Enter the total aircraft lift (N) and the total aircraft weight (N) into the Load Factor Calculator. The calculator will evaluate the Load Factor. 

Aviation Load Factor Formula

The following two example problems outline the steps and information needed to calculate the Load Factor.

LF = L / W


  • LF is the Load Factor ( )
  • L is the total aircraft lift (N) 
  • W is the total aircraft weight (N) 

To calculate the aviation load factor, divide the aircraft lift by the aircraft weight.

How to Calculate Aviation Load Factor?

The following steps outline how to calculate the Load Factor.

  1. First, determine the total aircraft lift (N). 
  2. Next, determine the total aircraft weight (N). 
  3. Next, gather the formula from above = LF = L / W.
  4. Finally, calculate the Load Factor.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total aircraft lift (N) = 5000

total aircraft weight 9N) = 3000

LF = L / W = ?
