How is an aircraft's weight distribution checked before a flight?

An aircraft's weight distribution is primarily checked by calculating the center of gravity. This process involves assessing the weight of the aircraft as a whole, including its structure, passengers, cargo, and fuel, and determining how this weight is distributed throughout the aircraft. The center of gravity is a vital factor in ensuring proper balance and flight performance. If the center of gravity is located outside the recommended limits, it can adversely affect the aircraft's handling characteristics and safety.

Calculating the center of gravity requires accurate measurements of the weights and their respective positions within the aircraft. This calculation helps pilots and crew ensure that the aircraft remains within its operational parameters for stability and control during takeoff, flight, and landing. Proper weight distribution enhances the aircraft's handling characteristics and ensures safer operations.

In contrast, while analyzing fuel levels, weighing passengers and baggage, or performing visual inspections contribute to overall safety checks, they do not provide the complete picture of weight distribution critical for flight readiness.
