Glossary of Aeromodelling Terms

Aeromodelling	Aeromodelling is the activity of building and flying model aircraft. Aeromodelling is firstly a recreational pass-time. It also has local, national and international model aviation sports dimensions. Finally, with newly-available miniaturised remote-sensing and automatic navigation technology, aeromodelling is now being extended into commercial, military and scientific research areas.
ACTAA	ACTAA is the acronym for the ACT Aeromodellers Association, the Australian Capital Territory's peak body for model aircraft aviation. ACTAA is affiliated with MAAA and thus CIAM
CIAM	CIAM is the acronym for the FAI International Aeromodelling Commission, the international peak body for model aircraft aviation.
Control Line	See Wikipedia for a comprehensive article on Control line (model_aircraft)
CMAC	CMAC is the acronym for Canberra Model Aircraft Association. CMAC is affiliated with ACTAA and thus MAAA and CIAM
Control System	Control systems available for model aircraft include: free flight (uncontrolled), control line (tethered), radio control (from ground-based pilot), UAV (autonomous control from on-board computer, GPS receiver and attitude sensors). Please note that CMAC Flying Field only supports the operation of radio-controlled model aircraft and (historically)control-line models. Since 2007 MAAA has prohibited the operation of a UAV from or at recognised MAAA flying sites [including the CMAC Flying Field].
Free Flight	See Wikipedia for a comprehensive article on Free flight (model_aircraft)
MAAA	MAAA is the acronym for the Model Aeronautical Association of Australia the Australian peak body for model aircraft aviation. MAAA is affiliated with CIAM.
Model Aircraft	Model aircraft are divided into two classes : static models and flying models. In turn, flying models are subdivided into: fixed-wing, rotary-wing, aerostats (balloons) and space models (rockets). Flying models are further characterised by their control system, propulsive power source, their method of construction and their size, weight and scale authenticity. The FAI International Aeromodelling Commission (CIAM) defines a comprehensive set of aeromodelling disciplines including F1: Free Flight, F2: Control Line, F3: Radio Control and so on.
Power Sources	Powered model aircraft contain an onboard powerplant to propel the aircraft through the air. Electric motor and internal combustion are the most common propulsion systems, but other types include rocket, small turbine, pulsejet, compressed gas and tension-loaded (twisted) rubber band. See Wikipedia for a comprehensive article on Power Sources
Radio Control	See Wikipedia for a comprehensive article on Radio-controlled aircraft
UAV	See Wikipedia for a comprehensive article on Unmanned aerial vehicles or RPVs.
