British Airways Flight 5390
British Airways Flight 5390 was a flight from Birmingham Airport in England for Málaga Airport in Spain. On 10 June 1990, the BAC One-Eleven 528FL suffered explosive decompression resulting in no loss of life. While the aircraft was flying over Didcot, Oxfordshire, an improperly installed windscreen panel separated from its frame causing the captain to be sucked out of the aircraft. The captain was held in place through the window frame for twenty minutes until the first officer landed at Southampton Airport. Aircraft and crew The ''County of South Glamorgan'' was a BAC One-Eleven Series 528FL jet airliner, registered as The aircraft first flew on 8 February 1971, and was delivered to Bavaria Fluggesellschaft on 26 February 1971. It was later transferred to Bavaria Germanair in 1977, Hapag-Lloyd Flug in 1979, British Caledonian in 1981, and finally to British Airways in 1988. The captain was 42-year-old Timothy Lancaster, who had logged 11,050 flight hours, including 1,075 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncontrolled Decompression
Uncontrolled decompression is an unplanned drop in the pressure of a sealed system, such as an aircraft cabin or hyperbaric chamber, and typically results from human reliability, human error, fatigue (material), material fatigue, engineering failure, or impact (mechanics), impact, causing a pressure vessel to vent into its lower-pressure surroundings or fail to pressurize at all. Such decompression may be classed as ''explosive, rapid'', or ''slow'': * Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the Paranasal sinuses, sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma. * Rapid decompression may be slow enough to allow cavities to vent but may still cause serious barotrauma or discomfort. * Slow or gradual decompression occurs so slowly that it may not be sensed before Hypoxia (medical), hypoxia sets in.

British Caledonian
British Caledonian (BCal) was a British private independent airline which operated out of Gatwick Airport in south-east England during the 1970s and 1980s. It was created as an alternative to the British government-controlled corporation airlines and was described as the "Second Force" in the 1969 Edwards report. It was formed by the UK's second-largest, independent charter airline Caledonian Airways taking over British United Airways (BUA), then the largest British independent airline and the United Kingdom's leading independent scheduled carrier. The carrier slogan was ''Let's go British Caledonian'' in the 1970s and ''We never forget you have a choice'' in the 1980s. The BUA takeover enabled Caledonian to realise its long-held ambition to transform itself into a scheduled airline. The merged entity eventually became the UK's foremost independent, international scheduled airline. A series of major financial setbacks during the mid-1980s combined with the airline's inability ...

Cholsey
Cholsey is a village and civil parish south of Wallingford in South Oxfordshire. In 1974 it was transferred from Berkshire to Oxfordshire, and from Wallingford Rural District to the district of South Oxfordshire. The 2011 Census recorded Cholsey's parish population as 3,457. Cholsey's parish boundaries, some long, reach from the edge of Wallingford into the Berkshire Downs. The village green is called "The Forty" and has a substantial and ancient walnut tree. Winterbrook was historically at the north end of the parish adjoining Wallingford and became part of Wallingford parish (run by its Town Council) in 2015. Winterbrook Bridge, which carries a by-pass road across the River Thames, is in the parish. Cholsey was one of the two main homes of the late author Dame Agatha Christie (the other being the village of Galmpton on the south Devon coast). John Masefield, poet laureate, lived at Lollingdon Farm in Cholsey from 1915 to 1917. History A Bronze Age site has been found bes ...

PTSD
Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that can develop because of exposure to a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress but instead may express their memories through play. A person with PTSD is at a higher risk of suicide and intentional self-harm. Most people who experience traumatic events do not develop PTSD. People who experience interpersonal violence such as rape, other sexual assaults, being kidnapped, stalking, physical abuse by an intimate partner, and i ...

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advisories'' (known as ''flight infor ...

Distress Call
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by a serious or imminent danger and requires immediate assistance.Aeronautical Information Manual U.S. Federal Aviation Administration, 2016 Use of distress signals in other circumstances may be against local or .

Descent (aeronautics)
In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ''ascent'' or '' climb''. Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below and preferably below , respectively the maximum temporary safe altitude for an unpressurized aircraft and the maximum safe altitude for extended duration. An example of explosive decompression is Aloha Airlines Flight 243. Involuntary descent might occur from a decrease in power, decreased lift (wing icing), an increase in drag, or flying in an air mass moving downward, such as a terrain induced downdraft, near a thunderstorm, in a downburst, or microburst. Normal descents Intentional descents might be undertaken to land, avoid other air traffic or poor flight conditions (turbulence, icing conditions, or bad weather), clouds (particularly under visual flight rules), to se ...

Brace Position
To assume a brace position or crash position is an instruction that can be given to prepare for a crash, such as on an aircraft; the instruction to "Brace for impact!" or "Brace! Brace!" is often given if the aircraft must make an emergency landing on land or water. There are many different ways to adopt the brace position, with many countries adopting their own version based on research performed by their own aviation authority or that of other countries. The most common in passenger airliners being the forward-facing seat version, in which the person bracing places their head against or as close as possible to the surface it is likely to strike (and in the process bending over to some degree), placing their feet firmly on the floor, and their hands either on their head or the seat in front. Types of brace position There are many different ways to adopt the brace position, with many countries adopting their own version based on research performed by their own aviation authorit ...

Autopilot
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"''). The etymology of the nickname is unclear: some claim it is a reference to inventor George De Beeson, who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to King George VI. First autopilots In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windscreen
The windshield (North American English) or windscreen (Commonwealth English) of an aircraft, car, bus, motorbike, truck, train, boat or streetcar is the front window, which provides visibility while protecting occupants from the elements. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame. Motorcycle windshields are often made of high-impact polycarbonate or acrylic plastic. Usage Windshields protect the vehicle's occupants from wind and flying debris such as dust, insects, and rocks, and provide an aerodynamically formed window towards the front. UV coating may be applied to screen out harmful ultraviolet radiation. However, this is usually unnecessary since most auto windshields are made from laminated safety glass. The majority of UV-B is absorbed by the glass itself, and any remaining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condensation
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition. Initiation Condensation is initiated by the formation of atomic/molecular clusters of that species within its gaseous volume—like rain drop or snow flake formation within clouds—or at the contact between such gaseous phase and a liquid or solid surface. In clouds, this can be catalyzed by water-nucleating proteins, produced by atmospheric microbes, which are capable of binding gaseous or liquid water molecules.
