An aircraft is a craft of the air. Balloons and paragliders certainly qualify as aircraft, as do blimps and dirigibles, even though they don't have wings. If it has fixed wings and an engine, it is an airplane. With fixed wings and no engine, it is a glider (most, but not all are also called sailplanes). If it has a rotary wing, it is either a helicopter or an autogyro. If the rotor is also the source of thrust, it is a helicopter. If the rotor is unpowered and another form of thrust is provided (typically a propeller), it is an autogyro. While we're at it, let's not forget the ultralight aircraft, and the amateur built (homebuilt) aircraft, which are certified in the experimental category. Is there a need for categories talking about the different kinds of airspace? For IFR vs. VFR flying? Is there a need to discuss different categories of pilot licenses? How about types of charts used for navigation? Perhaps something about aviation organizations, such as the Aircraft Owners and Pilots Association and the Experimental Aircraft Association. |
