I have come across [automatic differentiation](https://en.wikipedia.org/wiki/Automatic_differentiation) which should also allow to generate a linear model with much more flexibility than what was done by `FGLinearization`. With that technique you can...

@seanmcleod There were at some point 3 different trim algorithms in JSBSim. #### Legacy trim routines These are the older (and the last still active) trim routines. They were designed...

After some more archeological unearthing, I found the following 2 discussions threads in the mailing list archives: * [Announcement of the addition of the simplex code to JSBSim](https://sourceforge.net/p/jsbsim/mailman/jsbsim-devel/thread/000001cdb26e$60f15db0$22d41910$@net) dated Oct...
