Enter the planned fuel burn, max allowable landing weight, zero fuel weight, and fuel already on board to calculate the maximum fuel uplift.

Fuel Uplift Formula

The following equation is used to calculate the maximum Fuel Uplift.


  • Where MFUL is the maximum fuel uplift (kg)
  • FPFP is the flight planned fuel burn (kg)
  • MALW is the maximum allowable landing weight (kg)
  • ZFW is the zero fuel weight (kg)
  • FAOB is the fuel weight already on board (kg)

To calculate the fuel uplift, add together the flight planned fuel burn and maximum allowable landing weight, then subtract the zero fuel weight and, fuel weight already on board.

What is a Fuel Uplift?


A fuel uplift, or maximum fuel uplift, is a measure of the total weight of fuel provided by a fuel supplier to an aircraft.

How to Calculate Fuel Uplift?

Example Problem:

The following example outlines the steps and information needed to calculate Fuel Uplift.

First, determine the flight planned fuel burn. In this case, the planned burn is 110,000 lbs.

Next, determine the maximum allowable landing weight. This is determined to be 310,000. lbs.

Next, determine the zero fuel weight. This is found to be 240,000 lbs.

Next, determine the fuel already on board. In this example, there is only 25,000 kg on board.

Finally, calculate the maximum fuel uplift.


MFUL = (110000+310000) – 240000 – 25000

MFUL = 155,000 lbs
