Hi guysHow can I make xml gauge compatible this line(A:ENG1 TORQUE, ft-lbs) * (A:General eng1 rpm,RPM) / 5252ThanksBenjamin

Do you mean how to do this calculation in an xml gauge?Xml gauges use reverse polish notation (RPN) for calculations.They are stack based and first load the calculation's variables onto a stack and then call for the calculation.Ie:A * B / C is written as A B * C /

Thanks jeroenIf i understood it well, instead of this :(A:ENG1 TORQUE, ft-lbs) * (A:General eng1 rpm,RPM) / 5252It should be this :(A:ENG1 TORQUE, ft-lbs) (A:General eng1 rpm,RPM) * 5252 /I Gonna try this outBenjamin

In case you hadn't noticed yet, there is a dedicated forum for "MSFS Aircraft and Panel Design," which includes -oddly enough- "gauges..." :( http://forum.avsim.net/forum/122-msfs-aircraft-and-panel-design-forum/
