What is the purpose of the 'Qty' column in the Weight and Balance chart?

The 'Qty' column in the Weight and Balance chart serves to show the number of each item on board an aircraft. This is essential for calculating the total weight of the aircraft, as the total weight is determined by multiplying the quantity of each item by its individual weight. Understanding the quantity of specific items helps flight engineers and operators manage the aircraft's loading procedure effectively, ensuring that the aircraft remains within its weight limits for safe operations.

This quantification is crucial for accurate weight and balance calculations, which directly affect the aircraft's performance, stability, and safety during flight operations.
