Which is right,
but don't forget that we can within JSBSim avoid most of the Nasal code
everything done in the FDM.
For instance, i do use it to get the right (factor) animation with propellers,
the brake chute animated under conditions, and so on everything done
without Nasal.
Nasal animation Probably valuable for YASim but with JSBsim their is an other
way easier.
