July 2015 The Hong Kong Polytechnic University Hong Kong Community College Subject Description Form Subject Code CCN2288 Subject Title Aircraft Electricity and Electronics Level 2 Credit Value 3 Medium of Instruction English Pre-requisite / Co-requisite/ Exclusion Nil Objectives This subject introduces basic concepts and fundamental principles of electric circuits applicable to ASE students. Students will develop ability for solving problems involving electric circuits and a skill for experimentation on electric circuits. Students will acquire general skills and knowledge in basic electricity and electronics for independent learning of other subjects that require such skills and knowledge. Intended Learning Outcomes Upon completion of the subject, students will be able to: (a) understand fundamental theories of electrical and electronic circuits. (b) understand basic principles of analogue electronic circuits. (c) understand basic principles of digital techniques with applications with electronic circuits. (d) apply basic electronic instrument to perform and report measurement for analysis. (e) describe the operation and basic principles of an aircraft electrical system.

Teaching/Learning Methodology Lectures are used to deliver and explain fundamental principles, theories and basic analysis techniques in electrical and electronic circuits, digital logic circuits, transformer and electric machines. Tutorials are used to provide an opportunity for students to clarify concepts and to have a deeper understanding of lecture material; problems and application examples are given and discussed. Laboratories are used to provide hands-on experience for students to make measurement, related concepts and theories to practice, acquire data, perform analysis and interpreting results. 2 July 2015 Assessment Methods in Alignment with Intended Learning Outcomes A variety of assessment tools will be used to develop and assess students’ achievement of the subject intended learning outcomes.
