SV-ADAHRS-200/201 Installation and Configuration

5-8 SkyView System Installation Guide - Revision R

following parameters determine which ADAHRS is nominally preferred to be used. ADAHS can

also be manually disabled and enabled from this menu.

Enter the ADAHRS Source Selection Page under PFD SETUP > ADAHRS SOURCE SELECTION.

ADAHRS Status

The 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 the

PFD in normal operating conditions.

PRIMARY / ALTERNATE ADAHRS Selection

The ADAHRS labeled PRIMARY is the one that will be preferentially chosen by SkyView as the

active 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 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.

The SkyView system automatically switches to an alternate ADAHRS in the case of a

failure.

Airspeed Limitations

Use the values on this page to set IAS tape colors. Set V-speed (e.g., stall speed in landing

configuration) thresholds on the Airspeed Limitations Page (SETUP MENU > PFD SETUP >

AIRSPEED LIMITATIONS). If your aircraft limitations are expressed in TAS rather than IAS, set

Vne EXPRESSED AS: TAS.

If you do set Vne EXPRESSED AS: TAS, this will affect the Autopilot Pitch Axis MAXIMUM

AIRSPEED.
