Adding a existing component to an existing aircraft

On march 25, 2020 I was asked via mumble, if I could add the garmin196 to the Seneca II, hence the AP is not charming. Here ist what I did, an how I did it.

Creating a working copy of the aircraft

At first I aquired the Aircraft. It's part of the sourceforge/svn-repository.

I got the plane searching throught FGADDON/AIRCRAFT (https://sourceforge.net/p/flightgear/fgaddon/HEAD/tree/trunk/Aircraft/) using the SVN system.

   $ svn checkout https://svn.code.sf.net/p/flightgear/fgaddon/trunk/Aircraft/SenecaII

note: sourceforge does not support the correct svn-codeline, you need to correct the path starting after trunk'

Locating the system to add

I went into my system's Flightgear root directory $FG_ROOT - which is nice to know. On ubuntu and DeBIAN systems it is likely to be found in:
/usr/share/games/flightgear
  $ cd /usr/share/games/flightgear/

Hence I looked for garmin196 invoking a full recursive file-search

 me@machine:/usr/share/games/flightgear/$ ls -R | grep -A1 -i garmin196

and I figured that the device's files are located in /Aircraft/Instrument-3d/garmin196

Understanding the components of the system

Adding the model to the aircraft, positioning
