GA aircraft enable people, especially those in smaller communities and remote areas, to move quickly and efficiently across the country and around the world for both business and pleasure. GA is disproportionately important because it touches so many sectors of the economy – from the helicopters transporting accident victims to hospitals, to corporate jets carrying executives to meetings, to single piston engine aircraft flown by enthusiasts on the weekends.
2.02 Classes of GA Aircraft
MergeGlobal grouped GA aircraft into the following classes that are consistent with Federal Aviation Administration (FAA) classifications:
2.02.1 Single-engine piston-powered airplanes5 comprise over 80% of the current GA fleet in the United States and are the most common Personal-Use aircraft, thanks to their relatively low acquisition cost. The single piston engine drives a single propeller, and burns relatively expensive aviation gasoline (avgas).
2.02.2 Multi-engine piston-powered airplanes usually have two piston engines driving separate propellers. As with single piston aircraft, they use aviation gasoline, and Personal-Use accounts for much of their flight time.
2.02.3 Single-or Multi-engine Turboprop airplanes are powered by one or more turbine engines that drive propellers and burn aviation kerosene (jet fuel). Turboprop aircraft typically are larger, faster, and more expensive than piston aircraft. Turboprops are flown for a wide variety of purposes but are most often flown for business, corporate, and other professionally crewed purposes.
5 In accordance with industry norms, Airplanes are fixed-wing aircraft, Rotorcraft are rotary-wing aircraft (or, helicopters), while the term Aircraft includes both airplanes and helicopters.
2.02.4 Jet airplanes have two or three turbofan engines and offer the greatest speeds and range capabilities of all GA aircraft. Due to the expense and professional requirements of their operation, jets are most commonly operated by corporate and government users. For purposes of this study, jets are further segmented by weight class into three categories (light, medium, and heavy) to capture significant cost and use differences.
