**History and Development of Gliding:**
– Gliding emerged post-WWI due to aircraft restrictions in Germany.
– German focus on glider development in the 1920s and 1930s.
– First German gliding competition in 1920; demonstration sport in 1936 Olympics.
– Spread of gliding to many countries in the 1930s.

**Types of Lift in Gliding:**
– Soaring methods like thermals, ridge lift, and wave lift.
– Ridge lift allows climbs up to 600 meters; thermals can exceed 3,000 meters.
– Gliders reached altitudes of 23,202 meters using wave lift.
– Formation and characteristics of thermals with circling techniques.

**Launch Methods and Safety Standards:**
– Common launch methods using powered aircraft and winches.
– Gliding clubs provide assistance and facilities for launching.
– Safety standards maintained by clubs and national associations.
– Oversight of safety standards by governmental bodies in most countries.

**Gliding Competitions and Techniques:**
– Gliding competitions test pilot skills in utilizing weather conditions.
– Local, national, and World Gliding Championships held biennially.
– Techniques for maximizing speed and efficiency in competitions.
– Records set, technological advancements, and strategies for cross-country flights.

**Challenges, Hazards, and Regulation in Gliding:**
– Challenges faced by the gliding movement such as time constraints and airspace limitations.
– Hazards like fatal accidents, mid-air collisions, and compliance with safety rules.
– Training and regulation through national laws and gliding associations.
– Annual inspections, payload limits, and examinations for pilots’ certification.

Gliding (Wikipedia)

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. 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, 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 1,000 kilometres (621 mi) are achieved.

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. Techniques to maximize a glider's speed around the day's task in a competition have been developed, including the optimum speed to fly, navigation using GPS and the carrying of water ballast. If the weather deteriorates pilots are sometimes unable to complete a cross-country flight. Consequently, they may need to land elsewhere, perhaps in a field, but motorglider pilots can avoid this by starting an engine.

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. Although in most countries the standards of safety of the pilots and the aircraft are the responsibility of governmental bodies, the clubs and sometimes national gliding associations often have delegated authority.
