"Weight and balance" in aviation primarily refers to the calculation ensuring the aircraft is loaded within its weight limits for safe operations. This concept is essential for several reasons. Proper weight distribution affects the aircraft's center of gravity, which plays a crucial role in flight stability and control. If an aircraft is overloaded or improperly balanced, it could lead to degraded performance, reduced safety margins, and potential loss of control during flight.

When calculating weight and balance, pilots must consider the total weight of the aircraft, including the weight of passengers, cargo, and fuel. These calculations are vital to ensure that the aircraft operates within the specified weight limits outlined in the aircraft's operating handbook, as exceeding these limits can lead to various operational issues.

While the other choices touch on aspects of aircraft operation—such as structure, system configuration, and the weight of cargo—they do not encompass the full scope of "weight and balance" as it relates specifically to the critical calculations that ensure the aircraft's safe handling and performance during flight.
