Narrative:
During descent on dupont arrival, ZDC called and said we were 6.5 mi north of nottingham. We were at 340 KIAS and 3000 FPM sink rate descending from 18,000 to 10,000'. The sky was clear and there was no other traffic. We corrected back to course using 10 degree aob as prescribed by company procedures when above 10,000'. During this descent we were required to: 1) talk to the passenger. 2) complete descent checklist (5 items). 3) complete approach checklist (7 items). 4) brief approach plate (8 items). 5) tune and identify 2 vors. 6) place 2 courses inbound and outbnd. The dupont approach should be looked at closely to see if it is a good approach with so many turns and such short distances required. We weren't ever far from the approach plates departure course and yet the controller seemed concerned. If there was an error it was unintentional and safety was never a factor as there was no reported traffic and it was VFR with unlimited visibility. Our instruments never showed us anywhere near 6.5 mi off course.

Title: TRACK ERROR. FLT OFF COURSE IN DESCENT.
Narrative: DURING DSCNT ON DUPONT ARR, ZDC CALLED AND SAID WE WERE 6.5 MI N OF NOTTINGHAM. WE WERE AT 340 KIAS AND 3000 FPM SINK RATE DESCENDING FROM 18,000 TO 10,000'. THE SKY WAS CLEAR AND THERE WAS NO OTHER TFC. WE CORRECTED BACK TO COURSE USING 10 DEG AOB AS PRESCRIBED BY COMPANY PROCS WHEN ABOVE 10,000'. DURING THIS DSCNT WE WERE REQUIRED TO: 1) TALK TO THE PAX. 2) COMPLETE DSCNT CHECKLIST (5 ITEMS). 3) COMPLETE APCH CHECKLIST (7 ITEMS). 4) BRIEF APCH PLATE (8 ITEMS). 5) TUNE AND IDENTIFY 2 VORS. 6) PLACE 2 COURSES INBND AND OUTBND. THE DUPONT APCH SHOULD BE LOOKED AT CLOSELY TO SEE IF IT IS A GOOD APCH WITH SO MANY TURNS AND SUCH SHORT DISTANCES REQUIRED. WE WEREN'T EVER FAR FROM THE APCH PLATES DEP COURSE AND YET THE CTLR SEEMED CONCERNED. IF THERE WAS AN ERROR IT WAS UNINTENTIONAL AND SAFETY WAS NEVER A FACTOR AS THERE WAS NO REPORTED TFC AND IT WAS VFR WITH UNLIMITED VISIBILITY. OUR INSTRUMENTS NEVER SHOWED US ANYWHERE NEAR 6.5 MI OFF COURSE.
