Unformatted text preview: W-Wt/Bal Terms Match the definitions in the second column with the term in the first column 1. Arm is the horizontal distance in inches from the reference datum line to the center of gravity of an item. A - Datum (reference datum) x 2. Standard empty weight includes the standard empty weight plus optional and special equipment that has been installed. B - Moment index (or index) x 3. Center of Gravity is the point about which an airplane would balance if it were possible to suspend it at that point. C - Standard empty weight ( GAMA ) 4. Datum is an imaginary vertical plane or line from which all measurements of arm are taken. D - Arm ( moment arm) x 5. Moment is the product of the weight of an item multiplied by its arm. E - Payload ( GAMA ) x 6. Station is a moment divided by a constant such as 100, 1,000, or 10,000. The purpose of using this is to simplify weight and balance computations of airplanes where heavy items and long arms result in large, unmanageable numbers.arms result in large, unmanageable numbers....
