41、d potentially one passenger) carried in a harness (or harnesses) connected to the wing 3.2 harness assembly composed of straps and fabric for supporting the pilot in the seated or semi-recumbent or standing position Note 1 to entry: The harness is attached to the wing via two rings or connectors; it

42、 can also be integral with the wing via risers. 3.3 emergency parachute emergency device intended to slow the descent of a paraglider pilot in the event of an incident in flight, which is deployed by the pilot by an intentional manual action Note 1 to entry: This may be unsteered or steerable. 3.4 c
