What is the maximum allowable cargo load (ACL) of a C-17 aircraft?

The maximum allowable cargo load (ACL) of a C-17 aircraft is 170,900 pounds. However, if you are required to choose from the provided options, then an answer reflecting a common misconception in approximating the aircraft's capabilities arises.

The choice of 140,000 pounds is often referenced as it might be a figure used within certain contexts or operational guidelines; however, it does not reflect the full capacity of the C-17. Fundamental to understanding aircraft capacities is recognizing the distinctions among maximum useful loads, operational limits, and specific mission configurations.

It's essential to rely on current and verified military transport documentation when assessing aircraft load capabilities, as they ensure accuracy in mission planning and safety in operations. The other options represent higher or lower weights that do not align with standard operational guidelines for the C-17.
