Fuel Burn Calculations

Fuel burn Calculations for FltPlan.com users on the internet are now available.

Fuel burn calculations are now available on FltPlan.com's internet flight planning program.

Here are some of the important considerations.

  • Due to liability concerns, you will have to enter your own fuel burn numbers. FltPlan.com will NOT provide default fuel flow numbers due to the wide range of aircraft and pilots that use this website.

  • If you are new to FltPlan.com, we recommend you skip fuel burns for now and get more familiar with the program.

  • It will take time and energy to get the numbers right. You will have to use a combination of writing some fuel flow numbers down while flying, along with using your flight manual. (it's not that hard, really!)

  • Bad data in, will give you bad data out.
    Translation: the more accurate the numbers you enter, the more accurate your fuel totals will be on the NavLog. If your enroute times on the NavLog have been accurate, then you're ready for Fuel Burn Calculations. If your enroute times have been off, then you should check the accuracy of your climb, rate of climb, cruise and descent speeds first.(by using the Custom Aircraft page)

  • We recommend that you make a printout of the Custom Aircraft performance page and bring it on your next trip to write the numbers down that you'll need. When you get back from your trip, just enter them in.

  • The FltPlan.com staff is available to assist you with questions you might have.
    If you are a new user to FltPlan.com, we will ask you to please use the program for a while before tackling Fuel burns.
    To our regular users...ask away.



    Some of the parameters you will need to provide are:
  • Typical Taxi Fuel Burn used from engine start to take-off (Taxi Fuel).
  • Climb (not T.O.) Fuel Flow per hour (pounds or gallons) at 2,000 MSL.
  • Climb fuel Flow at Max. Altitude for your aircraft.
  • Descent fuel Flow at Max Altitude.
  • Descent fuel Flow at 2,000 MSL (clean configuration).
  • Cruise fuel Flow, at Mid/High weight (@ ISA), throughout the operating altitudes of the aircraft.
    These numbers will then be entered on the Custom Aircraft section of the program.
    After entering these numbers in Custom Aircraft , calculations will be performed on each leg you fly and fuel burn totals for various altitudes and burn between legs will be provided on the NavLog to take with you on your flight.
