CONTROL AND DISPLAY
GENERAL
The CMA-9000 FMS is a Flight Management Computer (FMC) embedded within a Multipurpose Control Display
Unit (MCDU), thus becoming an FMCDU. The MCDU function can be interfaced with up to seven other ARINC-
739 capable LRUs (ACARS, SATCOM, ACMS,…). The display section of the MCDU is a color Active Matrix
Liquid Crystal Display (AMLCD) providing fourteen lines of twenty-four characters.
The unit’s front panel presents a full alphanumeric keyboard, with special function keys. These special function
keys are mostly dedicated to FMS operations (e.g. INIT/REF, RTE, DEP/ARR, etc.). There are six line select
keys (LSK) on each side of the display area. The functions of the LSKs are specific to each screen page.
FMCDU FRONT PANEL
The front panel arrangement of the FMCDU is illustrated in Figure 2-1. The data is presented on a 3 X 4 inch
Active Matrix Liquid Crystal Display (AMLCD). The display format is partitioned into specifically defined areas.
