With Fuel Burn confirmed, I took the opportunity to create a spreadsheet with already made formula for each aircraft based off their respective fuel burn ratio (linked here) so you can calculate how much fuel you will need for your flight. The only figures you will have to change to complete sum is the value in the distance of your flight and how much emergency fuel/taxi fuel you want (based off miles). This spreadsheet is for all to use. All the work in this spread sheet was painstakingly done with data provided by aircraft manufacturers of fuel capacity and max range for said aircraft. I can confirm that these values are accurate and translate into IF. The only time they will not are if you are flying outside an aircraft’s operational range and/or there are some inaccuracies with the MTOW or Fuel capacity in IF.
