Narrative:
I (copilot, PNF) read a revised route to the captain as he programmed the FMS. A TCASII RA was noticed as we approached 30 mi west. An aircraft was observed to be in a descent from the same altitude as ourselves. We then reviewed all of the waypoints in the flight plan. We noticed that our waypoint (5130) had a latitude/longitude of north 50.00.0 west 30.00.0. As a result of an input error, we flew an incorrect route. The TCASII TA and RA was a result of this navigation error.

Title: DA90M ENTERED AN IMPROPER WAYPOINT ON AN ATLANTIC XING. THIS NAV ERROR RESULTED IN A CONFLICT WITH ANOTHER ACFT WHICH DSNDED TO EVADE. A TCASII RA WAS RECEIVED.
Narrative: I (COPLT, PNF) READ A REVISED RTE TO THE CAPT AS HE PROGRAMMED THE FMS. A TCASII RA WAS NOTICED AS WE APCHED 30 MI W. AN ACFT WAS OBSERVED TO BE IN A DSCNT FROM THE SAME ALT AS OURSELVES. WE THEN REVIEWED ALL OF THE WAYPOINTS IN THE FLT PLAN. WE NOTICED THAT OUR WAYPOINT (5130) HAD A LATITUDE/LONGITUDE OF N 50.00.0 W 30.00.0. AS A RESULT OF AN INPUT ERROR, WE FLEW AN INCORRECT RTE. THE TCASII TA AND RA WAS A RESULT OF THIS NAV ERROR.
