I think you may be looking at an out-of-date version of
the getstart manual.

A while ago I went through and re-documented the command-line
options. for the --fdm option, we now have the following text:

"Select the core flight model. Options are jsb, larcsim, yasim,
magic, balloon, external, pipe, ada, null. This option can normally 
be ignored, as the -aircraft option will set the FDM correctly."

I think that is sufficient for most users.
