Airbus A380
The Airbus A380 is a very large wide-body airliner, developed and produced by Airbus until 2021. It is the world's largest passenger airliner and the only full-length double-deck jet airliner. Airbus studies started in 1988, and the project was announced in 1990 to challenge the dominance of the Boeing 747 in the long-haul market. The then-designated A3XX project was presented in 1994 and Airbus launched the €–billion ($10.7–billion) A380 programme on 19 December 2000. The first prototype was unveiled in Toulouse, France on 18 January 2005, commencing its first flight on 27 April 2005. It then obtained its type certificate from the European Aviation Safety Agency (EASA) and the US Federal Aviation Administration (FAA) on 12 December 2006. Due to difficulties with the electrical wiring, the initial production was delayed by two years and the development costs almost doubled. It was first delivered to Singapore Airlines on 15 October 2007 and entered service on 2 ...

Quadjet
A four-engined jet, sometimes called a quadjet, is a jet aircraft powered by four engines. The presence of four engines offers increased power and redundancy, allowing such aircraft to be used as airliners, freighters, and military aircraft. Many of the first purpose-built jet airliners had four engines, among which stands the de Havilland Comet, the world's first commercial jetliner. In the decades following their introduction, their use has gradually declined due to a variety of factors, including the approval of twin-engine jets to fly farther from diversion airports as reliability increased, and an increased emphasis on fuel efficiency. Design Podded engines The engines of a 4-engined aircraft are most commonly found in pods hanging from pylons underneath the wings. This can be observed in the Airbus A340, Airbus A380, and Boeing 747. Many military airlifters also feature this design, including the Antonov An-124, Boeing C-17 Globemaster, and Lockheed C-5 Galaxy. In ...

Megaproject
A megaproject is an extremely large-scale construction and investment project. A more general definition is "Megaprojects are temporary endeavours (i.e. projects) characterised by: large investment commitment, vast complexity (especially in organisational terms), and long-lasting impact on the economy, the environment, and society". Megaprojects refer not only to construction projects but also decommissioning projects, which are projects that can reach multi-billion budgets, and have a high level of innovation and complexity, and are affected by a number of techno-socio-economic and organizational challenges. The OFCCP Mega Construction Project (Megaproject) Program involves projects valued at over $35 million. Downsides Megaprojects are often affected by corruption, leading to higher cost and lower benefit. According to the European Cooperation in Science and Technology (COST), megaprojects are characterized both by "extreme complexity (both in technical and human terms) a ...

McDonnell Douglas MD-12
The McDonnell Douglas MD-12 was a large wide-body airliner concept planned by the McDonnell Douglas company in the 1990s. It was first conceived as a trijet larger than the MD-11, then stretched to a quadjet airliner. It was to be similar in size to the Boeing 747, but with greater passenger capacity through two full-length passenger decks. However, the MD-12 received no orders and was canceled. McDonnell Douglas then studied larger MD-11 derivatives named ''MD-XX'' without proceeding. Design and development Background McDonnell Douglas studied improved, stretched versions of the MD-11 trijet, named MD-12X"MDC brochures for undeveloped versions of the MD-11 and MD-12."

Hull Loss
A hull loss is an aviation accident that damages the aircraft beyond economic repair, resulting in a total loss. The term also applies to situations where the aircraft is missing, the search for its wreckage is terminated, or the wreckage is logistically inaccessible. The aviation industry uses the metric of "hull losses per 100,000 flight departures" to measure the relative risk of a given flight or aircraft. There is no official ICAO or NTSB definition. From 1959 to 2006, 384 of 835 hull losses were non-fatal. Constructive hull loss takes into account other incidental expenses beyond repair, such as salvage, logistical costs of repairing non- airworthy aircraft within the confines of the incident site, and recertifying the aircraft. Airlines typically have insurance to cover hull loss. Their policies—like many covering assets that are subject to depreciation—typically pay the insured a formulaic used-item value. A damaged aircraft will often simply be scrapped. ...

Range (aeronautics)
The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The fuel time limit for powered aircraft is fixed by the available fuel (considering reserve fuel requirements) and rate of consumption. Some aircraft can gain energy while airborne through the environment (e.g. collecting solar energy or through rising air currents from mechanical or thermal lifting) or from in-flight refueling. These aircraft could theoretically have an infinite range. Ferry range means the maximum range that an aircraft engaged in ferry flying can achieve. This usually means maximum fuel load, optionally with extra fuel tan ...
