When should weight and balance calculations be conducted?

Weight and balance calculations should be conducted prior to every flight to ensure the aircraft is within its safe operating limits. This practice is crucial for aircraft safety and performance, as it influences how the aircraft will handle in flight, including its stability and controllability. Properly calculating weight and balance helps to determine the center of gravity, which affects the aerodynamic characteristics of the aircraft.

Conducting these calculations before each flight allows pilots to account for variations such as changes in passenger load, cargo weight, and fuel levels, which can all impact the aircraft’s total weight and balance. Regular checks help prevent overloading, which can lead to diminished performance and an increased risk of accidents.

Performing these calculations only before long flights, during maintenance, or just for new aircraft does not account for the dynamic nature of flying, where conditions can change significantly even between flights. Thus, regular weight and balance assessments are a critical part of pre-flight checks for aviation safety.
