MULTIFUNCTION CONTROL DISPLAY UNIT (MCDU)
The multifunction control display unit (MCDU), shown in Figure 3--1, is
the principal pilot interface to the system. The function of the MCDU is
described in this section. The pilot must know the general rules and
operating characteristics of the MCDU to understand the specific
operations of the flight management system (FMS).
MCDU operation is designed to be simple and to minimize crew
workload in all phases of flight. The MCDU serves as the pilot interface
with the navigation computer, as well as other systems the FMS
interfaces. Pilots enter data using the alphanumeric keyboard and the
line select keys.
