Narrative:
Coming into sfo on runway 28L, WX clear with great visibility, cleared to land on runway 28L. Captain flying. Coming up to runway we noticed 2 aircraft holding short runway 28R between the runways. As threshold came closer, it appeared the trailing aircraft tail was slightly beyond the hold line. Situation was discussed and we landed the aircraft well beyond the threshold (12000 ft runway) and well within the touchdown zone. After landing, captain decided he wanted to call the tower and determine if it was standard practice to have 2 aircraft placed as they were. Tower assured us it was and that if an aircraft tail was ever over the line it would trigger a signal in the tower. If one was over the hold line, tower would then not permit lndgs. Captain did not like the answer and after consulting with others, elected to file report. Landing was uneventful, in the landing parameters, and at no time did I feel uncomfortable with the situation or that it was an unsafe situation.
Original NASA ASRS Text
Title: B737-300 COMPLAINS ABOUT TWR LCL CTLR PERMITTED LNDG WHEN THE TAIL OF ANOTHER ACFT WAS OVER THE HOLD SHORT LINE OF THE RWY WHILE HOLDING BEHIND ANOTHER ACFT FOR THE PARALLEL RWY.
Narrative: COMING INTO SFO ON RWY 28L, WX CLR WITH GREAT VISIBILITY, CLRED TO LAND ON RWY 28L. CAPT FLYING. COMING UP TO RWY WE NOTICED 2 ACFT HOLDING SHORT RWY 28R BTWN THE RWYS. AS THRESHOLD CAME CLOSER, IT APPEARED THE TRAILING ACFT TAIL WAS SLIGHTLY BEYOND THE HOLD LINE. SIT WAS DISCUSSED AND WE LANDED THE ACFT WELL BEYOND THE THRESHOLD (12000 FT RWY) AND WELL WITHIN THE TOUCHDOWN ZONE. AFTER LNDG, CAPT DECIDED HE WANTED TO CALL THE TWR AND DETERMINE IF IT WAS STANDARD PRACTICE TO HAVE 2 ACFT PLACED AS THEY WERE. TWR ASSURED US IT WAS AND THAT IF AN ACFT TAIL WAS EVER OVER THE LINE IT WOULD TRIGGER A SIGNAL IN THE TWR. IF ONE WAS OVER THE HOLD LINE, TWR WOULD THEN NOT PERMIT LNDGS. CAPT DID NOT LIKE THE ANSWER AND AFTER CONSULTING WITH OTHERS, ELECTED TO FILE RPT. LNDG WAS UNEVENTFUL, IN THE LNDG PARAMETERS, AND AT NO TIME DID I FEEL UNCOMFORTABLE WITH THE SIT OR THAT IT WAS AN UNSAFE SIT.
