|There can be any number of pointmasses. Each can also have a shape which - if present - causes an associated moment of inertia to be calculated based on the shape. Note that a cylinder is solid, a tube is hollow, a ball is solid and a sphere is hollow. | |There can be any number of pointmasses.

* Fuel weight is defined in the [[JSBSim Propulsion|propulsion section]]. | |||
You can add the pointmasses to the Equipment > Fuel and payload dialog, by adding the following code (for each single pointmass) to your aircraft's -set.xml file: | |||
<syntaxhighlight lang="xml"> | |||
<payload> | |||
<weight> | |||
<name type="string">Passengers and crew</name> | |||
<weight-lb alias="/fdm/jsbsim/inertia/pointmass-weight-lbs[0]"/> | |||
<min-lb type="double">3000.0</min-lb> | |||
<max-lb type="double">90000.0</max-lb> | |||
</weight> | |||
