A Control Display Unit (CDU) is used in remote operated gasfields placed on the seabed. It distributes power, control signals and chemicals arriving through the umbilical and pipelines from land to the other sub-sea structures.
The connection point – manifold – in the control distribution unit can be retrieved to the surface for maintenance and modifications.
It is also used as name of the interface device unit used to access the flight management computers (FMC), the main computers and software larger aircraft, especially airliners such as Boeing 737, 767 and 777.
