Flyback Chronograph
A flyback chronograph is a watch complication, in which the user can use a reset function without the need to first stop the chronograph, by a single press on an additional pusher at the 4 o'clock mark. In usual chronographs of the time, the user had to push three times for the same operation. First they had to stop the chronograph, then reset the hands at zero, and finally restart the chronograph in order to time the next sequence. A flyback chronograph shortens the time of operation needed to measure subsequent legs of a flight. Other names The flyback function is also known by some other names: * Retour-en-vol () * Taylor system * Permanent zero setting Overview The flyback function is a complication inspired by the need of pilots in the early 20th century, especially on shorter flights where pilots oriented themselves along highly visible geographical marks like rivers, mountains or railroad tracks. Flyback chronographs have a different layout than the usual monopusher chr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Complication (horology)
In horology, a complication is any feature of a timepiece beyond the display of hours, minutes and seconds. A timepiece indicating only hours, minutes and seconds is known as a simple movement. Common complications include date or day-of-the-week indicators, alarms, chronographs (stopwatches), and automatic winding mechanisms. Complications may be found in any clock, but they are most notable in mechanical watches where the small size makes them difficult to design and assemble. A typical date-display chronograph may have up to 250 parts, while a particularly complex watch may have a thousand or more parts. Watches with several complications are referred to as ''grandes complications.'' Types Timing * Chronograph, with a second hand that can be stopped and started to function as a stopwatch. ** Double chronograph or ''rattrapante'', multiple second hands for split-second, lap timing or timing multiple events ** Flyback chronograph, allowing rapid reset of the chronogr ...

Chronograph
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch. A basic chronograph has hour and minute hands on the main dial to tell the time, a small seconds hand to tell that the watch is running, and a seconds hand on the main dial usually equipped with a sweeping movement for precision accompanied by a minutes sub dial for the stopwatch. Another sub dial to measure the hours of the stopwatch may also be included on a chronograph. The stopwatch can be started, stopped, and reset to zero at any time by the user by operating pushers usually placed adjacent to the crown. More complex chronographs often use additional complications and can have multiple sub-dials to measure more aspects of the stopwatch such as fractions of a second as well as other helpful things such as the moon phase and the local 24-hour time. In addition, many modern chronographs include tachymeters on the bezels for rapid calculations of speed or distance. Louis M ...

History Of Aviation
The history of aviation spans over two millennia, from the earliest innovations like kites and attempts at tower jumping to Supersonic speed, supersonic and hypersonic flight in powered, heavier-than-air flight, heavier-than-air jet aircraft. Kite flying in China, dating back several hundred years BC, is considered the earliest example of man-made flight. In the 15th-century Leonardo da Vinci created several flying machine designs incorporating aeronautical concepts, but they were unworkable due to the limitations of contemporary knowledge. In the late 18th century, the Montgolfier brothers invented the Hot air balloon, hot-air balloon which soon led to manned flights. At almost the same time, the discovery of hydrogen gas led to the invention of the hydrogen balloon. Various theories in mechanics by physicists during the same period, such as fluid dynamics and Newton's laws of motion, led to the development of modern aerodynamics; most notably by Sir George Cayley. Balloons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maurice Prévost
Lucien Maurice Prévost, known as Maurice Prévost, (22 September 1887 in Reims – 27 November 1952) in Neuilly-sur-Seine) was a French pioneer aviator, best remembered for winning the first Schneider Trophy race in 1913, and the Gordon Bennett Trophy in the same year. Maurice Prévost was born in Reims at 5 rue Flodoard. He studied at the Practical School of Commerce and Industry of Reims. Joining the Betheny Deperdussin Aviation School in November 1910, Prévost rose to chief instructor. He obtained his civil pilot's license on 29 April 1911 (#475), and his military wings (#38) on 26 August 1911. He secured third place in the French military aircraft trials in November 1911 and won the altitude competition. In December 1911 he reached 10,000 feet, breaking the world altitude record with a passenger. Prévost won the first Schneider Trophy race at Monaco on 16 April 1913, and on 27 September 1913 he won the Gordon Bennett Trophy.

Wiley Post
Wiley Hardeman Post (November 22, 1898 – August 15, 1935) was an American aviator during the Aviation between the World Wars, interwar period and the first aviator, pilot to fly solo around the world. Known for his work in high-altitude flying, he helped develop one of the first pressure suits and discovered the jet stream. On August 15, 1935, he and American humorist Will Rogers were killed when his aircraft Rogers-Post Site, crashed on takeoff from a lagoon near Point Barrow in the Territory of Alaska. Post's modified Lockheed Vega aircraft, the ''Winnie Mae'', was on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center from 2003 to 2011. It is now featured in the "Time and Navigation" gallery on the second floor of the National Air and Space Museum in Washington, D.C.

Richard E
Richard is a male given name. It originates, via Old French, from compound of the words descending from Proto-Germanic language">Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include " Richie", " Dick", " Dickon", " Dickie", " Rich", " Rick", "Rico (name), Rico", " Ricky", and more. Richard is a common English (the name was introduced into England by the Normans), German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Portuguese and Spanish "Ricardo" and the Italian "Riccardo" (see comprehensive variant list below).

Double Chronograph
The Double chronograph, also known as a split-seconds chronograph, is a watch that includes two distinct stopwatch mechanisms in order to measure two separate events concurrently and/or comparatively. It is often confused with the flyback chronograph. Other names * Rattrapante chronograph () * Split-second chronograph * Split chronograph Functioning A watch with a double chronograph has two seconds hands. One hand is superimposed over the other. While one hand moves continuously, the other one can be either stopped, started or reset to zero. The first push releases both hands. While one continues registering the time, the other hand can be repeatedly stopped. In order to stop and bring both hands to zero a watch has a return pusher. The position of the pusher, controlling the split-seconds function is usually at either 10 or 8 o'clock. Brief history The double chronograph was previously called Fly-back second, but nowadays 'Fly-back second' relates to a chronograph where the ...

Watches
A watch is a Clock, timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain. A stopwatch is a type of watch that measures intervals of time. During most of their history, beginning in the 16th century, watches were mechanical devices, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are known as ''mechanical watches''. In the 1960s the electronic quartz clock, ''quartz watch'' was invented, powered by a Battery (electricity), battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the Quartz crisis, quartz revolution (or the quartz crisis in Switzerla ...

Clocks
A clock or chronometer is a device that measures and displays time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology (the study of timekeeping), the term ''clock'' was us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
