The upper and the lower parts of the canopy are joined by means of
vertical ribs and form the cupola. During a flight the stopped air
rushes through the openings of the leading edge and keeps it protuberant
by the help of its static pressure. Materials of great tensile strength
are used for the production of a cupola and usually these materials
are polyamide or polyester, impregnated in order to be waterproof.
They are sewed with suitable synthetic threads.
In case of a breakdown small sport parachutes are used. The system
consists of a cupola, lines and outer and inner containers. The cupola
has an apex that softens the strike and the swinging. The lines pass
from the basis to the connecting line. The connecting line joins the
parachute and the clasp of the pack and it opens the canopy outside
the wing. The outer container holds the inner one and the parachute
and is responsible for the proper opening of the canopy. In fact,
the throwing container is an inner one but it has a handle that opens
The lines are fastened to the harness in 4 groups. There is a front
harness and a back harness, which girdles the pilot's left and right.
The pack connects the pilot with the paraglider. Different designs
influence not only the pilot's position and comfort, but also the
flight conditions. The pilot stays in the pack erect or leaning back
at a different height. The higher position gives stability, and the
lower position makes the virage easier. A crossed pack means that
the trapezium formed by the harness, the seat and the breast harness,
is stretched by extra risers. It prevents the pilot from an overturn.
Its disadvantage is in the weak reactions of the paraglider to the
An instrument that displays the altitude.
An instrument that displays the rate of descent or ascent.
An instrument that displays the wind speed.
A device used to show the direction of the wind and to some extent
the wind speed; useful for take-offs and landings.
