Flight from JFK to the northeast; clearance Kennedy 1 Departure Breezy Point Climb RBV J230 BYRDD... After executing the departure and on radar vectors; ATC cleared us to the BYRDD Intersection. Shortly thereafter ATC asked if we were proceeding directly to BYRDD. We responded yes. ATC responded 'not the BYRDD I want you to go to.' A heading was issued and ATC asked what we showed for the BYRDD Intersection. The intersection had been entered in the FMS as 'BYRRD' rather than 'BYRDD'. We were shortly re-cleared directly to BYRDD. It would seem from the conversation that this wasn't the first time an aircraft had headed to the incorrect BYRDD Intersection. The remainder of the flight was uneventful.
The Reporter stated that when BYRRD was entered in the GNX ZLS FMC he saw the route displayed as south but did not see the distance. After ATC reissued the clearance the crew realized the error but not till after the flight were they able to see that not only was it South; but it was 8116 NM South. This particular aircraft's FMC has a world wide database; which in itself is somewhat unusual; but it did not issue an alert; such as insufficient fuel; which other FMS equipment would.
A corporate aircraft crew departed on the JFK Kennedy 1 Breeze Point Departure on a routing which included BYRDD Intersection. After being cleared direct BYRDD; BYRRD was entered in the FMS which caused ATC to alert them about a track deviation.
