This well regarded series for students taking the commercial and airline transport pilot licences has been substantially revised to bring it into line with the new European Joint Aviation Requirements (JARs) for flight crew licensing. Each volume deals with the material required by one of the new JAR papers.This volume deals with those subjects covered in the 022 section of the aircraft general knowledge part of the syllabus. It continues to cover air data and gyroscopic flight instruments, compasses and inertial navigation systems. Electronic instrumentation, automatic flight control and in-flight protection systems have been included and updated, together with thrust control and powerplant and system monitoring instruments.Basic principles are covered as before, but emphasis on obsolete equipment and calculations has been reduced or removed as appropriate, permitting increased coverage of modern systems.The opportunity has been taken to simplify the presentation of information so as to aid study and revision work. Many test questions and answers have been included, based upon the JAR syllabus and style.
