FG button not Found in simulation Tab in MP!

Hi all ,

I wanted to use flightgear to simulate my mission , I read the documentation web page ,
but it explane steps that I didn’t find in the mission planner such as ( Start FG Plane ) button
it’s not found in MP even they show it in picture in the web .



until now I couldn’t get the simulation work ,
How I can Make it work ?



Some of the topic explanation is not clear.
If you prepare video explanation for some topic , will be more useful and easy for users .

we are slowerly migrating to SITL.

the issue is that the usb port to the autopilot is not fast enough to supply the data required.

@Michael_Oborne ,

So what is the best available simulation method for plane. ?
