Principles of Helicopter Flight by Walter J. Wagtendonk
Written with a building-block approach to learning to fly a helicopter, this comprehensive textbook shows pilots the underlying foundation of why the helicopter behaves the way it does. Discussing the complexities of helicopter flight in clear terms, this book explains the aerodynamic factors associated with rotor stalls, mast bumping, and wind effect. Also included are testing requirements and complete helicopter theory that every pilot can grasp and use to best master this type of aircraft.
