I want to perform a run once check when an aircraft loads to make sure that, if the engine is not running when the aircraft is loaded, the fuel valve is set to the off position, ready for a start sequence. problem is , the run once check is not performed until, after I start from a saved flight, I have to reload the aircraft to make the gauge recognise it needs to turn the fuel valve off. This is a real pain. Anyone know why it wont work just from a saved flight and not also having to reload aircraft?(A:General eng fuel valve:1,bool) (L:foff,bool) 0 == (A:ENG1 COMBUSTION,bool) 0 == && if{ 1 (>K:TOGGLE_FUEL_VALVE_ENG1) 1 (>L:foff,bool) } 1 (>K:TOGGLE_FUEL_VALVE_ENG1) Steve

Hi Steve,Strange, should work.Tried this one?(G:Var1) 0 == if{ (A:ENG1 COMBUSTION,bool) ! if{ (>K:TOGGLE_FUEL_VALVE_ENG1) } 1 (>G:Var1) } Jan"Beatus ille qui procul negotiis..."
