The ABLE simulator allows a user to run and evaluate the actual CMU-900 or DLM-900 AOC application created by the GSE tool in a host environment. The AOC-900 software for the Airbus ATSU can not be evaluated with the ABLE simulator. The ABLE environment eliminates the need to utilize an aircraft as a test platform. ABLE allows the user to emulate the configuration of an aircraft. Aircraft configurations differ based on the number of device types installed and connected to the CMU-900/DLM-900. Additionally, ABLE allows the user to set variables (i.e., discrete inputs/outputs and programming pins) to simulate other types of connections.
