What is the purpose of calculating 'weight and balance' in aviation?

Calculating 'weight and balance' in aviation is essential for ensuring that the aircraft is properly loaded for safe flight. This process involves assessing the total weight of the aircraft and its distribution, which directly impacts its performance, stability, and control. Proper weight and balance calculations help maintain the center of gravity within specified limits, ensuring that the aircraft can be maneuvered safely throughout all phases of flight, including takeoff, landing, and cruising.

If the aircraft is overloaded or if the weight is not distributed correctly, it may lead to difficulty in controlling the aircraft or even result in structural damage. Therefore, weight and balance calculations are crucial for the overall safety and effectiveness of any flight operation, ensuring that the aircraft can perform as intended without risking safety.

The other options, while related to aviation, do not directly address the primary purpose of weight and balance calculations, which is centered on safety and stability in flight.
