Auto Throttle - ATR72 Turbo Prop?

I know this goes against the whole realism aspect of things however, I would like to add an Autothrotle to an ATR72 . What, if any, changes can be made to the cfg to enable this aircraft to have A/T.I'm sure I read something years ago regarding adding a A/T function onto props but I've not pulled anything up on a "search"below is a copy of the aircraft.cfg[fltsim.0]title=ATR72-500 Aurignysim=atr72 500model=panel=sound=texture=aurchecklists=kb_checklists=atr72_500_checkkb_reference=ATR72_500_refdescription=ATR72-500 Beta 1 n© 2001-2002 Francisco S
