Narrative:

I dispatched flight dtw-sfo, filed dbq.J94.lcu.J158.MVA. The flight plan route was dbq.J94.ocs.J154.slc.J56.MVA. At air carrier company the filed route and the flight plan route are independent of each other so this kind of error can occur. Unfortunately, the workload on the desk I was working prevented me from verifying that the filed route and the flight plan route were the same on the 44 releases done on this shift. In this instance the flight crew also missed the error and programmed their INS to fly the flight plan route while ATC thought they would be flying the filed route. Needless to say this is a safety issue. Our navigation database needs to be more intensely scrutinized, the computer system has to be enhanced to eliminate this kind of error or the workload adjusted so these errors can be found prior to flight.

Original NASA ASRS Text

Title: FLT PLAN CHANGE FROM ORIGINALLY FILED NOT PICKED UP BY DISPATCHER OR FLC.

Narrative: I DISPATCHED FLT DTW-SFO, FILED DBQ.J94.LCU.J158.MVA. THE FLT PLAN RTE WAS DBQ.J94.OCS.J154.SLC.J56.MVA. AT ACR COMPANY THE FILED RTE AND THE FLT PLAN RTE ARE INDEPENDENT OF EACH OTHER SO THIS KIND OF ERROR CAN OCCUR. UNFORTUNATELY, THE WORKLOAD ON THE DESK I WAS WORKING PREVENTED ME FROM VERIFYING THAT THE FILED RTE AND THE FLT PLAN RTE WERE THE SAME ON THE 44 RELEASES DONE ON THIS SHIFT. IN THIS INSTANCE THE FLC ALSO MISSED THE ERROR AND PROGRAMMED THEIR INS TO FLY THE FLT PLAN RTE WHILE ATC THOUGHT THEY WOULD BE FLYING THE FILED RTE. NEEDLESS TO SAY THIS IS A SAFETY ISSUE. OUR NAV DATABASE NEEDS TO BE MORE INTENSELY SCRUTINIZED, THE COMPUTER SYS HAS TO BE ENHANCED TO ELIMINATE THIS KIND OF ERROR OR THE WORKLOAD ADJUSTED SO THESE ERRORS CAN BE FOUND PRIOR TO FLT.
