Spiral Pop-top – Pack of 10: Helicopter Spiral pop-top is a perfect outdoor toy for kids which uses the same lift principle as helicopters. This is the FAA’s primary resource for helicopter operations knowledge; it is essential reading for applicants preparing for the exams for private, commercial, or flight instructor pilot certificates with a helicopter class rating. In addition to a basic introduction to the helicopter, readers will find chapters on aerodynamics, flight controls, systems, performance, ground procedures, basic and advanced flight maneuvers, emergencies and hazards, attitude instrument flying, night operations, and aeronautical decision-making.


Previously titled Rotorcraft Flying Handbook, this new edition is designed for use by flight instructors, pilots preparing for a helicopter rating FAA Knowledge and Practical exam, and helicopter-rated pilots wishing to improve their knowledge.


Historically, much of the early helicopter experimentation developed from this concept of lifting surfaces operated as a kind of airscrew. Even today it is not too wide of the mark to use this term, especially if we take note of the screw-like spiral path made by the rotor blades when a helicopter rises straight up. But this is not the way it really works; for an understanding of what makes a helicopter fly it is necessary to take a different approach and consider the key phrase, “rotating-wing”.


A helicopter flies as does an aeroplane, by the movement of its wings through the air. These wings, of course, are whirling rotor blades. This is the essence of helicopter flight — “wings” rotating around a central shaft.


A fuller understanding of rotating-wing aircraft really begins with the workings of the fixed-wing aeroplane. Here lies the similarity — and, paradoxically, the difference — between the two types of aircraft. In the most basic terms, a wing is a fixed surface that will produce a lifting force when it is moved through the air with enough speed or, as an engineer would put it, with sufficient velocity. To appreciate why a wing has this property, we need to consider the substance called air.
