Quick start:
a320fuelcalc.html or a332Ffuelcalc.html in the root directory are completely integrated html files. So you don't have to mess around with additional css and js files. Currently this htmls are to be used for the FGFS IDX-A32x Airbus A320 or A330(-200F). Copy the html to a local folder or to a (offline) webserver and open it with any browser.
