Esterline CMC Electronics recently delivered its 1000th multifunction control display unit (MCDU) for Airbus A320 family aircraft to Thales Avionics of France.
Low-rate production of the MCDU began in 2010 and has gradually increased to a steady pace of close to 100 units a month. Each A318/319/320/321 airliner has two MCDUs installed and they serve as the primary interface between the pilot and avionics subsystems, including the flight management system and aircraft communications, addressing and reporting system (Acars).
CMC (Hall 1 Stand B11) has supported Thales with the MCDU keyboard since 2002, with more than 5,000 of these units delivered to date. Based on the keyboard’s in-service record for quality and reliability, in 2008 Thales awarded CMC with a long-term contract to supply the entire MCDU, which includes an improved keyboard, LCD screen, backlight and electrical interface (see page 18).
