Narrative:
While flying on the SID out of san jose we were on course towards linden VOR. We were cleared direct (RNAV) to a VOR 2 legs down on our flight plan. We were cruising at FL270. The captain engaged the omega to the autoplt and the aircraft began a right turn further than anticipated. The omega was disconnected and the navigation point being flown to was rechked. We discovered an error in the latitude/longs entered for the navigation point. Prior to this the captain flew the aircraft to heading that we considered close to a direct heading to the navigation point. We then entered the correct coordinates for the navigation point and reengaged the omega to the autoplt. The aircraft again began a turn to heading we considered inaccurate. The captain disconnected the omega and we again rechked the navigation point coordinates. We discovered the correction had not been accepted by the omega. At this time we advised ATC of navigational problem and ATC provided a vector. Additionally, I had noticed a target on the TCAS scope moving toward us. This target triggered a TA and then an RA which told us to descend. I do not recall us taking any action mainly because we had visually picked up the aircraft coalt with us and opposite direction however, it was passing 4-5 NM to the south of us. After the RA, ATC asked us if we had the traffic in sight and we acknowledged we did.

Title: ACR MLG TRACK HDG DEV USING RNAV WITH ACFT COUPLED TO OMEGA. THE WRONG LAT HAD BEEN INSERTED AND NOT VERIFIED BY THE OTHER CREW MEMBER.
Narrative: WHILE FLYING ON THE SID OUT OF SAN JOSE WE WERE ON COURSE TOWARDS LINDEN VOR. WE WERE CLRED DIRECT (RNAV) TO A VOR 2 LEGS DOWN ON OUR FLT PLAN. WE WERE CRUISING AT FL270. THE CAPT ENGAGED THE OMEGA TO THE AUTOPLT AND THE ACFT BEGAN A R TURN FURTHER THAN ANTICIPATED. THE OMEGA WAS DISCONNECTED AND THE NAV POINT BEING FLOWN TO WAS RECHKED. WE DISCOVERED AN ERROR IN THE LAT/LONGS ENTERED FOR THE NAV POINT. PRIOR TO THIS THE CAPT FLEW THE ACFT TO HDG THAT WE CONSIDERED CLOSE TO A DIRECT HDG TO THE NAV POINT. WE THEN ENTERED THE CORRECT COORDINATES FOR THE NAV POINT AND REENGAGED THE OMEGA TO THE AUTOPLT. THE ACFT AGAIN BEGAN A TURN TO HDG WE CONSIDERED INACCURATE. THE CAPT DISCONNECTED THE OMEGA AND WE AGAIN RECHKED THE NAV POINT COORDINATES. WE DISCOVERED THE CORRECTION HAD NOT BEEN ACCEPTED BY THE OMEGA. AT THIS TIME WE ADVISED ATC OF NAVIGATIONAL PROBLEM AND ATC PROVIDED A VECTOR. ADDITIONALLY, I HAD NOTICED A TARGET ON THE TCAS SCOPE MOVING TOWARD US. THIS TARGET TRIGGERED A TA AND THEN AN RA WHICH TOLD US TO DSND. I DO NOT RECALL US TAKING ANY ACTION MAINLY BECAUSE WE HAD VISUALLY PICKED UP THE ACFT COALT WITH US AND OPPOSITE DIRECTION HOWEVER, IT WAS PASSING 4-5 NM TO THE S OF US. AFTER THE RA, ATC ASKED US IF WE HAD THE TFC IN SIGHT AND WE ACKNOWLEDGED WE DID.
