Narrative

WE DEPARTED SLC AT XA56Z ON RWY 35 USING THE SEVYR ONE DEP. THE CONDITIONS OF THE DAY WERE CLR SKIES; 10 MI VISIBILITY. THE CLRNC WAS THE DEP UP TO 8000 FT. WE DEPARTED; CLBED TO 500 FT AGL; TURNED L TO A 260 DEG HDG. I CONTACTED DEP ON THE 260 DEG HDG. CLBING THROUGH APPROX 6000 FT THE 193 DEG RADIAL CAME ALIVE SO WE STARED OUR TURN. THE CALL TO DEP WAS MADE IN THE TURN INDICATING OUR CLB TO 8000 FT AND TURN TO THE 193 DEG RADIAL. THE RESPONSE WAS CLB TO 10000 FT AND REPEAT LAST XMISSION. I VERIFIED UP TO 10000 FT AND OUR TURN ON THE 193 DEG RADIAL. DEP TOLD US RETURN TO 260 DEG HDG AND THERE IS RISING TERRAIN TO THE S. I ACKNOWLEDGED THE XMISSION AND WAS ASKED TO CONTACT DEP ON THE LAND LINE WHEN I ARRIVED AT DEST. WE REMAINED ON THE 260 DEG HDG; PASSING THROUGH THE 193 DEG RADIAL AND RE-INTERCEPTING THE RADIAL FROM THE W. THE REST OF THE FLT WAS UNEVENTFUL. SUPPLEMENTAL INFO FROM ACN 587096: THIS DEV WAS CAUSED BY MISINTERP OF SID. MISINTERP OCCURRED DUE TO PICTORIAL SHOWING FLT PATH FOLLOWING HEADING 260 DEGS TO SLC 193 DEG RADIAL; WHEN IT ACTUALLY SHOULD HAVE CROSSED 193 DEG RADIAL AND CONTINUED. TEXTUAL DESCRIPTION WAS CLR; BUT PICTORIAL LED US TO BELIEVE WE NEEDED TO TURN ONTO 193 DEG RADIAL. PNF HELPED LIMIT DEV BY RPTING TURN TO 193 DEG RADIAL TO ATC; WHICH THEN IDENTED DEV IMMEDIATELY.
