Flight mass is the sum of empty mass, cockpit load, baggage and water ballast. Flight mass c.g. calculation<br />

is done in a table as shown by example below:<br />

- multiply mass by distance from datum (positive for items aft of datum) to get moment [kg.mm] of<br />

each item,<br />

- add up moments of all items,<br />

- add up masses of all items,<br />

- divide the sum of moments [kg.mm] by the sum of masses [kg] to obtain flight mass c.g. [mm].<br />
