@jonsberndt can you shed any light on what the problems were in the code when you removed it via commit https://github.com/JSBSim-Team/jsbsim/commit/0c739604464f0f3eaceda676d200f33c89b20180? In particular I guess if you remember any particular...

@rega0051 what additional control of the trim options are you looking for? In terms of freeplay, deadband etc. if you don't want them included while generated the linearized model are...

@agodemar I'm trying to remember/figure out the relationship between your paper - **'A General Solution to the Aircraft Trim Problem'** - http://wpage.unina.it/agodemar/DSV-DQV/AIAA-2007-6703-905_DeMarco_Duke_Berndt.pdf and the trim code you mention in the...

@bcoconni thanks for the good summary. I'm interested in trim routines that can potentially handle more cases than the current trim routines in JSBSim so I'll spend some time in...

When I was searching yesterday I also came across a couple of YouTube videos he posted demonstrating the trim functionality via a GUI he produced and also generating linearized models...

Here is a potentially useful paper (I haven't paid the $25 to download it) - [Modelling and Analysis of Turbofan Engines Under Windmilling Conditions](https://arc.aiaa.org/doi/10.2514/1.B34729) I'm not suggesting that we implement...

Or if we could get hold of the DFDR data from the B767 Gimli Glider or A330 Azores Glider we could take a look at their N1/N2 windmilling values as...

While looking into something else I came across this table. Now if you look at the qbar values in the table and the fact that under windmilling conditions `N1 =...

@Octal450 @bcoconni I've recreated the table above and added in a column to show the ram airflow as suggested by @bcoconni. `double AirFlow = in.Density * in.AeroUVW(eU);` And then shown...

So looking at the left edge of the windmill regime, i.e. line passing through points (M0.3, 0m), (M0.4, 4000m), (M0.5, 8000m).  Now I thought it might turn out the...
