AUTO Position Operation
The AUTO position of the DSPL CTRL switch on the L ISSP causes the CPM/GG (M010) in the left AIMS cabinet to send data to the left outboard DU and left inboard DU.
The AUTO position of the DSPL CTRL switch on the CDCP causes the CPM/GG (M011) in the left AIMS cabinet to send data to the upper center DU and the lower center DU.
the AUTO position of the DSPL CTRL switch on the R ISSP causes the CPM/GG (M011) in the right AIMS cabinet to send data to the right outboard DU and right inboard DU.
The CPM/GG (M010) in the right AIMS cabinet is the spare.
ALTN Switch Operation or One Channel Failure
The ALTN position of the switches changes the source of display data.
With the display control switches in AUTO, failures also cause the source of display data to change.
When you put the DSPL CTRL switch on the L ISSP in the ALTN position, or the CPM/GG (M010) in the left AIMS cabinet fails, the CPM/GG (M011) in the left AIMS cabinet sends data to the captain DUs.

PRIMARY DISPLAY SYSTEM -DISPLAY CONTROL FUNCTIONAL DESCRIPTION
When you put the DSPL CTRL switch on the CDCP in the ALTN position, or CPM/GG M011 in the left AIMS cabinet fails, the CPM/GG (M010) in the right AIMS cabinet sends data to the upper center and lower center DUs.
When you put the DSPL CTRL switch on the R ISSP in the ALTN position, or the CPM/GG (M0011) in the right AIMS cabinet fails, CPM/GG M010 in the left AIMS cabinet sends data to the first officer’s DUs.
For any of the above conditions all display functions are available and there is no reduction in system capability and functionality. There are no flight deck effects set.
ALTN Switch Operation and One Channel Failure
Alternate switch operation and one channel failure together cause the display system to go to a limited format operation. The total display system has the capability to show four critical and two essential formats.
With all other conditions normal, the outboard display units will show PFDs. The inboard display units will show NDs. The upper center DU will show EICAS and the lower center DU will show the secondary engine display.
If the CPM/GG (M010) in the left AIMS cabinet fails and the captain display control switch is in the alternate position, CPM/ GG (M010)in the right AIMS cabinet sends data to the left outboard (LOB), left inboard (LIB), and upper center DUs. CPM/ GG (M011) in the right AIMS cabinet sends data to the right outboard (ROB), right inboard (RIB) and lower center DUs. This causes the display system to go to the limited format mode. For this condition there are no flight deck effects and no dispatch limitations.
If the CPM/GG (M011) in the left AIMS cabinet fails and the center display control switch is in the alternate position, CPM/ GG (M010)in the left AIMS cabinet sends data to the LOB, LIB, and upper center DUs. CPM/GG (M011) in the right AIMS cabinet sends data to the ROB, RIB and lower center DUs. This causes the display system to go to the limited format mode. For this condition there are no flight deck effects and no dispatch limitations.
If the CPM/GG (M010) in the right AIMS cabinet fails and the first officer display control switch is in the alternate position, CPM/ GG (M010)in the left AIMS cabinet sends data to the LOB, LIB, and upper center DUs. CPM/GG (M011) in the left AIMS cabinet sends data to the ROB, RIB and lower center DUs. This causes the display system to go to the limited format mode. For this condition there are no flight deck effects and no dispatch limitations.

Two Display Channel Failures
Two failures cause the display system to go limited format operation. The total display system has the capability to show four critical and two essential formats.
With two failures, the system has the capability for:
