For YASim we have to fake the external forces with the thruster. A thruster in YASim is a very simple "thrust only" engine object which not consume any fuel etc.

For the coordinates use the same like the ccordinates of the Nosegear. The thrust itself is in lbs- don't set it too high! 1/3 of the of the aircraft's empty mass should be enough!

Then we just have to add our [[Menubar|menu]] dialog. A generic one is available at <tt>$FG_ROOT/gui/Dialogs/pushback.xml</tt>. Add the following lines to include it in the Equipment menu of the aircraft. Note: if the menubar and default tags are already there, you do no need to add them again. Just place the stuff between them.
