There is no default key/button binding for a trigger in FlightGear, so you will have to make your own. An obvious choice of button would be the trigger on a [[joystick]], but you can also make a keyboard binding by adding something like this to your <tt>[[$FG ROOT]]/keyboard.xml</tt> file: | There is no default key/button binding for a trigger in FlightGear, so you will have to make your own.
