Benefits
-
Flexible and scalable
The TCDU is operational program control (OPC) configurable. This allows you to consolidate three separate hardware part numbers into a single part number that emulates three keyboard layouts (CDU, MCDU, FANS MCDU). The TCDU is also provisioned with two additional connectors for system interfaces supporting future capabilities. -
Interchangeable with flight management systems
The TCDU is compatible with the Boeing Flight Management System (BFMS) and legacy flight management systems, provided that the flight management computers are installed as a pair (two BFMCs or two legacy FMCs) and the keyboard layout on the TCDU and legacy CDU match. -
Lower maintenance cost
The physical buttons on a traditional CDU easily wear out or become damaged, causing unnecessary maintenance costs and potential flight delays. The durability of the glass touchscreen has shown to be significantly more reliable, reducing maintenance costs. -
Weight savings
The modern architecture of the TCDU reduces weight by three pounds (per two units). Lower weight translates to fuel saving, which helps support industry sustainability targets.
Services and Support
Training updates to describe the new and improved features are underway. Training will be released through the MyBoeingFleet common download service upon regulatory approval.
Minor updates to graphics and nomenclature will be released for Maintenance Training services subscribers. The TCDU will not change maintenance operations; therefore, hardware difference training is not required.
Repair service is available for worldwide support of warranty and non-warranty repairs.
TCDU spares can be ordered through the Boeing Parts Page accessed through MyBoeingFleet.
The TCDU is compatible with the Boeing Flight Management System (BFMS) and legacy flight management system, assuming the TCDU is in the same keyboard configuration as the CDU, MCDU, or FANS MCDU, the TCDU is an acceptable replacement.
