4) The function now being called turns off the magnetos. This is clearly not desired behavior if all I'm trying to do is relocate. This is a low-priority bug, because I can work around it by saving and restoring the magneto settings. | 4) The function now being called turns off the magnetos.

5) The function now being called zeros the settings for aileron trim, elevator trim, and rudder trim. Again, this is clearly not desired behavior. <ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg20095.html |title= location-in-air| | 5) The function now being called zeros the settings for aileron trim, elevator trim, and rudder trim.

I have a pretty-much workable workaround for the worstof these bugs. | |||
The big clue is that "presets-commit" apparently just deletes the old FDM instance and creates another. | |||
To make the new FDM happy, I had to delete a bunch of nodes from the property tree. Some other nodes needed to be set to -9999; merely deleting them | |||
was not good enough. This allows me to relocate-in-air once without getting flipped upside down (or worse). | |||
There is still some opportunity for improvement in connection with presets-commit and with FDM init in general.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg20095.html |title= location-in-air| | |||

{{cquote|Once the users intentions have been communicated to the FDM module, it's really up to the particular FDM, (JSBsim or YAsim) to do the right thing with the provide information.

{{cquote|Note, it appears (as best as I can see) that in air startups are broke and probably haven't worked for a while with JSBSim and YASim.
