Downlink Address Table
The downlink address table has the ground addresses and the company distribution for IMIs. There are no default entries for this table. You may enter a maximum of 20 IMIs in the table.
Airline Ground Address Table
The airline ground address table has the ground addresses with the identification of ADS uplinks that originate with the airline. There are no default entries for this table. You may enter a maximum of 5 ground addresses or 5 groups of addresses in the table.
Default Values Summary
Default values are non-modifiable values found in the operational software of the CPM/Basic and the CPM/ACMF. To cause the function to operate with new values, you must develop a customized AMI and load that software into the CPMs. These new values do not override the default values but are used instead of the default values. If the AMI fails, FMCFs use the default values.

FMCS -CDU FUNCTIONAL DESCRIPTION

General
The left and right CDUs operate independently to supply different pages of data with CDU keyboard entries. The CDU main interface is with the active FMCF for flight control. The CDUs interface with other systems. The CDUs also do back-up functions and alternate functions for some systems.
The CDUs receive inputs from these:
*
External systems

*
Flight deck panels

*
AIMS cabinets

*
Other CDUs.

The CDUs use the inputs to do these functions:
*
Menu control and access of systems

*
Alternate control panel functions

*
Alternate LNAV function

*
Alternate LNAV guidance

*
Alternate LNAV engage and disengage logic

*
Alternate navigation radio tuning

*
Bite and fault monitoring

*
Display and control

*
Liquid crystal display (LCD).

The CDUs supply data to these functions and components:
*
AIMS (CMCF, FMCF, and PDF)

*
LCD function

*
Navigation radios

*
Autopilot flight director system (AFDS)

*
Satellite data unit (SDU)

*
Passenger address/cabin interphone (PA/CI) controller.

Systems Access
Push the MENU key to access the MENU page. This MENU page shows the FMC and other systems the operator may access. The left and right CDUs are the main crew interface for preflight and inflight control. The crews use the CDUs and the mode control panel (MCP) to initialize the FMCFs during preflight. The flight crews use the CDUs to change the lateral and vertical flight profile inflight.
