In summary, Aspire 400 is a Satellite Data Unit (SDU) installed on an aircraft to allow for aircraft-to-satellite communication. The link to the Aspire 400 product details what type of communication is allowed, how it's made, and what it's used for on the aircraft. More information can also be found by clicking on the SATCOM Diagram.
One of the many features of this SDU is to be configured to connect to a display unit in the cockpit. An example of a cockpit display unit, Honeywell's Multi-Function Control and Display Unit (MCDU) (https://aerospace.honeywell.com/en/products/cockpit-systems/multi-function-control-and-display-unit). For the SDU to connect to an MCDU, their communication protocol needed to be developed to our industry standards of ARINC-739 (https://standards.globalspec.com/std/223119/ARINC%20739). |
