    Hi there,

    since two days i'm trying to get the "theoretically" values of aileron and elevator position, if the autopilot is on and holding, for example, the high. Anyone an idea?

    Thx, and best regards

    I'm not sure what you mean by "theoretically"...

    I can think of 3 values: the actual position of the elevator, the elevator position commanded by the autopilot and the yoke position.

    Related will be these simulation variables:

    YOKE Y POSITION
    ELEVATOR POSITION
    ELEVATOR DEFLECTION
    ELEVATOR DEFLECTION PCT

    or even:

    ELEVATOR TRIM POSITION
    ELEVATOR TRIM INDICATOR
    ELEVATOR TRIM PCT


    I guess the AP will set one of the first two values. The other two will change accordingly. For an airbus, the FBW might control the elevator trim as well.

    Hallo,

    I only know, that these information stands in the aircraft.cfg. I have not found a variable in the simconnet SDK for this information.

    example C172
    elevator_up_limit = 28.0 //Degrees
    elevator_down_limit = 21.0 //Degrees
    aileron_up_limit = 20.0 //Degrees
    aileron_down_limit = 15.0 //Degrees
    rudder_limit = 24.0 //Degrees
    elevator_trim_limit = 19.5 //Degrees

    Regards Michael

    Look in the SDK under Aircraft Controls data.

    ELEVATOR POSITION

    Percent elevator input deflection

    Position (-16K to 0) -16K = full down

    then you may be able to use the cfg files
