The AAI Gyroplane
Autogyro, Autogiro, and Gyrocopter. These are all 'trade names' which have become synonymous with what the FAA has named this class of aircraft: Rotorcraft - "Gyroplane." Gyroplanes are 'Sustained Autorotative Flight' aircraft that have no power to the rotor in flight, the simple principle by which these aircraft fly. Groen Aeronautics Corporation - "Groen" (Groen Brothers Aviation was it predecessor) is recognized as the world's leading authority on Sustained Autorotative Flight. Groen formed American Autogyro International, Inc. "AAI" to produce affordable, fun, and safe kit gyroplanes for the kit aircraft market worldwide.
