Fuel Weight given Takeoff Weight Solution

Follow our step by step solution on how to calculate Fuel Weight given Takeoff Weight?

FIRST Step Consider the formula
FW=DTW-OEW-PYL-Wc
Next Step Substitute values of Variables
∴ FW=250000kg-125000kg-12400kg-12600kg
Next Step Prepare to Evaluate
∴ FW=250000-125000-12400-12600
LAST Step Evaluate
∴FW=100000kg
