Integrated Modular Avionics
- Department of Measurement
Integrated Modular Avionics (IMA) course focuses on the latest concept used to the development and design of aircraft electronics (avionics), which is building on software units instead of a distributed hardware systems. The IMA concept uses high-speed data links to exchange data in scheduled air transport services. The current regulatory basis and shared airspace define the requirements for accuracy, reliability and functionality of electronic systems and their behavior in case of a failure. Students will learn the details regarding the requirements of the safety-critical multi-sensor systems, methods of data processing of overdetermined systems, fault detection algorithms, the method of primary/secondary system switching of a control system in parallel architectures, data bus technologies and methods of avionics testing/certification.

- Syllabus of tutorials:
Seminars are focused on practical exercises where selected algorithms are used to process data from sensors, error detection algorithms (FDIR) and algorithms for the fusion of data from different sources are evaluated. The exercises bring sensor information to a computer station where we implement the data processing and display software components. Seminars will take place regularly and it is assumed the students perform gradual development from the area of sensor data processing of an exemplary sensor system to the display system generated by a professional tool. Exercise is conceived as a gradual expansion of the basic tasks. For individual work on the project sensor units with wireless interfaces are available. The lab is intended mainly on the issue of collecting data from the measuring devices and then homework to solve data processing algorithms. Students will report their solutions in work descriptions which will be evaluated through the term.
