There are lots and lots of possible animations to be made with model.cfg, but for correct implementation of things like cockpit gauges it lacks certain animation sources.
Right now, you can only "fake" several gauges with animation sources like "rpm" or "speed", but several new ones like "engineOn"/"engineOff" would help with creating better animations to improve player immersion.
Possible new animation sources:
engineOn - detects if engine is on
engineOff - detects if engine is off
temperature - detects engine temperature
oil - this one actually already exists, but its not functioning in A3
