Range and Endurance has been written mainly with the student, Private Pilot and new Commercial Pilot in mind, flying light single and twin-engine aircraft. However, pilots with greater experience may also enjoy reading this book as a refresher on range and endurance flying. Starting with a brief look at fuel technology, consideration is given to different fuel leaning procedures, then aircraft fuel systems, the practice and theory of fuel management, before going on to examine the all-important aspect of pre-flight planning and range and endurance from an aerodynamic point of view. It concludes with a selection of formulas related to fuel calculation problems for solving on the E6-B air navigation computer.
