Narrative:

On our flight from cle to dfw on sep/xa/00, we were descending on the 035 degree radial inbound to the ranger (fuz) VOR on the jonez 4 arrival to dfw. Both our #1 and #2 VOR needles were centered. We were descending from FL200 to 11000 ft about 55 mi out when ATC told us we were not centered on the jonez 4 arrival. Our equipment said we were on the centerline. The controller said we were 3 mi west of course. We then asked for vectors to dfw because we obviously had both vors rendered not reliable. We landed and I wrote up the VOR equipment of the aircraft as being unreliable.

Title: MD80 CREW WAS ADVISED THEY WERE 3 MI R OF COURSE IN ZFW CLASS A AND CLASS E AIRSPACE.

Narrative: ON OUR FLT FROM CLE TO DFW ON SEP/XA/00, WE WERE DSNDING ON THE 035 DEG RADIAL INBOUND TO THE RANGER (FUZ) VOR ON THE JONEZ 4 ARR TO DFW. BOTH OUR #1 AND #2 VOR NEEDLES WERE CTRED. WE WERE DSNDING FROM FL200 TO 11000 FT ABOUT 55 MI OUT WHEN ATC TOLD US WE WERE NOT CTRED ON THE JONEZ 4 ARR. OUR EQUIP SAID WE WERE ON THE CTRLINE. THE CTLR SAID WE WERE 3 MI W OF COURSE. WE THEN ASKED FOR VECTORS TO DFW BECAUSE WE OBVIOUSLY HAD BOTH VORS RENDERED NOT RELIABLE. WE LANDED AND I WROTE UP THE VOR EQUIP OF THE ACFT AS BEING UNRELIABLE.
