Noise
Paramotor noise relative to an observer
depends on distance, loudness, frequency and timbre of the power unit. Most
noise comes from the propeller and slow rpm is perceived as the quietest.
Pilots mitigate their sound impact by leaving a noise-sensitive area at low
power, keeping the farthest practical distance away, and reducing time spent
near the area.
License and training
Neither a license nor specific training is
required in the U.S., U.K. or many other countries. Where there is no specific
regulation (e.g. Mexico), paramotor flying is tolerated provided the pilots
cooperate with local officials when appropriate.[citation needed] In countries
where specific regulation exists, such as Canada, France, Italy, and South
Africa, pilots must be trained, both in flying theory and practice, by licensed
instructors. Some countries that require formal certification frequently do so
through non-government ultralight aviation organizations.
Regardless of regulations, powered
paragliding can be dangerous when practiced without proper training.

The paramotor, weighing from 45 to 90 lb
(20 to 41 kg) is supported by the pilot during takeoff. After a brief run
(typically 10 ft (3.0 m)) the wing lifts the motor and its harnessed pilot off
the ground. After takeoff, the pilot gets into the seat and sits suspended
beneath the inflated paraglider wing like a pendulum. Control is available
using brake toggles for roll and a hand-held throttle for pitch.
Military
Powered paragliding has seen a large growth
in the military including insertion of special forces soldiers and also Border
Patrol in many governments. The Lebanese Airborne regiment adopted this
technique in 2008, and the US Army, and Egyptian Army have used Paramotor Inc
FX Series units for many years.

The larger the pilot, the larger the size
of the wing and thrust required to launch. Most individuals in reasonably good
health can foot-launch a paramotor and there are even pilots with artificial
joints foot launching. Individuals that may have issues with the physical
aspect of foot launching may opt to add a trike or quad to their paramotor. A
trike or quad is a platform to which the paramotor can be attached so it can be
launched from wheels like a regular aircraft or powered parachute.
Federation Aeronautique Internationale国际航空运动联合会(FAI)(以下简称国际航联)是国际航空运动的国际组织,总部设在瑞士洛桑。1975年,国际航联在其第68届大会上决定设立悬挂滑翔委员会,动力伞和滑翔伞运动同属悬挂滑翔委员会的管理。
1999年在??举办了**届世界动力伞锦标赛,2001年在??举办了第二届世界动力伞锦标赛,2003年在??举行了第三届世界动力伞锦标赛,2005年8月18日至23日,在法国举行了第四届世界动力伞锦标赛。 还有世界航空运动会 欧洲锦标赛 2007年 月 日 至 日,在中国北京举行了第五届世界动力伞锦标赛
In many countries, including the United
States, powered paragliding is minimally regulated and requires no licence. The
ability to fly both low and slow safely, the 'open' feel, the minimal equipment
and maintenance costs, and the portability are claimed to be this type of
flying's greatest merits.[1]
Powered paragliders usually fly between 15
to 50 mph (24 to 80 km/h) at altitudes from 'foot-dragging on the water' up
about to 18,000 ft (5,500 m) or more with certain permission although most
flying is done under 500 ft (150 m) AGL.[2] Due to the paramotor's slow forward
speed and nature of a soft wing, it is not safe in high winds, turbulence, or
intense thermal activity.
