What is the term used for the calculation of an aircraft's total weight before departure?

The term used for the calculation of an aircraft's total weight before departure is referred to as a pre-flight weight and balance check. This process is essential in aviation, as it helps ensure that the aircraft is operating within its weight limits, which is critical for safe flight operation.

During this check, all weight components are taken into account, including the aircraft's empty weight, cargo, passengers, and fuel. By calculating the total weight and confirming the center of gravity remains within the acceptable range, flight crews can anticipate the aircraft's performance, stability, and control characteristics during flight.

Other terms listed do not accurately describe the comprehensive process of assessing weight along with balance as done in a pre-flight weight and balance check. While "takeoff weight check" might suggest a focus on weight at the moment of taking off, it lacks the thoroughness of preliminary assessments and adjustments in weight distribution. "Final weight analysis" and "aircraft weight audit" suggest evaluations that might occur post-flight or in a different context, not specifically addressing the pre-flight requirements necessary for safe aircraft operation.
