The Dry Operating Mass (DOM) is a critical concept in mass and balance calculations for aircraft. It specifically represents the mass of the aircraft without any fuel onboard. This figure includes the aircraft's empty weight along with necessary operational items, such as crew, baggage, water, and any other equipment required for the aircraft to be operable but excludes the weight of the fuel.

Understanding the DOM is essential for pilots and operators because it forms the basis for calculating the aircraft's total weight at takeoff when the fuel weight is added. This information helps ensure that the aircraft's weight remains within safe operational limits, allowing for proper performance calculations during flight.
