We have decided that hardcoded initialization of instruments and systems is bad. So we remove them. Hardcoded initialization is bad because it can't be overridden from config files or from the command line. We prefer to do it through config files that should be, eventually, aircraft specific (*-set.xml), not global (preferences.xml).
