Electronic Module sizes in MCU

Tue Dec 08, 2020 4:23 pm

Anyone having a reference document to illustrate the various MCU sizes used to indicate the description of Electronic module sizes.
eg 2 MCU etc
Any the History behind this numbering system.

MCU= Mode Control Unit? What exactly are you referring to?
This plane is built to withstand anything... except a bad pilot.

MCUs (Modular Concept Unit) are 7.64” high, 12.76” deep and a function of (Nx1.3”)-0.032” wide. I think they are defined in the ARINC 600 standard.

Wasn’t there a DIN standard for such things? Or, am I thinking of the modules the crew works with? “The end with the bottons and knobs and stuff”, not the part down in the equipment bays.
Never employ grandios verbiage when the utilisation of diminutive phraseology will suffice.
