Recently updated, this comprehensive handbook explains the aerodynamics of helicopter flight, as well as how to perform typical helicopter manoeuvres, unlike many aviation training manuals which are strictly how-to guides. Beginning with the basics of aerodynamics, each step of the process is fully illustrated and thoroughly explained - from the physics of helicopter flying and advanced operations to helicopter design and performance - providing helicopter pilots with a sound technical foundation on which to base their in-flight decisions. Containing discussions on the NOTAR (no tail rotor) system, strakes, and frequently misunderstood principles of airspeed and high-altitude operations, this revised edition also includes the latest procedures and regulations from the Federal Aviation Administration.
