DISPLAYS SOURCE Select Panel
The DISPLAYS source panel, located on the forward overhead panel, contains
source controls for the Display Processing Computer (DPCs) and EFIS control
panels.
The MAX Display System (MDS) utilizes two identical DPCs. Each DPC
interfaces with airplane subsystems and sensors to collect data. The collected data
is then processed and displayed on the flight deck DUs.
Each DPC is capable of providing completely independent sources of flight
information presented on the Captain's and First Officer's displays. Normally DPC
1 supplies data to the Captain's displays, while DPC 2 supplies data to the First
Officer's displays. Automatic switching is provided to select which DPC drives all
four displays after a single DPC failure.
The DISPLAYS SOURCE select switch is located on the DISPLAYS Panel. The
DISPLAYS SOURCE select switch allows the crew to manually select which
DPC drives the DUs overriding the automation. The AUTO POSITION allows the
automation to determine which DPC supplies data to each display and adjusts the
source depending on various DU health and DPC failure conditions. If the
displays are automatically or manually switched to a single DPC source, a DSPLY
SOURCE 1 or 2 alert is shown on the primary flight displays.
