According to a
general practice among manufacturers, hang gliders come under three categories.
The gliders of the first
class are essentially directed towards instruction on a training slope and the first
practice of high flights. The performance is usually modest but handling is relatively
The gliders of the second class are meant for pilots who have already a firm experience
through about one-year of regular practice. To handle these gliders require more skill and
the performance is already adequate to tackle cross country flights.
The gliders of the third class require a high degree of precision in handling, an
excellent knowledge of aerology and several years experience. These are the high
performance machines, which open the doors to the ultimate cross-country flights.
