What is the purpose of the variables spoiler_limit and air_spoiler_limit in the airplane geometry section of the flight model.cfg file? They don't appear to have any effect. For example, here is a screenshot of your default A320neo with the value of spoiler_limit set to 10. It does not affect either the spoiler deflection shown in the external view or the spoiler deflection shown by the simvar. Regardless of the value set for that variable, the spoiler position shown by the spoiler position simvars is 1 radian, or 57.3 degrees.
