Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. 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. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots’ abilities to make best use of local weather conditions as well as their flying skills. Local and national competitions are organized in many countries, and there are biennial World Gliding Championships.
Powered-aircraft and winches are the two most common means of launching gliders. These and other launch methods require assistance and facilities such as airfields, tugs, and winches. These are usually provided by gliding clubs who also train new pilots and maintain high safety standards. Within ten years, it had become an international event in which the achieved durations and distances had increased greatly. Western Czechoslovakia, farther than had been thought possible. In the 1930s, gliding spread to many other countries.
In the 1936 Summer Olympics in Berlin gliding was a demonstration sport, and it was scheduled to be a full Olympic sport in the 1940 Games. A glider, the Olympia, was developed in Germany for the event, but World War II intervened. During the war, the sport of gliding in Europe was largely suspended, though several German fighter aces in the conflict, including Erich Hartmann, began their flight training in gliders. Gliding did not return to the Olympics after the war for two reasons: a shortage of gliders, and the failure to agree on a single model of competition glider. Some in the community feared doing so would hinder development of new designs. In many countries during the 1950s a large number of trained pilots wanted to continue flying.
Many were also aeronautical engineers who could design, build and maintain gliders. They started both clubs and manufacturers, many of which still exist. Since World War II it has been held every two years. There are now six classes open to both sexes, plus three classes for women and two junior classes.
Glider pilots can stay airborne for hours by flying through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy. Good gliding weather: Competitors studying cumulus humilis, which suggest active thermals and light winds. Thermals begin as bubbles of rising air that are formed on the ground through the warming of the surface by sunlight. If the air contains enough moisture, the water will condense from the rising air and form cumulus clouds. When the air has little moisture or when an inversion stops the warm air from rising high enough for the moisture to condense, thermals do not create cumulus clouds. Without clouds or dust devils to mark the thermals, thermals are not always associated with any feature on the ground.
Once a thermal is encountered, the pilot can fly in tight circles to keep the glider within the thermal, so gaining altitude before flying towards the destination or to the next thermal. Alternatively, glider pilots on cross-country flights may choose to ‘dolphin’. As it requires rising heated air, thermalling is most effective in mid-latitudes from spring through late summer. During winter the sun’s heat can only create weak thermals, but ridge and wave lift can still be used during this period. A ridge soaring pilot uses upward air movements caused when the wind blows on to the sides of hills.
It can also be augmented by thermals when the slopes also face the sun. In places where a steady wind blows, a ridge may allow virtually unlimited time aloft, although records for duration are no longer recognized because of the danger of exhaustion. The powerfully rising and sinking air in mountain waves was discovered by glider pilot, Wolf Hirth, in 1933. Gliders can sometimes climb in these waves to great altitudes, although pilots must use supplementary oxygen to avoid hypoxia. A rare wave phenomenon is known as Morning Glory, a roll cloud producing strong lift.
