Module Title:Aircraft Structures and Systems
Language of Instruction:English
Credits: 5
NFQ Level:7
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: This module will be taught by Lectures, Tutorials and by using Model & Actual Aircraft and Sample Questions.
Module Aim: The aim of this module is to introduce basic and intermediate aircraft structures and systems to the student, to enable them to understand how it applies to an aircraft operation and maintenance, and to develop basic analytical and troubleshooting skills essential to an aircraft technician.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Understand and explain the importance of airworthiness requirements in relation to structural strength
LO2 Define and describe the technical terms associated with the structure of an aircraft’s fuselage, wings, stabilisers, control surfaces and their construction
LO3 Demonstrate a good knowledge of the operation of the main systems found on an aircraft.
LO4 Explain the design, construction and operation of components and subsystems that comprise one of the main systems of a commercial aircraft
