[Jsbsim-devel] Aerosurface scale

[Sam H. <sam...@gm...>]

Dear Jon, or anyone else,

I have a quick question regarding the aerosurface component.
What does the gain represent? I currently have the following elevator 
control:

   <COMPONENT NAME="Pitch Trim Sum" TYPE="SUMMER">
       INPUT        fcs/elevator-cmd-norm
       INPUT        fcs/pitch-trim-cmd-norm
       CLIPTO       -1 1
    </COMPONENT>
    <COMPONENT NAME="Elevator Control" TYPE="AEROSURFACE_SCALE">
       INPUT         fcs/pitch-trim-sum
       MIN            -0.5
       MAX           0.5
     </COMPONENT>
    <COMPONENT NAME="Pitch Feedback" TYPE="PURE_GAIN">
      INPUT        velocities/q-rad_sec
      GAIN         -0.003
    </COMPONENT>
    <COMPONENT NAME="Elevator Control Aug" TYPE="SUMMER">
       INPUT        fcs/elevator-control
       INPUT        fcs/pitch-feedback
       CLIPTO       -0.5 0.5
    </COMPONENT>
     <COMPONENT NAME="Futaba Servo" TYPE="SECOND_ORDER_FILTER">
       INPUT         fcs/elevator-positioning
       C1            0
       C2            0
       C3           950
       C4           1
       C5           40
       C6           950
       OUTPUT        fcs/elevator-pos-rad
     </COMPONENT>


In the Elevator Control section, do I need a gain value? Do I need to 
specify the output?

Thanks a lot!
Sam
