Course objective:

Gaining basic knowledge of the structure and operating principles of instrument, navigation and electrical systems on the aircraft.

Course contents:

Sources of electric power on the aircraft (storage batteries, generators). Organisation of electric networks, regulator, commutator and protective assemblies. Electric power converters and consumers. Organisation of instruments in the cockpit. Ways of data measuring and display. Direct and remote measuring. Synchronous transmission systems. Pitot-static aircraft system. Instruments for aerodynamic data. Geomagnetism and compasses. Gyroscopic instruments. Instruments of aircraft engines and fuel systems. Glass Cockpit concept, multifunction displays and integrated display systems. Analog electronics. Semiconductor devices. Operational amplifiers. ESD components. Digital electronics. Data conversion, numbering systems and logic assemblies. Structure of digital computers, hardware and software. Data buses. Optical fibres. Electromagnetic compatibility (EMC). Aircraft software, navigation databases. Aircraft communications.


Knowledge of operating principles of instrument, electromechanical and electronic assemblies and systems on the aircraft. Reading schemes and function diagrams for the purpose of efficient fault finding. Improvement of the technological process of maintaining these systems.

Learning outcomes:

Having passed the exam, the student will be able to: 1. Sketch block diagrams of aircraft electrical and electronic devices and systems. 2. Explain the principle of operation and practical application of aircraft instruments and electrical systems. 3. Calculate working parameters of aircraft electrical systems. 4. Connect existing knowledge of electrical systems with the specific characteristics of aircraft electrical systems. 5. Individually interpret a given topic in writing and orally through a seminar paper. These learning outcomes contribute to the following outcomes of the study programme of aircraft maintenance: - Classify levels of maintenance according to the impact on safety and costs of ordinary and extraordinary maintenance. - Distinguish aircraft maintenance according to MSG-2 and MSG-3 concepts. - Distinguish single parts of an aircraft in relation to the physical laws of flying and functioning of aircraft systems. - Apply standard maintenance procedures prescribed in the aircraft maintenance programmes. - Analyse errors in operational flying from the aircraft maintenance reliability programme. - Use English with aviation vocabulary at the level sufficient to understand the aircraft technical documentation and to apply procedures written in English.
