Getting familiar with the projet.

Hi, I'm new here and I'm amazed with the work already accomplished !I just have a few questions :-About the FMA Attitude controller :How is an input in the FMA translated ? Does it offset the attitude of the plane by the value of this input ?I can't see any pitot tube connected to the FMA so, how does it handle the "aerodynamic" gain change in the PID attitude control loop, with regards to the airspeed change.-About the Ardu autopilot :In an effort to understand the code, I'd like you to help me a bit. The only thing I know is that it seems to be written in C. I have some understanding of programming. I recently started to learn about pic microcontrollers. Could you give me enough information to help me get started. Programming platform ect...Thank you in advance :-)

    FMA output is analog. The code reads these signals and uses PID loops to control the plane.

    ArduPilot 2.1 and above can use a pitot tube for airspeed/throttle control.

    ArduPilot is based on Arduino. It's an open source hardware/software platform similar to C.
  • Hi,

    I am also a beginner and my ardu doesn't work yet ... but I am learning alot by reading the forums.

    This is a nice start.

    FMA
    Do you mean the stabilize X,Y ?
    It will not altitude hold , only stabilize in Pitch and roll....
