Y buried their heads in the cockpit for a brief time and created a potentially hazardous situation. After talking to the captain of aircraft Y, that's exactly what happened. A glass cockpit problem and a 'yakking' inexperienced copilot contributed, according to the captain. My observation: why does a pilot continue to use a tool when obviously the tool is defective at that moment, be it a glass cockpit or distracting copilot? There is a time for basic airmanship and see and avoid--it is all the time!

Title: ACR ACFT Y ON VISUAL TIPTOE APCH TO 28L AT SFO STRAYS INTO APCH PATH FOR OTHER RWY.
Narrative: ON APCH TO SFO, VMC, BAY APCH GAVE US OUR CO-APCH ACFT Y ON THE TIPP TOE VIS (WE WERE ON THE QUITE BRIDGE) AT ABOUT 20 MI OUT. I CLEARLY SAW HIM AND FIGURED WE WOULD BE LNDG APPROX TOGETHER, HE ON 28L AND US ON 28R! AT ABOUT 3 MI TO GO TO THE HIGH SPAN, ON COURSE BUT HIGH, BAY SWITCHED US TO TWR. I CHANGED FREQ, LOOKED BACK OUT AND OUR CO-APCH ACFT Y WAS XING MY COURSE 30 DEGS OFF MY HDG, ABOUT 1000' LOWER. HE PASSED TO OUR RIGHT. WE STOPPED OUR DSNT AND SLOWED TO KEEP HIM IN SIGHT! HE THEN WRAPPED IT UP IN A LEFT TURN BACK TO THE RWY. IT APPEARED THAT CONFLICT ACFT Y BURIED THEIR HEADS IN THE COCKPIT FOR A BRIEF TIME AND CREATED A POTENTIALLY HAZARDOUS SITUATION. AFTER TALKING TO THE CAPT OF ACFT Y, THAT'S EXACTLY WHAT HAPPENED. A GLASS COCKPIT PROB AND A 'YAKKING' INEXPERIENCED COPLT CONTRIBUTED, ACCORDING TO THE CAPT. MY OBSERVATION: WHY DOES A PLT CONTINUE TO USE A TOOL WHEN OBVIOUSLY THE TOOL IS DEFECTIVE AT THAT MOMENT, BE IT A GLASS COCKPIT OR DISTRACTING COPLT? THERE IS A TIME FOR BASIC AIRMANSHIP AND SEE AND AVOID--IT IS ALL THE TIME!
