MCDU FUNCTIONS
MCDU SUBSYSTEM CONTROL (if configured)
The CMA-9000 FMCDU has the built in capability to act as a MCDU for external sub-systems such as ACARS,
SATCOM, ACMS, and DFDAU. After a cold start, automatic logon to an external sub-system is possible, if
configured accordingly. Typically, the unit is configured for automatic logon to the onside FMS (e.g. the FMS
function that is embedded in the unit).
The 11 FMS function keys can be configured for automatic logon to the onside FMS, if desired. Using this
capability, when the MCDU function is currently logged onto a sub-system other than FMS (e.g. ACARS),
pressing a FMS function key (e.g. LEGS) automatically logs off the other sub-system and logs onto the onside
FMS and access the appropriate page.
The MCDU MENU page displays all configured external sub-systems and the onside FMS.
Display MCDU MENU 1/X page by pressing [MENU].
Each configured sub-system has an associated line select key on the left side of the page. The onside FMS is
displayed at LSK 1L.
Up to 7 external sub-systems other than the onside FMS can be configured. A second page (MCDU MENU 2/2)
is provided when at least 6 sub-systems (including the onside FMS) are configured.
