Principles of Helicopter Flight Everything you need to know about helicopter aerodynamics. If you want more than just an overview of helicopter aerodynamics, we wholeheartedly recommend this manual by Walter Wagtendonk. Principles of Helicopter Flight explains the complexities of helicopter flight in clear, easy-to-understand terms, and is the type of manual the helicopter training industry has been waiting for. It provides pilots and students with important background knowledge on how helicopters fly, and, more important, why they sometimes dont. The aerodynamic factors associated with rotor stalls, mast bumping, wind effect, and other important concepts rotary pilots must know are covered in detail. Author profile: Wal Wagtendonk served in the Royal new Zealand Air Force, retiring as an A-2 instructor in 1960. He established one of New Zealand's best known theory and flight training establishments, Nelson Aviation College. The school became the first "approved" school to conduct both fixed-wing and helicopter courses in New Zealand, and many experienced helicopter pilots started their basic training under Wal's careful instruction. Format: January, 1996, soft cover, 288 pages, illustrated, glossary, indexed.
