Have a look at Professional Flight Planner X (http://www.pfpx.com/), which looks to be coming out later this year. It's made by the developers of TOPCAT. You'll be able to calculate a complete flightplan including fuel requirements based on the realworld aircraft data, forecast GRIB winds, ETOPS, redispatch, NOTAMs, etc.

That is just one perfect product! I will not fly with out TOPCAT, and now they are doing this!! Wow! Navigraph and TOPCAT are really professional utilities that makes this hobby almost seem like the real deal!

Hi, Have a look there :http://fuel.aerotexas.com/ "FUELPLAN² estimates fuel requirements and generates realistic loadsheets for selected aircraft. Enter the origin and destination ICAO codes, select your aircraft and press Calculate." Regards, Richard Portier

Shane, great info thanks. For now until PFPX comes out I am doing what Ryan does. After loading my fp, I go to the prog page and subtract my current (full) load from my fmc predicted destination fuel and add 5k for reserves. Now if flying east to west in the US, I add 2 to 3k more for winds. Works pretty good for now.
