What should be done with tare weight when weighing an aircraft?

Tare weight refers to the weight of any equipment or materials that are not part of the final measurement but are included in the weighing process. When weighing an aircraft, it is crucial to account for tare weight to ensure an accurate representation of the aircraft's actual weight. This is achieved by subtracting the tare weight from the scale reading.

By doing this, you isolate the true weight of the aircraft, excluding any extra weight from weighing instruments or covers. Accurate weight measurements are vital because they affect aircraft performance, load calculations, and safety assessments. Correctly addressing the tare weight is essential for compliance with regulatory requirements and for operational accuracy in aviation.

This method also distinguishes between the empty weight of the aircraft (which includes all fixed equipment, unusable fuel, and other necessary components) and any external items that may be influencing the scale during the weighing process.
