replies Jon and Hal.
Ron Jensen has patiently tried coaching me with jsbsim , but I'm a
slow learner ;)

It's not automatic - not a natural effect calculated by JSBSim code itself.
Like many things in JSBSim, the facilities are present to let the aircraft

Does jsbsim ? I've just begun to look into it , so I don't really know
jsbsim's capabilities.

Ok, i worded that wrong ... action point is a way to specify the
thrust point if it's not the point defined for the engine mass ... and
yes , the coordinates are relative the aircraft origin ... my mistake.

My more simple understanding was the actionpoint was the point where
thrust was applied relative to the engine mass , like the
documentation states.
an subelement

Thank you Emilian and Buck
Ok i tested changing the location of the point to ahead of the engine
and also behind the engine, near exhaust.
Irrespective of the location, looking at the results at the Yasim
solver, i do not see much impact.
Surprisingly i do not see any change to Drag Coef or
