Maximum angles, centi-Degrees wrong?

In all of the documentation it says the maximum, and minimum, roll and pitch angles are in centi-Degrees.


Maximum Bank Angle (ArduPlane:LIM_ROLL_CD)

The maximum commanded bank angle in either direction

  • Range: 0 9000
  • Increment: 1
  • Units: centi-Degrees

However (at least in ArduPlane 2.4) the units are actually normal degrees. Also, if they are centi-degrees then the range should be 0-900, not 9000.

My main worry is that all of a sudden someone fixes this and then my plane will have a maximum roll of 4.5 degrees and max pitch of 2.0 degrees.

Can either the documentation fixed to show the units are degrees with a 0-90 range, or can centi-degrees be actually used (do we need that much precision?) and a warning put out that the change is taking place and everyone should update their parameters.

Personally I vote for just fixing the documentation.

    Centi-Degrees?  Are the log instructions correct?

    In the Log file ATT record, the numbers report out in decimal form, such as -.09 and .22.  In the instructions for the log, it says these are "centi-degrees".  So 0.22 centi-degrees would be .0022 degrees (just like .22 centimeters would be .0022 meters).

    What is in the ATT record looks more like degrees than degrees x 100.  Is documentation correct or is the centi-degree used in code converted to degrees in the ATT record (making documentation incorrect)?

    Hi Eddie,
    They are in centi-Degrees, and always have been. What makes you think they aren't?
    Cheers, Tridge
