Ditching
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, and it is a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water (including a runway excursion into water) are generally not considered water landings or ditching, but are considered accidents. Most times, ditching results in aircraft structural failure. Aircraft water landings By design Seaplanes, flying boats, and amphibious aircraft are designed to take off and alight on water. Alighting can be supported by a hull-shaped fuselage and/or pontoons. The availability of a long effective runway was historically important on lifting size restrictions on aircraft, and their freedom from constructed strips remains useful for transportatio ...

US Airways Flight 1549 (N106US) After Crashing Into The Hudson River (crop 1)
US Airways Flight 1549 was a regularly scheduled US Airways flight from New York City's LaGuardia Airport to Charlotte and Seattle, in the United States. On January 15, 2009, the Airbus A320 serving the flight struck a flock of birds shortly after takeoff from LaGuardia, losing all engine power. Given their position in relation to the available airports and their low altitude, pilots Chesley "Sully" Sullenberger and Jeffrey Skiles decided to glide the plane to ditching on the Hudson River near Midtown Manhattan. All 155 people on board were rescued by nearby boats. There were no fatalities, although 100 people were injured, 5 of them seriously. The time from the bird strike to the ditching was less than four minutes. The then-Governor of New York State, David Paterson, called the incident a "Miracle on the Hudson" and a National Transportation Safety Board (NTSB) official described it as "the most successful ditching in aviation history". Flight simulations showed that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Landing
An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight (such as a medical emergency). It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an forced landing, off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency. Types There are several different types of emergency landings for powered aircraft: planned landing or unplanned landing. * ''Forced landing'' – the aircraft is forced to make a landing due to technical problems. Landing as soon as possible is a priority, no matter where, since a major system failure has occurred or is imminent. It is caused by the failure of or damage to vital ...

Spacecraft
A spacecraft is a vehicle that is designed spaceflight, to fly and operate in outer space. Spacecraft are used for a variety of purposes, including Telecommunications, communications, Earth observation satellite, Earth observation, Weather satellite, meteorology, navigation, space colonization, Planetary science, planetary exploration, and Space transport, transportation of Human spaceflight, humans and cargo spacecraft, cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Geocentric orbit, Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other Astronomical object, celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations except for commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes, ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the " private transport" and recreational components of aviation, most of which is accomplished with light aircraft. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial adver ...

Pilot Error
In aviation, pilot error generally refers to an action or decision made by a Aircraft pilot#Airline, pilot that is a substantial contributing factor leading to an Aviation accidents and incidents, aviation accident. It also includes a pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention on International Civil Aviation, Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of "pilot error" does not include deliberate crashing (and such crashes are not classified as accidents). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs ...

Spin (aerodynamics)
In flight dynamics (fixed-wing aircraft), flight dynamics a spin is a special category of Stall (fluid dynamics), stall resulting in Autorotation (fixed-wing aircraft), autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient Yaw axis, yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its Lift (force), lift and Drag (physics), drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a cr ...

Engine Failure
A turbine engine failure occurs when a Gas turbine, gas turbine engine unexpectedly stops producing Power (physics), power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can also fail, such as Gas-fired_power_plant, ground-based turbines used in power plants or combined diesel and gas vessels and vehicles. Reliability Turbine engines in use on today's turbine-powered aircraft are very reliability (engineering), reliable. Engines operate efficiently with regularly scheduled inspections and maintenance. These units can have lives ranging in the tens of thousands of hours of operation. However, engine malfunctions or failures occasionally occur that require an engine to be shut down in flight. Since multi-engine airplanes are designed to fly with one engine inoperative and flight crews are trained for that situation, the in-flight shutdown of an engine typically does not constitute a serious safety of flight issue.

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has three regional offices, located in Anchorage, Alaska; Aurora, Colorado; and Federal Way, Washington. The agency also operated a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the time the CAA/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SpaceX Dragon
Dragon is a family of spacecraft developed and produced by American private space transportation company SpaceX. The first variant, later named SpaceX Dragon 1, Dragon 1, flew 23 cargo missions to the International Space Station (ISS) between 2010 and 2020 before retiring. Design of this version, not designed to carry astronauts, was funded by NASA with $396 million awarded through the Commercial Orbital Transportation Services program and contracted to ferry cargo under the Commercial Resupply Services (CRS) program. An improved version, the SpaceX Dragon 2, Dragon 2, was introduced in 2019 and has both crewed and cargo versions. The first un-crewed flight test (Crew Dragon Demo-1, Demo-1) took place in March 2019, followed by a crewed flight test (Crew Dragon Demo-2, Demo-2) in May 2020. Since those flight tests, the Crew Dragon has become one of the primary spacecraft ferrying crew to and from the ISS. While the Cargo Dragon continues to carry cargo under the CRS program. S ...

Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
