Hi Gang,I have installed a CPT toggles autothrottle switch in a panel and now the engine gauges rev up and down repeatedly at airspeeds below roughly 200 Knots. I have used default Kingair engine gauges. Above 200 knots the gauges settle down and work ok.Any ideas?

I think the author reported difficulty in matching the XML autothrottle switch function to equal that of the King Air (or was it the feathering switch?). You should search this board for a discussion of the problems he had. It may be that the necessary paramters are not exposed to XML for one or the other of these switches.Steve

Hi Steve,Thanks for the reply. I may have glossed over the info you mention. I still have the zip file for the toggles and switches, so I will check the readme.
