This tool assists in determining the center of gravity (CG) for an aircraft. A simplified example involves calculating the moment (weight multiplied by arm, the distance from a reference datum) for each item loaded onto the aircraftpassengers, baggage, fuel, etc.and summing these moments. Dividing the total moment by the total weight yields the CG location. Modern implementations often feature intuitive interfaces and detailed weight and balance reports.
Accurate CG calculations are essential for safe and efficient flight. An improperly balanced aircraft can experience reduced controllability, increased drag, and potentially catastrophic consequences like a stall or structural failure. Historically, manual calculations with charts and graphs were the standard, making the process time-consuming and prone to error. Digital tools have streamlined this critical process, increasing both speed and accuracy while minimizing risks.
