The has long been a standard reference for pilots transitioning to advanced models and types and preparing for the Commercial Pilot knowledge and flight tests. This book bridges the gap between theory and practical application, covering the fundamentals of airplane aerodynamics and aircraft performance. Rules of thumb are used throughout as a means of presenting a clearer picture of the recommended performance parameters, and increasing understanding of the variable factors that affect aircraft operations such as altitude and temperature. Knowledge of these thumb rules will enable pilots to maximize performance when operating faster aircraft and at higher altitudes. Chapters are dedicated to:
