Annotation This series is specifically tailored to provide the information necessary to prepare an applicant for FAA mechanic certification with airframe and/or powerplant (A & P) ratings. These textbooks are designed for use by instructors and applicants preparing for the FAA Airframe Knowledge and Practical Exams, but also serve as an invaluable reference guide for certificated technicians who wish to improve their knowledge and practice. Chapter structure has been designed to ensure consistent and efficient internalisation of the material presented. Photographs and detailed drawings illustrate concepts, improve understanding, and increase retention. This volume of the series emphasises theory and methods of practical application within the overall topic of the airframe of an aircraft: how it is built, maintained, and repaired. It covers subjects such as airframe construction features, assembly and rigging, fabric covering, structural repairs, and aircraft welding. The specific topics addressed include Aircraft Instrument Systems, Communication and Navigation, Hydraulic and Pneumatic Power Systems, Aircraft Landing Gear Systems, Aircraft Fuel System, Ice and Rain Protection, Cabin Environmental Control Systems, and Fire Protection Systems.
