PFD Operation
4-18
SkyView Pilot’s User Guide - Revision M
If you are on the ground, this will be under SETUP MENU > PFD SETUP > ADAHRS SOURCE
SELECTION.
ADAHRS Status
The ADAHRS labeled ACTIVE is the one that is being displayed on the PFD.
An ADAHRS labeled STANDBY is being used for cross-checking, but it is not being displayed on
the PFD.
PRIMARY / ALTERNATE ADAHRS Selection
The ADAHRS labeled PRIMARY is the one that will be preferentially chosen by SkyView as the
active ADAHRS.
An ADAHRS labeled ALTERNATE is one that is available to be used in the event of a failure or
problem with the primary ADAHRS. However, it normally won’t be chosen for display on the
PFD unless the primary ADAHRS has failed or has manually been disabled.
To change which ADAHRS is the PRIMARY ADAHRS, highlight an ALTERNATE ADAHRS and press
the PRIMARY button to elevate it to PRIMARY status.
To disable an ADAHRS until SkyView is next powered up, simply highlight it with the joystick and
press the DISABLE button.
To see the same comparison screen that is presented when a cross-check error occurs, press
the 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.
