    Status flags
    • Roll Angle (bit 1) - Indicates if Roll Angle is available/valid
    • True Track Angle (bit 12) - Indicates if true track angle is available/valid
    • Ground Speed (bit 24) - Indicates if ground speed available/valid
    • Track Angle Rate (bit 35) - Indicates if ground speed available/valid
    • True Airspeed (bit 46) - Indicates if true airspeed is available/valid

    Roll Angle

    Roll angle or bank angle tells you if the aircraft is banking to the left or to the right and how many degrees.

    Sign (bit 2) determines if the aircraft is banking left (1) or right (0). When the aircraft is flying straight sign may either set to 1 or 0 with zero angle.

    NOTE: If the status flag (bit 1) is not enabled ALL bits (2 through 11) need to be actively set to zero. NOTE2: LSB shows resolution of 45/256degrees, the total range of the field roll angle is 0-90.

    True Track Angle

    Is the direction the aircraft is flying relative to the ground and true north.

    NOTE: Sign flag (bit 13) determines West (1) and East (0). Sign is 1 then 315 degrees is transmitted as 45degrees. Or to get the direction 0-360 range you need to add 180 degrees when west is set to 1. NOTE2: If the status flag (bit 1) is not enabled ALL bits (2 through 11) need to be actively set to zero. NOTE3: LSB shows resolution of 45/256degrees, the total range of the field roll angle is 0-90.
