AN S80 PIC RPT ON AN ALT OVERSHOOT WHEN THE CREW DID NOT FOLLOW THE STAR ARR NOTE REGARDING THE ALT XING RESTR OVER DQO; DE.

Narrative

AFTER RECEIVING AND ACCEPTING A DSND VIA THE DYLIN 1 CLRNC AND AFTER JUST PASSING DUPONT VOR; THE CTLR INFORMED US WE WERE TO BE AT FL220. AT THIS POINT; WE WERE DSNDING THROUGH FL200. AFTER RECHKING THE ARR; I DID SEE THE NO LOWER THAN FL220 BENEATH THE DQO FREQ BOX. THE FO AND I BRIEFED THIS NEW ARR BEFORE WE BEGAN THE DSCNT THOUGH I DID NOT SEE THAT RESTR. THE FO WAS FLYING THE AIRPLANE AND SAID HE HAD SEEN IT AND JUST FORGOT ABOUT IT ONCE WE RECEIVED THE CLRNC. DURING THE POSTFLT DEBRIEF; I QUESTIONED HOW WE COULD MISS THAT RESTR. UPON CHKING IT AGAIN A THIRD TIME AT THE GATE; I NOTICED THAT THERE IS NO SMALL INSTRUCTIONAL ARROW POINTING TO THE FIX -- JUST THE LARGER FREQ ARROW. AFTER LOOKING AT NUMEROUS OTHER ARRS; I SAW THAT THE ABSENCE OF THE SMALLER INSTRUCTIONAL ARROW IS RARE. ON ALL THE OTHER DSND VIA ARRS I LOOKED AT; I DID NOT NOTICE ANOTHER ABSENCE OF THE SMALL ARROW OVER A FACILITY. IE; PARADISE ARR TO LAX OR THE WONDERFUL STARS INTO LAS. NO EXCUSE THOUGH. JUST POINTING OUT THE LACK OF OBVIOUSNESS OF THAT RESTR ON THE DYLIN 1. PERHAPS MESSAGE ON THAT ARR MAY PREVENT A SIMILAR OVERSIGHT.
