Child elements

NameTypeConstraintsOccurrenceHow often the element may appear at this place. The schema writes it as minOccurs and maxOccurs on the declaration.DefaultDescription
allThe children below may appear in any order. Each may appear at most once.
areadoubleBaseType[0..1] optionalReference area (typically planform area)
lengthdoubleBaseType[0..1] optionalReference length (typically Mean Aerodynamic Chord MAC). In CPACS, only one reference length exists (and is used, e.g. for all three moment coefficients. Coordinates given relative to MAC shall always use this length as MAC.
pointpointType[0..1] optionalMoment reference point (in global coordinate system). The x-coordinate is typically chosen same as of the leading edge of the wing in the spanwise section having a chordlength identical to MAC. Coordinates given as %MAC shall always use this x-coordinate and length (e.g. 0%MAC = x, 100%MAC = x + length). The y coordinate is typically 0. The z coordinate is often chosen either as 0., or as z of fueselage nose or as z of middle of center fuselage part.
