Flight crew of B737-800 misprogram FMS on noise abatement departure from abq. Use of airport vice VOR as source of 13 pt 5 mi arc results in a 10 mi error toward high terrain. Timely intervention by abq departure controller avoids more serious outcome.

Narrative:
Departing abq on runway 8; clearance was to follow noise abatement procedure and turn to 310 degree heading. Noise abatement procedure is to turn at 13.5 DME from abq VOR. Copilot programmed a 13.5 DME ring around abq airport vice 13.5 DME from abq VOR. On climb out; terrain appeared to get close and we were still a few mi from the 13.5 DME ring displayed on FMS navigation display. As I checked our distance; from abq VOR; I noticed the 13.5 DME ring on the navigation display within the terrain area. Before I got a chance to tell copilot to start turn; departure control told us to start our turn to 310 degrees and asked if we had terrain in sight. We did have terrain in sight both visually and on the navigation display. (This aircraft has the ability to display terrain on navigation display.) we were able to see and avoid the terrain. Altitude was 10500 ft MSL when we started the turn and we were approximately on abq VOR 080 degree radial and 19 DME. Egpws never alerted to any terrain conflict.

Title: FLT CREW OF B737-800 MISPROGRAM FMS ON NOISE ABATEMENT DEP FROM ABQ. USE OF ARPT VICE VOR AS SOURCE OF 13 PT 5 MI ARC RESULTS IN A 10 MI ERROR TOWARD HIGH TERRAIN. TIMELY INTERVENTION BY ABQ DEP CTLR AVOIDS MORE SERIOUS OUTCOME.
Narrative: DEPARTING ABQ ON RWY 8; CLRNC WAS TO FOLLOW NOISE ABATEMENT PROC AND TURN TO 310 DEG HDG. NOISE ABATEMENT PROC IS TO TURN AT 13.5 DME FROM ABQ VOR. COPLT PROGRAMMED A 13.5 DME RING AROUND ABQ ARPT VICE 13.5 DME FROM ABQ VOR. ON CLBOUT; TERRAIN APPEARED TO GET CLOSE AND WE WERE STILL A FEW MI FROM THE 13.5 DME RING DISPLAYED ON FMS NAV DISPLAY. AS I CHKED OUR DISTANCE; FROM ABQ VOR; I NOTICED THE 13.5 DME RING ON THE NAV DISPLAY WITHIN THE TERRAIN AREA. BEFORE I GOT A CHANCE TO TELL COPLT TO START TURN; DEP CTL TOLD US TO START OUR TURN TO 310 DEGS AND ASKED IF WE HAD TERRAIN IN SIGHT. WE DID HAVE TERRAIN IN SIGHT BOTH VISUALLY AND ON THE NAV DISPLAY. (THIS ACFT HAS THE ABILITY TO DISPLAY TERRAIN ON NAV DISPLAY.) WE WERE ABLE TO SEE AND AVOID THE TERRAIN. ALT WAS 10500 FT MSL WHEN WE STARTED THE TURN AND WE WERE APPROX ON ABQ VOR 080 DEG RADIAL AND 19 DME. EGPWS NEVER ALERTED TO ANY TERRAIN CONFLICT.
