The paramotor, weighing from 45 to 90 lb
(20 to 41 kg) is supported by the pilot during takeoff，动力伞. 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.

Safety and regulations
Research estimates that the activity is
slightly safer (per event) than riding motorcycles and more dangerous than
riding in cars.[3] The most likely cause of serious injury is body contact with
a spinning propeller. The next most likely cause of injury is flying into
something other than the landing zone.[4] Some pilots carry a reserve parachute
designed to open in as little as 50 ft (15 m).
The lack of established design criteria for
these aircraft led the British Air Accidents Investigation Branch to conclude
in 2007 that "Only when precise reserve factors have been established for
individual harness/wing combinations carrying realistic suspended masses, at
load factors appropriate to the maneuvers to be carried out, can these aircraft
be considered to be structurally safe"[5]
中国航协悬挂滑翔委员会在社会赞助和支持下，先后在北京、上海、天津、广州、深圳、武汉、成都、西安、青岛、大连、哈尔滨、沈阳、石家庄、郑州、南昌、南京、杭州、福州、厦门等城市组织了多次动力伞巡回赛、动力伞邀请赛和全国锦标赛并组织了多次动力伞飞行表演，每次的赛事和活动都在社会上产生了巨大影响，从而推动了我国动力伞运动的发展。1997年，中国香港回归之际，成功举办了中国香港至北京动力伞拉力赛，2004年，“海尔杯”动力伞巡回赛，历经三个多月十八个城市，到场观众超过了20万人，**电视台国际频道对赛事进行了全程报道并制作了多集专题片。2005年，在上海成功举办了有七个国家和地区45名运动员参加的国际动力伞邀请赛，特别邀请了国际航联的官员和裁判，得到了国际**们的充分肯定。中国航协也组织参加了多次在国外举行的世界性比赛， 2005年8月，中国动力伞**队3名运动员，参加了在法国举办的世界动力伞锦标赛。2006年，再次得到国际**企业的赞助和支持，成功在五个城市举行了“丰田锐志杯”动力伞巡回赛暨全国锦标赛。由于国内举办各种动力伞赛事和活动的巨大成功，得到了国际航联的高度重视。

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.
