Gyroplanes and gyrogliders
Modern light gyroplanes/gyrogliders used by recreational flyers are generally small flying machines that are very different from the first gyroplanes developed in the 1920s. Until recently, gyroplanes were mostly homebuilt and flew from small grass fields. Technological advances in factory-built light gyroplanes mean that they can now fly from established airfields, and are likely to attract increasing interest from both new aviators and pilots from other sectors of aviation.
Although gyroplanes derive lift from a rotor they differ significantly from helicopters in that the air flows up through the rotor, rather than downwards. Gyroplanes are in constant autorotation and may be considered to behave conventionally in the case of engine failure i.e. similar to a fixed-wing aircraft, albeit with a steeper glide angle.
The Australian Sport Rotorcraft Association administers gyroplane operations and issues pilot certificates to CASA-approved standards.
