FINST 001

Explain the function of the DISPLAYS SOURCE selector.

AUTO:
• DEU 1 controls the Captain's outboard, Captain's inboard and upper display units.
• DEU 2 controls the First Officer's outboard, First Officer's inboard, and Lower Display units.
• When a DEU fails, the other DEU controls all display units.

ALL ON 1 or 2: (Used on the ground for maintenance purposes)
• Manually switches all display units to a single DEU.

- See Side 3 & 4 -

side 3

The DISPLAYS source panel, located on the forward overhead panel, contains source controls for the display electronic units (DEUs) and EFIS control panels.

Two DEUs receive data from sensors and airplane systems and supply data to the DUs. During normal operation, with the display SOURCE selector switch in the AUTO position, DEU 1 supplies data to the Captain outboard, Captain inboard and upper DUs while DEU 2 supplies data to the First Officer outboard, First Officer inboard and lower DUs. If a DEU fails, the remaining DEU automatically supplies data to all six displays. A single DEU failure will continue to supply each pilot with flight instrument information from independent sources. Each DEU receives data from both ADIRUs.

side 4

The display SOURCE selector, used on the ground for maintenance purposes, allows manual selection of either DEU 1 or DEU 2 for all six display units. If the displays are automatically or manually switched to a single DEU source, a
"DSPLY SOURCE" annunciation illuminates on the primary flight displays.
The CONTROL PANEL select switch determines which EFIS control panel controls the pilots' display functions. This switch should remain in NORMAL.
With the switch positioned to either BOTH ON 1 or BOTH ON 2, the selected EFIS control panel provides inputs for both sets of pilot displays.

FINST 002

Explain the function of the DISPLAYS CONTROL PANEL Select Switch.

NORMAL:
• Left EFIS control panel controls Capt's displays.
• Right EFIS control panel controls FO's displays.

BOTH ON 1 or 2:
• Manually switches control of displays to a single EFIS control panel.

- See Side 3 -

side 3

Note: When in the NORMAL position, a "DISPLAYS CONTROL PANEL" annunciation illuminates below the altitude indication showing a failure of the associated EFIS control panel.

FINST 006 (003-005 Removed)

Describe the alert associated with a single DEU failure.

Note: If a DEU fails, the remaining DEU automatically supplies data to all six displays. A single DEU failure will continue to supply each pilot with flight instrument information from independent sources. If the displays are automatically or manually switched to a single DEU source, a "DSPLY
SOURCE" annunciation illuminates on both PFDs below the Airspeed Indicator.

- See Side 3 -

FINST 007

The bar is removed when the flap lever is moved to the landing flap selected on the APPROACH REF page or when the flap lever is moved to flaps 30 or 40.

FINST 013
