Narrative:

Captain was flying. I worked radios. ZTL initially cleared us to descend from FL210 to 17000 ft. Shortly after we began descent, controller cleared us direct roa, cross 30 NM southwest of roa at and maintain 10000 ft. I acknowledged. At this point we were about 60 NM from roa. Captain set up a relatively shallow descent and I should have caught at that time that our profile needed to be steepened. Through 18000 ft, the captain called for and we did the preliminary landing checklist. After that, I totally forgot that we had a crossing restr. We recalled the restr just before we were at 30 DME, and descending through 14000 ft, it was clear that we could not make the restr. I called center and told him that I was sorry, but we had forgotten about the crossing restr that we obviously could not make it, and I asked him if he would like for us to make a 360 degree turn to get down to 10000 ft. He said no, to just continue the descent. As we approached 10000 ft, he switched us to roa approach. Our TCASII did not display any conflicting traffic. This is the first time in a long time that I have missed a crossing restr, but I am unhappy with myself that I let my mind wander sufficiently to allow it to occur. Vigilance will be re- emphasized.

Original NASA ASRS Text

Title: UNDERSHOT XING RESTR ALT.

Narrative: CAPT WAS FLYING. I WORKED RADIOS. ZTL INITIALLY CLRED US TO DSND FROM FL210 TO 17000 FT. SHORTLY AFTER WE BEGAN DSCNT, CTLR CLRED US DIRECT ROA, CROSS 30 NM SW OF ROA AT AND MAINTAIN 10000 FT. I ACKNOWLEDGED. AT THIS POINT WE WERE ABOUT 60 NM FROM ROA. CAPT SET UP A RELATIVELY SHALLOW DSCNT AND I SHOULD HAVE CAUGHT AT THAT TIME THAT OUR PROFILE NEEDED TO BE STEEPENED. THROUGH 18000 FT, THE CAPT CALLED FOR AND WE DID THE PRELIMINARY LNDG CHKLIST. AFTER THAT, I TOTALLY FORGOT THAT WE HAD A XING RESTR. WE RECALLED THE RESTR JUST BEFORE WE WERE AT 30 DME, AND DSNDING THROUGH 14000 FT, IT WAS CLR THAT WE COULD NOT MAKE THE RESTR. I CALLED CTR AND TOLD HIM THAT I WAS SORRY, BUT WE HAD FORGOTTEN ABOUT THE XING RESTR THAT WE OBVIOUSLY COULD NOT MAKE IT, AND I ASKED HIM IF HE WOULD LIKE FOR US TO MAKE A 360 DEG TURN TO GET DOWN TO 10000 FT. HE SAID NO, TO JUST CONTINUE THE DSCNT. AS WE APCHED 10000 FT, HE SWITCHED US TO ROA APCH. OUR TCASII DID NOT DISPLAY ANY CONFLICTING TFC. THIS IS THE FIRST TIME IN A LONG TIME THAT I HAVE MISSED A XING RESTR, BUT I AM UNHAPPY WITH MYSELF THAT I LET MY MIND WANDER SUFFICIENTLY TO ALLOW IT TO OCCUR. VIGILANCE WILL BE RE- EMPHASIZED.
