Multifunction Control and Display Unit (MCDU)
The MCDU is the interface unit between the pilot and the FMC. It provides the
means for manually inserting system control parameters and selecting modes of
operation. In addition, it provides FMC readout capability as well as verification
of data entered into memory. Flight plan and advisory data are continuously
available for display on the MCDU.
The MCDU keyboard assembly provides a full alphanumeric keyboard combined
with mode, function, data entry, slew function keys, and advisory annunciators. In
addition, the keyboard assembly contains two integral automatic light sensors and
a manual knob to control display brightness.
Refer to the Controls and Indicators section in this chapter for a description of the
MCDU. The FMS pages shown throughout this chapter are examples only. Actual
pages may differ depending upon actual aircraft situations, engine type, and
selected options.
