Desired Take off Weight Solution

Follow our step by step solution on how to calculate Desired Take off Weight?

FIRST Step Consider the formula
D=PYL+OEW+FW
Next Step Substitute values of Variables
∴ D=25t+10t+1.1t
Next Step Prepare to Evaluate
∴ D=25+10+1.1
Next Step Evaluate
∴D=36100kg
LAST Step Convert to Output's Unit
∴D=36.1t
