Narrative:

Descending on the civet arrival we were given a speed reduction outside bremr. We complied, crossed bremr above 12000 ft and still had some cushion to cross arnes below 11000 ft. However, approach gave us a further speed reduction which now made us unable to cross arnes below 11000 ft while slowing to and maintaining the assigned speed. As the first officer began slowing, I told him to make the crossing restr then continue to slow. I then attempted to gain relief from approach, but was unable due to frequency congestion. We ended up crossing arnes slightly high. Approach handed us off to tower with no mention of this and we continued to a normal landing. What would I do differently? In the future I'll make sure the brief of the arrival/approach includes this pitfall -- along with confirming the mode of autoplt operation I want to see. I also won't hesitate to ask for relief.

Original NASA ASRS Text

Title: AN ACR TWIN JET DSNDING ON THE CIVET ARR PROC FAILS TO MAKE A SPD REDUCTION AND THE ALT XING RESTR THAT ATC ASSIGNED THE FLC ON FREQ WITH SCT, CA.

Narrative: DSNDING ON THE CIVET ARR WE WERE GIVEN A SPD REDUCTION OUTSIDE BREMR. WE COMPLIED, CROSSED BREMR ABOVE 12000 FT AND STILL HAD SOME CUSHION TO CROSS ARNES BELOW 11000 FT. HOWEVER, APCH GAVE US A FURTHER SPD REDUCTION WHICH NOW MADE US UNABLE TO CROSS ARNES BELOW 11000 FT WHILE SLOWING TO AND MAINTAINING THE ASSIGNED SPD. AS THE FO BEGAN SLOWING, I TOLD HIM TO MAKE THE XING RESTR THEN CONTINUE TO SLOW. I THEN ATTEMPTED TO GAIN RELIEF FROM APCH, BUT WAS UNABLE DUE TO FREQ CONGESTION. WE ENDED UP XING ARNES SLIGHTLY HIGH. APCH HANDED US OFF TO TWR WITH NO MENTION OF THIS AND WE CONTINUED TO A NORMAL LNDG. WHAT WOULD I DO DIFFERENTLY? IN THE FUTURE I'LL MAKE SURE THE BRIEF OF THE ARR/APCH INCLUDES THIS PITFALL -- ALONG WITH CONFIRMING THE MODE OF AUTOPLT OP I WANT TO SEE. I ALSO WON'T HESITATE TO ASK FOR RELIEF.
