Module Title:Piston Engine
Language of Instruction:English
Credits: 5
NFQ Level:7
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: Teaching will be conducted through lectures and practicals. The Institute MLE will be used to evaluate the student's understanding of the basic concepts during each section, including using multiple choice questions. The practical sessions will be used to back up the theory.
Module Aim: The aim of this module is to introduce the student to the principles of piston engine operation on aircraft.
