Hello, While not to do with panel design i would like some help if possible, I am using a panel in an aircraft which is not for this particular plane, everything works ok except for the throttle switch ,ie i would like to be able to set the speed on the autopilot, at the moment it lights up but will not hold it, is there anything i can change in the panel CFG file to fix it, Thanks,

I don't know which AP gauge you are using, or which plane, but check this:In the aircraft.cfg, check the value of (Autopilot section):autothrottle_arming_required=If it's 1, your AP gauge needs to have an AutoThrottle switch that needs to be set BEFORE you can activate Airspeed/Mach Hold.Rob

Hi Rob, Thanks for the help, Cheers.
