Weight and balance determines whether the center of gravity is within the approved limits. A CG that is too far forward or too far aft can affect handling, stability and safety.
TrimCalc can add weights and also remove weights from the calculation, for example when equipment is not installed. A QR code can be generated for each aircraft profile and placed directly on the aircraft.
