Integration Testing Station

HILS-based integration testing

The ITS is an integrated Hardware In the Loop Simulator (HILS) used for acceptance testing of sub-systems, verification purposes during integration and for system maintenance. The ITS extends traditional hardware in the loop simulation to provide fully automated verification of sub-systems such as FCUs, from automated text execution through to results verification and reporting. Available with DO-330 tool qualification evidence, the ITS is ideal for DO-178C developments where the time, effort and cost of verification process compliance can become enormous.

For clients, the ITS further supports on-site simulation, training, demonstration and maintenance on integrated aircraft. This high-fidelity, real-time dynamic simulator exercises the full functionality of FCUs, including injection of flight upset events and failure cases. The ITS is therefore ideal for system level training and demonstrations, with 3D visualisation on up to three external HD displays. Its built-in diagnostics suite also enables fast, on-site Remove & Replace (R&R) maintenance at both LRU and SRU levels. The ITS’ Ground Power Unit (GPU) powers the subsystems on-board aircraft during simulation and ensures that all simulations (especially long endurance simulations) remain uninterrupted by running the ITS from a built-in Uninterrupted Power Supply (UPS).
