Narrative:

During holding ZFW asked us to descend 1000 ft and report leaving. As per captain's instructions I reported leaving the altitude while he finished programming the change into the autoplt. The aircraft was very slow responding and the other aircraft above us started to descend faster than ours. No conflict was reported, but it is another example of how state of the art automation puts not only more workload on pilots, but seems to open up more chances for compromising safety.

Title: FLC OF AN LGT ALMOST HAD AN AIRBORNE CONFLICT DUE TO THE DELAY IN RESPONDING TO AN ATC DSCNT CLRNC.

Narrative: DURING HOLDING ZFW ASKED US TO DSND 1000 FT AND RPT LEAVING. AS PER CAPT'S INSTRUCTIONS I RPTED LEAVING THE ALT WHILE HE FINISHED PROGRAMMING THE CHANGE INTO THE AUTOPLT. THE ACFT WAS VERY SLOW RESPONDING AND THE OTHER ACFT ABOVE US STARTED TO DSND FASTER THAN OURS. NO CONFLICT WAS RPTED, BUT IT IS ANOTHER EXAMPLE OF HOW STATE OF THE ART AUTOMATION PUTS NOT ONLY MORE WORKLOAD ON PLTS, BUT SEEMS TO OPEN UP MORE CHANCES FOR COMPROMISING SAFETY.
