The course Integrated Modular Avionics (IMA) focuses on a modern concept of the approach to the development and design of aircraft electronics (avionics), where the transition from distributed HW systems to SW blocks. They use high-speed connections to exchange data in applications related to paid air transport. The existing regulatory basis and airspace sharing define the requirements for the accuracy, reliability, and functionality of electronic systems even in the event of a failure. In the course, students will learn details about the requirements for so-called safety-critical multi-sensor systems, methods of data processing from predetermined systems, fault detection methods, selection of primary computer and control system in parallel architectures, bus technology, and methods of testing/certification of aircraft instruments.


Processing of laboratory tasks and submission of required reports. Processing of individual work.

Osnova cvičení:

Exercises are focused on the transmission of data from sensors using digital buses used in aviation, then they are focused on the field of electromagnetic compatibility. These are online exercises, which are presented in the form of a video presentation and then individual processing of the data provided.

The next part is focused on data processing from aircraft sensors and systems - error detection algorithms (FDIR) and algorithms for data fusion from various sources.

Cíle studia:

The goal of the study is to gain a practical view of data processing in aviation and its use for flight control.
