The Advanced Pilot's Flight Manual has long been a standard reference for veteran pilots preparing for the commercial written and flight tests. Explanations bridge the gap between theory and practical application, covering the fundamentals of airplane Lift, Weight, Drag, and Thrust, as well as the effects of variable factors such as altitude and temperature on the operation of the aircraft. In this completely updated sixth edition, Kershner has added the 651 multiple-choice questions on airplanes from the FAA Commercial Pilot Written Test Book, with answers and explanations.
