SV-ADAHRS-200 and SV-ADAHRS-201
Proper installation of the SV-ADAHRS-200/201 module(s) is critical. PFD
performance is significantly linked to a proper ADAHRS installation. The
installation location must meet all of the mechanical, magnetic, orientation, and
environmental requirements detailed below.
An SV-ADAHRS-200/201 installation location should be a rigid surface within 12 feet
longitudinally and 6 feet laterally of the aircraft's center-of-gravity. Figure 1 illustrates this
criterion.

The location should also be magnetically benign. Given that it may be difficult or impossible to
avoid all sources of magnetic interference, it is possible to characterize and compensate for
small, static magnetic fields with calibration. Calibration cannot, however, compensate for
