This unit is fitted to the C-130. The Avionics Systems Management Unit (ASMU) has been developed for transport aircraft, to allow aircrew to control, primarily, the cockpit display suite. Capable of operating as a peripheral device to the mission computer, it can also be configured to control subsystems with its own inherent menu structure. Typically a main menu and sub menu are displayed on dual monochrome matrix displays each of 11 lines of 24 characters. The ASMU interfaces to the aircraft via MIL-STD-1553B or ARINC 429 as appropriate. Mounted in the cockpit, the ASMU provides a point of contact for groundcrew to extract maintenance information.
