SV-ADAHRS-200/201 Installation and Configuration
SkyView System Installation Guide - Revision AA 5-13
Pitot/Static/AOA Pneumatic Installation Kit
To install, simply connect your static and pitot sources to the SV-ADAHRS-200/201. If you are
performing a retrofit installation, consider “teeing” off of existing lines using a tee fitting.
Reference the sticker on top of the respective module for pneumatic port identification.
Use a wrench to secure the mating pressure line fittings to the corresponding locations on the
SV-ADAHRS-200/201. Do not over-tighten.
If you purchased a Dynon Avionics AOA/Pitot Probe, note that it has pitot and AOA ports, but
no static port (a static port is included with the AOA, Pitot, Static Plumbing Kit). If you do not
purchase the Dynon Avionics AOA, Pitot, Static Plumbing Kit, you will need to provide your own
source of static pressure for the SV-ADAHRS-200/201.
If you have more than one ADAHRS in your SkyView system, all ADAHRS
calibrations are applied to all ADAHRS simultaneously. In other words, you
generally only need to go these steps once per system, provided all ADAHRS are
calibrated, installed and are connected via SkyView Network. However, if an
additional SV-ADAHRS-200/201 is installed and configured at a time after the
original installation and calibrations in this section have been performed, all setup
and calibration steps in this section of the SkyView Installation manual should be
performed as if the ADAHRS is being installed for the first time.
Dynon Avionics calibrates every SV-ADAHRS-200/201 during manufacture. After
the aircraft build is complete, an in-aircraft compass calibration must be
performed. Until the on-ground or the in-flight compass calibration is performed,
SkyView will display a Caution message: NEED COMPASS CAL. The compass
calibration procedure will calibrate all SV-ADAHRS-200/201s in the SkyView
network.
Performing an In-flight Compass Calibration after the On-ground Compass Calibration can
increase the accuracy of the compass’ magnetic heading. The best compass performance will be
achieved by perform the on-ground compass calibration, then performing the in-flight compass
calibration. It is not required that the in-flight compass calibration be performed immediately
after the on-ground compass calibration.
The on-ground compass calibration requires pointing the aircraft in four directions and
acquiring data at each direction. An accurate method of aligning the aircraft with magnetic
North, East, South, and West, such as an airport’s compass rose, is required. During the
compass calibration, the aircraft’s configuration and major systems should be in a state that
resembles flight conditions (i.e., the canopy should be closed, the aircraft’s pitch attitude
matches SkyView’s attitude depiction, the engine should be running, and all electronic devices
used in flight should be on).
