massBreakdownType

1. General

The <massBreakdown> is subdivided in <designMasses>, <fuel>, <payload> and <mOEM> (operating empty mass).

designMass

The design masses contain the overall values for mTOM and so forth. These should be listed as specified by the TLAR or found from initial sizing.

fuel and payload

The fuel and payload nodes should contain maximum values, i.e. full fuel tanks, all passengers on board and full cargo holding. These values may exceed the maximum allowable take-off mass as the actual loading of the aircraft should be specified in the weight and balance section of the aircraft.

mOEM

The operation empty mass structure is based on the Airbus Mass Standard brake down [AIRBUS MASS STANDARD 2008]. The operator’s mass empty (OME) is defined by the sum of the following component masses:

operator’s items
manufacturer’s mass empty (MME)

2. massDescription

Each sub component has the following <massDescription> which include a:

Name
Description
parentUID
Mass value
Mass location
Mass orientation
Mass Inertia.

The <massDescription> can be found at the <designMasses> direct under each item. At the <fuel>, <payload> and <mOEM> under massDescription in each item and sub item.

Concerning symmetry, a reference to a symmetric component (e.g. a wing) accounts for both components created by the symmetry, i.e. for the defined and the mirrored side, so their total mass has to be given. If the masses of the two sides differ, they are given separately, and the @symmetry attribute of the reference selects the side (def or symm, see stringUIDBaseType).
