Orientation Settings - Adjust Roll / Adjust Pitch / Adjust Yaw
These entries allow for correcting for mounting orientation by up to 30 degrees. Adjust the roll
and pitch setting as required to make the adjustment. When the knob is pressed after making the
adjustment, the roll and pitch displayed on this page will reflect the effect of the new setting. It
is possible that some interaction between the settings may be observed if the settings are large.
Roll and pitch can be adjusted to zero the roll and pitch data displayed (assuming the airplane is
resting in a wing level/nose level position).
The yaw entry must be made by measuring the orientation of the AHRS box with respect to the
longitudinal axis (centerline) of the airplane from a top-down perspective. Note that a right entry
indicates the AHRS is mounted with its axis pointing to the right of the airplane longitudinal axis
in the direction of the nose.
CAUTION:
Adjusting the roll, pitch or yaw orientation of the AHRS requires will reduce the accuracy
of the magnetometer data. A fine magnetometer calibration should be performed after these
settings are changed.
2.3 Adaptive AHRS Digital Magnetometer Installation
The digital magnetometer supplied with your adaptive AHRS includes internal accelerometers to
sense the orientation of the magnetometer automatically. This allows great flexibility in the
mounting of the magnetometer, but determining the location of the magnetometer requires
considerable care due to the magnetometer's sensitivity to magnetic disturbances generated by
the airplane.
No periodic maintenance is required for the magnetometer, although it is desirable to mount it in
a location where it is not exposed to water, and allows access to it if necessary. Keep in mind
that
