Narrative:

Aircraft X was en route to tys at 14000. Air carrier Y was vectored off course to descend next to another dades arrival to tpa. Air carrier Y was not given a crossing restriction and was not RNAV equipped so it would have been difficult to give the aircraft a restriction. So he was a little high for the dades arrival and got within 5 mi of aircraft X en route.

Original NASA ASRS Text

Title: ACR Y HAD LTSS FROM ACFT X. SYS ERROR.

Narrative: ACFT X WAS ENRTE TO TYS AT 14000. ACR Y WAS VECTORED OFF COURSE TO DSND NEXT TO ANOTHER DADES ARR TO TPA. ACR Y WAS NOT GIVEN A XING RESTRICTION AND WAS NOT RNAV EQUIPPED SO IT WOULD HAVE BEEN DIFFICULT TO GIVE THE ACFT A RESTRICTION. SO HE WAS A LITTLE HIGH FOR THE DADES ARR AND GOT WITHIN 5 MI OF ACFT X ENRTE.
