SV-ADAHRS-200 and SV-ADAHRS-201
Proper installation of the SkyView ADAHRS 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 ADAHRS 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
dynamic magnetic fields (e.g., AC currents, non-constant DC currents, and non-stationary
