Narrative:
After having reached a cruise altitude of FL290; ATC inquired as to why we were south of our cleared course. I read the controller our clearance which he replied was slightly different than what was on his strip. He turned us direct to a fix and then said that we were starting to mingle with lga arrs which made it difficult to get us down on the BOUNO3 arrival into hpn. I stated that this has happened before with this very route although it was a few yrs ago. I was acting as the sic and I recall the captain loading the flight plan from the release and I do not think I verified the FMS route from the clearance I received. I know that often; especially in the northeast corridor; your filed route is not what you are cleared to. As I recall; the filed route and the one received were the same. It may have been that these rtes looked the same (they were very close; indeed) but the difference was enough to be noticed. How the clearance we had as opposed to the ATC one were different I do not know. In the future I will not allow the FMS to be loaded until after the clearance is received. In this manner there will be no reason to be off course.

Title: A FALCON 2000 DEVIATED FROM CLRED RTE WHEN THE CREW LOADED THEIR PLANNED RTE IN THE FMC INSTEAD OF THE CLRED RTE.
Narrative: AFTER HAVING REACHED A CRUISE ALT OF FL290; ATC INQUIRED AS TO WHY WE WERE S OF OUR CLRED COURSE. I READ THE CTLR OUR CLRNC WHICH HE REPLIED WAS SLIGHTLY DIFFERENT THAN WHAT WAS ON HIS STRIP. HE TURNED US DIRECT TO A FIX AND THEN SAID THAT WE WERE STARTING TO MINGLE WITH LGA ARRS WHICH MADE IT DIFFICULT TO GET US DOWN ON THE BOUNO3 ARR INTO HPN. I STATED THAT THIS HAS HAPPENED BEFORE WITH THIS VERY RTE ALTHOUGH IT WAS A FEW YRS AGO. I WAS ACTING AS THE SIC AND I RECALL THE CAPT LOADING THE FLT PLAN FROM THE RELEASE AND I DO NOT THINK I VERIFIED THE FMS RTE FROM THE CLRNC I RECEIVED. I KNOW THAT OFTEN; ESPECIALLY IN THE NE CORRIDOR; YOUR FILED RTE IS NOT WHAT YOU ARE CLRED TO. AS I RECALL; THE FILED RTE AND THE ONE RECEIVED WERE THE SAME. IT MAY HAVE BEEN THAT THESE RTES LOOKED THE SAME (THEY WERE VERY CLOSE; INDEED) BUT THE DIFFERENCE WAS ENOUGH TO BE NOTICED. HOW THE CLRNC WE HAD AS OPPOSED TO THE ATC ONE WERE DIFFERENT I DO NOT KNOW. IN THE FUTURE I WILL NOT ALLOW THE FMS TO BE LOADED UNTIL AFTER THE CLRNC IS RECEIVED. IN THIS MANNER THERE WILL BE NO REASON TO BE OFF COURSE.
