Narrative:

During descent into rdu, we were given multiple 45 degrees to 90 degree vectors along with multiple altitude and speed changes. All combined to create a high cockpit workload. While descending, ZDC advised us to slow to 250 KTS from 340 KTS. Our rate of descent was slowed so that speed could be reduced. ZDC later complained that we slowed our descent rate to less than 1000 FPM without advising them. (The limit is 500 FPM). At no time were any center issued altitude restrs missed.

Title: HIGH COCKPIT WORKLOAD.

Narrative: DURING DSCNT INTO RDU, WE WERE GIVEN MULTIPLE 45 DEGS TO 90 DEG VECTORS ALONG WITH MULTIPLE ALT AND SPD CHANGES. ALL COMBINED TO CREATE A HIGH COCKPIT WORKLOAD. WHILE DSNDING, ZDC ADVISED US TO SLOW TO 250 KTS FROM 340 KTS. OUR RATE OF DSCNT WAS SLOWED SO THAT SPD COULD BE REDUCED. ZDC LATER COMPLAINED THAT WE SLOWED OUR DSCNT RATE TO LESS THAN 1000 FPM WITHOUT ADVISING THEM. (THE LIMIT IS 500 FPM). AT NO TIME WERE ANY CTR ISSUED ALT RESTRS MISSED.
