Hi all,How can I set a default value for and XML gauge? I am programming an engine fuel valve switch in XML format, and I want that when the aircraft load in FS2002, the fuel valve is in the off position.I have attempted it with the following code but it doesn't work:(A: GENERAL ENG1 FUEL VALVE,bool) 0 ==(A:GENERAL ENG1 FUEL VALVE,bool)Thank you for your help.greetingsRafael

Rafael, A simple way is to use a (G:Var) which are always reset to zero on initial gauge load, once the gauge loads it will check the value of the fuel selector and if necessary turn it off and toggle G:Var to 1.(G:Var1) 0 == if{ 1 (>G:Var1) + (A:GENERAL ENG1 FUEL VALVE, bool) 1 == if{ (>K:TOGGLE_FUEL_VALVE_ENG1) } }Hope this helps. Regards,RomanProject 737-400Note, the way it looks here on the forum is different since HTML has processed it. On paper the " < " would be " & l t ; " , the " > " would be " & g t ; " and the " & " would be " & a m p ; ". All without the quotes and remove spaces between characters.

Hi RomanThank you very much for your help. Your code works fine. My idea is creating a panel that load in a "cold and dark cockpit". Any others ideas?Again, thank you for your help.greetingsRafael

>Hi Roman >>Thank you very much for your help. Your code works fine. My >idea is creating a panel that load in a "cold and dark >cockpit". Any others ideas? Ha! A person after my own heart... I too have been developing that concept with my little Socata TB20GT project. I want the simmer to step into a totally 'cold and dark cockpit,' and have to follow the real life startup procedures, beginning with finding the cockpit "courtesy light switch" (assuming that it's a night flight, of course!). The courtesy light is the only device in the a/c that bypasses the master battery switch, and is on a timer circuit to prevent battery drain should someone forget to turn it off manually... :)
