Narrative:
Approaching den we were cleared for a visibility approach to 26R. An large transport was cleared for a visibility approach to 26L. We were about 50' ahead of the large transport and remained there throughout the approach and landing. About halfway between the OM and the runway an small transport came in from our right side for a visibility approach to runway 25. We had visibility contact with both aircraft, but with only 2 pilots it is impossible to watch an aircraft on both sides of your aircraft and pay full attention to your own approach and landing. The small transport was slightly ahead of us and landed about 2 seconds ahead of us. The large transport landed at the same time we did. I think parallel approachs at den push the margin of safety and parallel approachs with 3 aircraft should not be allowed. The center aircraft has no place to go if either aircraft overshoots his runway centerline. Later in the day we were again cleared into the same situation, but the aircraft landing on 26L was faster than we were and we were able to slow our approach speed enough that the small transport landing on runway 25 stayed ahead of us until after we landed. Approach control should be able to stagger the smaller aircraft landing on runway 25 so that they are ahead of behind us by about at least 1 mi when we land. The WX was not a factor today, however, if we would have had a strong crosswind several hundred ft above the ground as we frequently have at den, the results could have been different.
Original NASA ASRS Text
Title: MLG REPORTER WAS IN MIDDLE OF 3 VISUAL APCH ACFT APCHING, DESCENDING AND LNDG AT DEN.
Narrative: APCHING DEN WE WERE CLRED FOR A VIS APCH TO 26R. AN LGT WAS CLRED FOR A VIS APCH TO 26L. WE WERE ABOUT 50' AHEAD OF THE LGT AND REMAINED THERE THROUGHOUT THE APCH AND LNDG. ABOUT HALFWAY BTWN THE OM AND THE RWY AN SMT CAME IN FROM OUR RIGHT SIDE FOR A VIS APCH TO RWY 25. WE HAD VIS CONTACT WITH BOTH ACFT, BUT WITH ONLY 2 PLTS IT IS IMPOSSIBLE TO WATCH AN ACFT ON BOTH SIDES OF YOUR ACFT AND PAY FULL ATTN TO YOUR OWN APCH AND LNDG. THE SMT WAS SLIGHTLY AHEAD OF US AND LANDED ABOUT 2 SECS AHEAD OF US. THE LGT LANDED AT THE SAME TIME WE DID. I THINK PARALLEL APCHS AT DEN PUSH THE MARGIN OF SAFETY AND PARALLEL APCHS WITH 3 ACFT SHOULD NOT BE ALLOWED. THE CENTER ACFT HAS NO PLACE TO GO IF EITHER ACFT OVERSHOOTS HIS RWY CENTERLINE. LATER IN THE DAY WE WERE AGAIN CLRED INTO THE SAME SITUATION, BUT THE ACFT LNDG ON 26L WAS FASTER THAN WE WERE AND WE WERE ABLE TO SLOW OUR APCH SPD ENOUGH THAT THE SMT LNDG ON RWY 25 STAYED AHEAD OF US UNTIL AFTER WE LANDED. APCH CTL SHOULD BE ABLE TO STAGGER THE SMALLER ACFT LNDG ON RWY 25 SO THAT THEY ARE AHEAD OF BEHIND US BY ABOUT AT LEAST 1 MI WHEN WE LAND. THE WX WAS NOT A FACTOR TODAY, HOWEVER, IF WE WOULD HAVE HAD A STRONG XWIND SEVERAL HUNDRED FT ABOVE THE GND AS WE FREQUENTLY HAVE AT DEN, THE RESULTS COULD HAVE BEEN DIFFERENT.
