Does anyone know how this A var is adjusted and how it is engaged?ThanksMitch

Hi Mitch,As far as I know (please correct me when I'm wrong) MS didn't support RPM hold with the AT (at least not in FS2004). The named parameter belie it does but there's no command to activate RPM hold.Some months ago I made a N1 and EGT hold for my ARJ panel. But this was just realized with tricks (continously scanning of the current N1 an comparing it with the desired N1 - then increasing or decreasing thrust using Throttle_Set in big or small steps depending of the difference). It works but it's far away from beeing perfect.Hope the next FS version will support a command for it.Best RegardsMatthias

Thanks Matthias, I thought that might be the case, but had to ask.Mitch
