Narrative:

Due to an error in crew coordination, the wrong routing was entered into the FMS system, resulting in aircraft proceeding along in wrong routing for a short period of time. Error was caught by ATC and corrected by crew. At no time was there a safety risk or traffic conflict. This was a case of crew misinterpreting a clearance and entering a 'computer' flight plan into the FMS instead of the actual cleared routing.

Title: A GULFSTREAM 4 IS NOTED TO BE OFF THE CLRED ROUTING BY ZDC CTLR.

Narrative: DUE TO AN ERROR IN CREW COORD, THE WRONG ROUTING WAS ENTERED INTO THE FMS SYS, RESULTING IN ACFT PROCEEDING ALONG IN WRONG ROUTING FOR A SHORT PERIOD OF TIME. ERROR WAS CAUGHT BY ATC AND CORRECTED BY CREW. AT NO TIME WAS THERE A SAFETY RISK OR TFC CONFLICT. THIS WAS A CASE OF CREW MISINTERPRETING A CLRNC AND ENTERING A 'COMPUTER' FLT PLAN INTO THE FMS INSTEAD OF THE ACTUAL CLRED ROUTING.
