Hi Jon,

Yes i know,

The configuration jsbsim used with FG , does not work , i could not identify 
the cause.
However when i am using the similar feature within FG , which i guess, trigger  
jsbsim , it does work.
That feature is done by an embedded  Nasal script ( there is not any exposed 
property about it ), which is probably useful with YASim. Thus that process is 
hidden.

The jsbsim FDM which  work stand alone,  with the property you refer to, don't 
with FG.
To me, any stand alone FDM jsbsim should work FG. which is not the case.
 
You may look at that "ugly"FG  input done to start the engines ( extracted 
from the Nord-2502).
We could have the same elegant process, with only jsbsim, working stand alone, 
and working with FG, which should use the jsbsim property, and trigger FG ( 
why not) when used.

Thanks

Cheers
