Recall the function of the two aircraft Versatile Integrated Avionics units (VIAs)

Two VIAs provide the following functions: data display, flight management computing, central aural warning, master warning/caution light activation, and flight data acquisition

 Normally VIA-1 provides data for the DUs 1 – 3 and VIA-2 provides data for the DUs 4 - 6

 In case of failure, either VIA unit will automatically provide data for all DUs

6

Recall the function of the System Display Control Panel (SDCP)

Q image thumb

The SDCP, located on the center pedestal, allows selection of system synoptics, and adjustment of DU brightness

System Cues - Selects applicable system for SD display

ND Switch – With 1 or more DUs inop, causes the existing SD to become an ND

CONSEQ/STATUS/ MISC Switches - Displays respective page on SD

**Note: Individual DUs can be turned off by rotating the respective BRT knob fully counterclockwise through a detent. However, turning all six BRT knobs fully counterclockwise will cause all six DUs to default to full brightness

 2 - Captain uses VIA-2

 CAPT ON 2 light illuminates amber (If First Officer’s selection is 1, F/O ON 1 light will illuminate

21

Recall the function of the Inertial Reference System (IRS) control panel

Q image thumb

Flashing NAV OFF Light

 During alignment, ADIRU does not receive present position initialization within 5 to 10 minutes of turn on

 Present position entry fails the comparison test with either the stored or calculated present position

 

NAV OFF Light

 ADIRU is off

 ADIRU is in align mode

 ADIRU failure

 

Mode Selector

 OFF - Turns ADIRU off

 NAV - Normal position

 

The inertial reference function of the ADIRU provides air data and inertial reference information to the PFDs and NDs

ADIRU-1 is normally powered by the EMER AC bus and backed up by the aircraft battery

An independent back-up battery will provide power to ADIRU-2 for a minimum of 30 minutes if normal power is lost (retains heading, attitude and position)

**Note: Upon throttle advancement for takeoff, FMS position will be updated to the runway threshold

**Note: Normal alignment takes about 10 minutes. A fast (3-minute) realignment can be initiated by cycling the selector from NAV to OFF to NAV w/in 5 seconds
