10A comprehensive glossary of aviation terms, acronyms, and technical jargon explained in plain language.
Airline Deregulation
The removal of government controls over airline routes, fares, and market entry in the United States, enacted through the Airline Deregulation Act of 1978, triggering a global restructuring of the aviation industry.
Aviation HistoryComposite Revolution
The transition in aircraft construction from aluminum-dominated structures to carbon-fiber-reinforced polymer composites, epitomized by the Boeing 787 Dreamliner which uses composites for over 50% of its structural weight.
Aviation HistoryFly-by-Wire Revolution
The transformation of aircraft control systems from mechanical cables and hydraulics to electronic digital computers, pioneered commercially by the Airbus A320 which entered service in 1988.
Aviation HistoryJet Age
The era beginning in the 1950s when commercial aviation transitioned from piston-engined propeller aircraft to turbojet and turbofan-powered jets, fundamentally transforming global travel.
Aviation HistoryJumbo Jet
The popular nickname for the Boeing 747, the world's first wide-body commercial airliner, which entered service in 1970 and revolutionized mass air travel by doubling passenger capacity.
Aviation HistoryMaiden Flight
The first flight of a newly designed or newly built aircraft, marking the beginning of the flight-test program before the type receives regulatory certification.
Aviation HistorySound Barrier
The dramatic increase in aerodynamic drag experienced by aircraft approaching the speed of sound (Mach 1), once thought to be an absolute physical limit to flight speed.
Aviation HistorySupersonic Transport (SST)
A category of commercial aircraft designed to cruise faster than the speed of sound, exemplified by the Anglo-French Concorde and Soviet Tupolev Tu-144, both of which operated in the 1970s–2000s.
Aviation HistoryWide-Body Era
The period from 1970 onward characterized by the widespread adoption of twin-aisle wide-body aircraft, beginning with the Boeing 747, which dramatically increased passenger capacity and drove down per-seat costs.
Aviation HistoryWright Flyer
The first successful heavier-than-air powered aircraft, designed and built by Orville and Wilbur Wright, which made four brief flights at Kitty Hawk, North Carolina, on December 17, 1903.
