Narrative:
We were flying to iad and were filed to fly the shnon 2 RNAV arrival into iad. While at the gate; the first officer put the flight plan into the FMS and I doublechked that it looked right. When I looked over what was in the FMS at the gate everything appeared to be right. The shnon 2 arrival is supposed to be flown hvq-dilnn-puttz-finks-doccs-ldn-shnon-royil-kewpy-elsin. When we crossed hvq; I noticed that the plane was heading to shnon instead of dilnn. As soon as I noticed (pretty much right over top of hvq); I had the first officer ask ATC what they showed us doing after hvq. ATC replied that they showed us filed for the shnon 2 arrival after hvq. We advised them that somehow we had hvq-shnon and that we would fly the arrival. At that point ATC gave us a clearance of direct dilnn then join the shnon 2. We continued the flight and landed at iad without further incident. I believe the event happened because I might have seen what I wanted to see in the FMS while we were at the gate. Contributing factors were the fact that it seems like the shnon 2 arrival is pre-loaded into the FMS wrong. When my first officer tried to put the shnon 2 arrival into the FMS when we were over the top of hvq (using the navigation-arrival-STAR feature of the FMS); it still went straight from hvq to shnon instead of hvq to dilnn. So I had the first officer put the fixes in the FMS manually. Other contributing factors include: 2 MEL's that were on the plane which was the pack 1 and the autoplt were deferred. The cockpit stayed at about 28 degrees C most of the day and the combination of being hot while hand flying in bad WX and an early report time for work ended up taking a toll on my mind. Also while we were fueling the right wing took more fuel than the left wing did for a while which set off the fuel imbal EICAS message. The fuel system then corrected itself before the fueler was done fueling. With those distrs and the delays; it seems like I was able to overlook a mistake in the FMS routing.

Title: NEAR TRACK DEV OCCURS AFTER E145 FLT CREW -- INCORRECTLY -- MANUALLY INSERTS WAYPOINTS OF SHNON RNAV STAR TO IAD IN THE FMS ROUTE.
Narrative: WE WERE FLYING TO IAD AND WERE FILED TO FLY THE SHNON 2 RNAV ARR INTO IAD. WHILE AT THE GATE; THE FO PUT THE FLT PLAN INTO THE FMS AND I DOUBLECHKED THAT IT LOOKED RIGHT. WHEN I LOOKED OVER WHAT WAS IN THE FMS AT THE GATE EVERYTHING APPEARED TO BE RIGHT. THE SHNON 2 ARR IS SUPPOSED TO BE FLOWN HVQ-DILNN-PUTTZ-FINKS-DOCCS-LDN-SHNON-ROYIL-KEWPY-ELSIN. WHEN WE CROSSED HVQ; I NOTICED THAT THE PLANE WAS HEADING TO SHNON INSTEAD OF DILNN. AS SOON AS I NOTICED (PRETTY MUCH RIGHT OVER TOP OF HVQ); I HAD THE FO ASK ATC WHAT THEY SHOWED US DOING AFTER HVQ. ATC REPLIED THAT THEY SHOWED US FILED FOR THE SHNON 2 ARR AFTER HVQ. WE ADVISED THEM THAT SOMEHOW WE HAD HVQ-SHNON AND THAT WE WOULD FLY THE ARR. AT THAT POINT ATC GAVE US A CLRNC OF DIRECT DILNN THEN JOIN THE SHNON 2. WE CONTINUED THE FLT AND LANDED AT IAD WITHOUT FURTHER INCIDENT. I BELIEVE THE EVENT HAPPENED BECAUSE I MIGHT HAVE SEEN WHAT I WANTED TO SEE IN THE FMS WHILE WE WERE AT THE GATE. CONTRIBUTING FACTORS WERE THE FACT THAT IT SEEMS LIKE THE SHNON 2 ARR IS PRE-LOADED INTO THE FMS WRONG. WHEN MY FO TRIED TO PUT THE SHNON 2 ARR INTO THE FMS WHEN WE WERE OVER THE TOP OF HVQ (USING THE NAV-ARR-STAR FEATURE OF THE FMS); IT STILL WENT STRAIGHT FROM HVQ TO SHNON INSTEAD OF HVQ TO DILNN. SO I HAD THE FO PUT THE FIXES IN THE FMS MANUALLY. OTHER CONTRIBUTING FACTORS INCLUDE: 2 MEL'S THAT WERE ON THE PLANE WHICH WAS THE PACK 1 AND THE AUTOPLT WERE DEFERRED. THE COCKPIT STAYED AT ABOUT 28 DEGS C MOST OF THE DAY AND THE COMBINATION OF BEING HOT WHILE HAND FLYING IN BAD WX AND AN EARLY RPT TIME FOR WORK ENDED UP TAKING A TOLL ON MY MIND. ALSO WHILE WE WERE FUELING THE R WING TOOK MORE FUEL THAN THE L WING DID FOR A WHILE WHICH SET OFF THE FUEL IMBAL EICAS MESSAGE. THE FUEL SYS THEN CORRECTED ITSELF BEFORE THE FUELER WAS DONE FUELING. WITH THOSE DISTRS AND THE DELAYS; IT SEEMS LIKE I WAS ABLE TO OVERLOOK A MISTAKE IN THE FMS ROUTING.
