Out of the box, the PMDG 737 NGX doesn’t come with a fuel planner. You can manage many options, weight and balance from within the FMC but if you don’t have a flight planning tool or other fuel consumption reference handy, you may need this.
It’s a freeware fuel planner, for the PMDG 737-800 NGX. Thanks to Frederic FURST.
March 6th : new version see the updated link above.
