Gliding
Gliding is a recreational activity and competitive air sports, air sport in which pilots fly glider aircraft, unpowered aircraft known as Glider (sailplane), gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: Ridge Lift, ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ann Welch
Ann Courtenay Welch OBE, née Edmonds, (20 May 1917 – 5 December 2002) was a pilot who received the Gold Air Medal from Fédération Aéronautique Internationale (FAI) for her contributions to the development of four air sports - gliding, hang gliding, paragliding and microlight flying. She flew as a ferry pilot in the Air Transport Auxiliary during the Second World War. Early life ''''Ann Courtney Edmonds was born in London, the daughter of a railway engineer. As a child, she kept a diary listing every aeroplane that flew over the house. She first flew with Alan Cobham in 1930. After she had acquired a motorbike to visit the local aerodrome, she learned to fly, earning her pilot's licence in 1934 one month after her seventeenth birthday. From an early age she excelled in drawing and painting, and was a painter of note. Gliding activity She started gliding in 1937 and attended an Anglo-German Fellowship Camp at the London Gliding Club meeting Wolf Hirth and Hanna Reit ...

Sigma (sailplane)
The Sigma is an experimental glider developed in Britain from 1966 by a team led by Nicholas Goodhart. After disappointing performance during flight testing the Sigma was passed on to a Canadian group which carried out modifications, making the Sigma more competitive. Design and development Designed to compete in the 1970 World Gliding Championships, the team aimed to develop a wing that would climb well through a high lift coefficient and a large wing area, but equally had the "maximum possible reduction of area for cruise at low lift coefficients". At the same time for the minimum possible drag they aimed for "extensive" laminar flow. To achieve this they employed flaps that would alter both wing area and wing camber. Based on analysis of the nature of thermals encountered in cross-country flying, they reasoned that by having a slow turning circle, their sailplane could stay close to the central (and strongest) part of the thermal and gain maximum benefit. Its unusual feat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variometer
In aviation, a variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the aviator, pilot of the rate of descent or climb.Federal Aviation Administration, ''Glider Flying Handbook'', Skyhorse Publishing Inc., 2007 pages 4-7 and 4-8 It can be calibrated in metres per second, feet per minute (1 ft/min = 0.00508 m/s) or knot (unit), knots (1 kn ≈ 0.514 m/s), depending on country and type of aircraft. It is typically connected to the aircraft's external static pressure source. In powered flight, the pilot makes frequent use of the VSI to ascertain that level flight is being maintained, especially during turning maneuvers. In gliding, the instrument is used almost continuously during normal flight, often with an audible output, to inform the pilot of Atmospheric convection, rising or ...

Organisation Scientifique Et Technique Du Vol à Voile
Organisation Scientifique et Technique du Vol à Voile (OSTIV) is a body associated with the FAI Gliding Commission (IGC). The FAI IGC oversees the sport of gliding worldwide and is a department of the Fédération Aéronautique Internationale (FAI). In 1930 the first international soaring organization, ISTUS, (Internationale Studienkommission für den motorlosen Flug) was formed with the objective of the furtherance of development of soaring in science and technical aspects by "exchanging experience and friendly cooperation among the specialists and pilots of all nations engaged in soaring". This objective was continued after World War II by the formation of OSTIV. OSTIV's aim is also the furtherance of the technical development of soaring by the sharing of experience by glider manufacturers and glider pilots. It was formed as the successor of ISTUS on 27 July 1948 at Samedan, Switzerland. Its sections include the Meterorological Panel, the Sailplane Development Panel and the Tr ...

British Gliding Association
The British Gliding Association (BGA) is the governing body for gliding in the United Kingdom. Gliding in the United Kingdom operates through 80 gliding clubs (both civilian and service) which have 2,310 gliders and 9,462 full flying members (including service personnel), though a further 17,000 people have gliding air-experience flights each year. History A gliding event first occurred in the UK on a hill at Itford in East Sussex in 1922. The meeting was largely a publicity stunt by the ''Daily Mail'' newspaper which had offered a prize of one thousand pounds for the longest flight. However little gliding happened in the UK for several years after until reports of long flights in thunderstorms in Germany appeared in ''The Aeroplane'' magazine. Douglas Culver suggested a lunch meeting at the Comedy Restaurant in London on 4 December 1929 for anybody who was interested. Fifty-six people attended and a committee was formed. Shortly after the BGA was founded to start the spor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FAI Gliding Commission
The International Gliding Commission (IGC) is the international governing body for the sport of gliding. It is governed by meetings of delegates from national gliding associations. It is one of several Air Sport Commissions (ASC) of the Fédération Aéronautique Internationale (FAI), or "World Air Sports Federation". FAI is the world body for sporting aviation and the certification of world records for aeronautics and astronautics and was founded in 1905. When the IGC was founded in 1932, it was called CIVV (Commission Internationale de Vol à Voile) and has also been called CVSM (Commission de Vol Sans Moteur). It is the FAI commission responsible for the international competitions, records and badges that apply to gliders and motor gliders. The term "sailplanes" is sometimes used. Hang gliders and paragliders have a separate body called the FAI CIVL Commission, which stands for "Commission Internationale de Vol Libre". The World Gliding Championships are organised every tw ...
