Aircraft Engineering Principles covers the essential mathematics, electrical principles, mechanical principles, physical principles and aerodynamics, and adds a new chapter on electrical power supplies and distribution systems and more on flight aerodynamics. It is for anyone studying for licensed maintenance engineer status as well as those working to the range of aeronautical engineering qualifications. It meets international regulatory requirements and qualifications for aircraft engineers, that are increasingly globally harmonised; and also serves as a reference for professionals in aircraft manufacturing and operation. In particular, it covers Modules 1, 2, 3, 4, 8 and 11.1 of JAR-66/ECAR-66 in full and to a depth appropriate for those engaged in aircraft maintenance certification and will also provide a valuable reference for those taking ab initio programmes in JAR-147/ECAR-147 and FAR-147. It also suits the general requirements of introductory aerospace engineering courses at undergraduate level. Numerous written and multiple-choice question papers are provided at the end of each chapter, and interactive question papers are provided in the eBook+ version of the book.
