SPORT FLIGHT


SPORT FLIGHT
1.- Hot–air ballooning
This was the earliest historically document form of human flight, dating from 1783. As the name suggests, elevation is achieved by the heating of air in a balloon. The pilot then has to find winds at different altitudes that will allow him or her to go in the desired direction.
2.- Hang-gliders
The idea of flying without the propulsion of a motor is maintained in the term “ hang-gliding”. A hang-gliding is a triangular-shaped sail, whose design is based on a kite, under which a person is suspended.
3.-Sports Parachuting
This sport involves jumping out of a plane and then using a parachute to slow your descent when you approach the ground.
4.-Skydiving
This is a type of parachuting in which the objective is to spend as much time as possible falling and doing acrobatics before using the parachute. This part of the jump is known as “ free fall”. After approximately 12 seconds skydivers reach terminal velocity, about 190 km/hour.
5.-Paragliding
This term is a portmanteau: the contraction of “parachute gliding”. In this case the sportsperson is suspended below a modified parachute. This is rectangular and therefore can be manoeuvred so that she/he can change direction. As with hand-gliding and gliding, the paraglider tries to use thermal currents to stay in the air as long as possible. Experienced paragliders can stay airborne for hours.
