Mid-air Collision
In aviation, a mid-air collision is an aviation accident, accident in which two or more aircraft come into unplanned contact during flight. The potential for a mid-air collision is increased by Aviation communication, miscommunication, mistrust, error in Air navigation, navigation, deviations from flight plans, lack of situational awareness, and the lack of Traffic collision avoidance system, collision-avoidance systems. Although a rare occurrence in general due to the vastness of open space available, collisions often happen near or at airports, where large volumes of aircraft are spaced more closely than in general flight. First recorded collision The first recorded collision between aircraft occurred at the "Milano Circuito Aereo Internazionale" meeting held between 24 September and 3 October 1910 in Milan, Italy. On 3 October, Frenchman René Thomas (racing driver), René Thomas, flying the Antoinette IV monoplane, collided with British Army Captain Bertram Dickson by r ...

Decapitation
Decapitation is the total separation of the head from the body. Such an injury is invariably fatal to humans and all vertebrate animals, since it deprives the brain of oxygenated blood by way of severing through the jugular vein and common carotid artery, while all other organs are deprived of the autonomic nervous system, involuntary functions that are needed for the body to function. The term beheading refers to the act of deliberately decapitating a person, either as a means of murder or as an capital punishment, execution; it may be performed with an axe, sword, or knife, or by mechanical means such as a guillotine. An executioner who carries out executions by beheading is sometimes called a headsman. Accidental decapitation can be the result of an explosion, a car or industrial accident, improperly administered execution by hanging or other violent injury. The national laws of Saudi Arabia and Yemen permit beheading. Under Sharia in Nigeria, Sharia, which exclusively appl ...

Horizontal Stabilizer
A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail ( empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 s ...
