Company Policy; Human Factors; Procedure
We were filed for and received clearance to fly the SHNON 2 arrival into IAD; but were not given the fuel for the arrival that we were filed for. The arrival clearly shows that we are to cross DRUZZ at 11;000 FT and the release has us flying all the way to just before DRUZZ at FL290. Also the burn on the release from ELISN to IAD was 17 LBS of fuel burn. The SHNON 2 arrival does not go from ELSIN to IAD. There is either a turn north or south depending on which runway is active. The actual burn from ELSIN to the airport was 300 LBS not 17 LBS. The total burn on the release was 3;449 LBS and the actual burn was 4;057 LBS which meant that; if we took off with minimum fuel; we would have landed with 1;600 LBS of fuel.
ERJ170 Captain reportd the flight planning software used by his company does not consider the entire arrival route and normal delays at large busy airports.
