Cabin System Simulation Equipment

Custom-Tailored Graphical Simulations

In addition to the provision of automated testing equipment, Verified Systems has developed various custom-tailored graphical simulations for cabin equipment that was either not (yet) available at the customers site or very large, expensive and/or complex to be set up in original hardware. Such simulations cover specific cabin controller I/O systems like the complete handling of the main communication busses in the aircraft cabin including all connected passenger sub-devices, or they cover the functionality of specific connected controllers, like the communication aspects of a whole In-Flight-Entertainment system of an aircraft.

Hardware/Software-Integration Testing of Cabin Controllers

Automated HSI Testing Projects for Airbus Cabin Controllers

Since the foundation of Verified Systems, we have performed automated HSI testing projects for Airbus cabin controllers for various civil aircraft families, from A318, A320, A330, A340, A350 to A380, including the associated Freighter versions A330F, A350F and A380F. These cabin controllers are safety-critical hard-real time systems up to critically level DAL-B, which deal with a significant number of input and output signals (up to about 100.000).

HSI-Testing for Oxygen Supply Controller

Beginning already in 2011, Verified Systems performed Hardware/Software-Integration Testing for the Oxygen Supply Controller Module (OSCM) for the Airbus A350 Family. This included the architecture and setup of the HSI testrig as well as the excution of the whole testing campaigns starting with the derivation of test cases from requirements until the final test campaign for DO-178B DAL-B certification of the software.

IMA Module OS and Configuration Testing

Airbus A350 Integrated Modular Avionics (IMA)

Modern aircraft such as the Airbus A350 use Integrated Modular Avionics (IMA) to replace specialized controllers with powerful general-purpose platforms. Core Processing Input/Output Modules (CPIOMs) enable multiple safety-critical real-time applications of varying criticality levels, up to DAL-A, to run securely on the same hardware. They provide advanced time and space segregation, flexible I/O management, and standardized APIs, while reducing development, certification, testing, and maintenance costs through highly configurable system architectures.
