The aeroplane component would hold the id of the persistent filter that holds the indices of its weapons. in short, a filter is a way to subset groups using double array indexing.

A group is a set of entities and the components are stored in linear arrays
a filter is an array of indices of these component arrays, so a way to subset the component arrays.
the subset is defined as
componentArray[filterArray[i]]
