Measurement UnitsSV-ADAHRS-20X Installation and ConfigurationSet altitude, distance and speed, temperature, barometer, and pressure measurement units asdetailed in the How to Configure Displayed Units Section of this guide.ADAHRS Source Selection and ConfigurationSkyView systems support multiple SV-ADAHRS-20X modules for redundancy and manage failurescenarios by automatically switching to backup modules should an ADAHRS completely fail.Additionally, in the event that multiple ADAHRS disagree, the display will annunciate this withan on-screen alert that calls out which parameter(s) are not the same on all ADAHRS. Thefollowing parameters determine which ADAHRS is nominally preferred to be used. ADAHS canalso be manually disabled and enabled from this menu.Enter the ADAHRS Source Selection Page under PFD SETUP > ADAHRS SOURCE SELECTION.ADAHRS StatusThe ADAHRS labeled ACTIVE is the one displayed on the PFD.An ADAHRS labeled STANDBY will be used for cross-checking, but will not be displayed on thePFD in normal operating conditions.PRIMARY / ALTERNATE ADAHRS SelectionThe ADAHRS labeled PRIMARY is the one that will be preferentially chosen by SkyView as theactive ADAHRS that is displayed on the PFD.An ADAHRS labeled ALTERNATE is one that is available to be used in the event of a failure orproblem with the primary ADAHRS. However, it normally won’t be chosen for display on thePFD unless the primary ADAHRS has failed or has manually been disabled.To change which ADAHRS is the PRIMARY ADAHRS, highlight an ALTERNATE ADAHRS and pressthe PRIMARY button to elevate it to PRIMARY status.To disable an ADAHRS until SkyView is next powered up, simply highlight it with the joystick andpress the DISABLE button.To see the same comparison screen that is presented when a cross-check error occurs, pressthe COMPARE button at the bottom of the display.Press BACK to exit the ADAHRS Source Selection Page or press EXIT to return to the Main Menu.Either of these actions will save the ADAHRS source settings.The SkyView system automatically switches to an alternate ADAHRS in the case of afailure.SkyView System Installation Guide - Revision O 5-7
