Hi everyone, maybe is an old subject but I'd like to publish what I've found anyway...the bug of the ATR autopilot going 10 by 10 is related to the following gauges: FSC.ATR72500!proprpm1 -FSC.ATR72500!proprpm2 and FSC.ATR.ap!Autopilot controls . So I eliminated these gauges and substituted with others similars from any turbo propellers planes gauges...and it works fine !
get in touch with me if you have this problem !! stay cool & loose Flatom flaviogioia@hotmail.com
