南宁重量动力伞使用方法
For a pilot to get through most
organizations' full pilot syllabus requires between 5 and 15 days which, due to
weather, may include far more calendar time. A number of techniques are
employed for teaching, although most include getting the student familiar with
handling the wing either on the ground, via towing, small hills, or on tandem
flights.
With special gear it is possible to take a
passenger (tandem), but most countries, including the U.S., require some form
of certification to do so.

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.

动力伞发动机多数是两冲程机器,加普通汽油,要掺混两冲全合成机油,比例一般30:1或40:1。油耗根据发动机排量大小而不同,约为每小时4升。动力伞的飞行高度取决于飞行环境和器材的性能,特殊比如转子发动机的动力伞,曾经飞越过珠峰。要问能飞多远,要看油量,风的大小,是顺风,还是逆风,静风时,一般时速45公里。顺风能上60公里,逆风会在45公里以下,甚至悬停倒退。动力伞不着陆飞行的世界纪录已经超过1000公里,根据中国民航法的规定,115公斤以下的飞行器不强制要求飞行员拥有飞行执照,美国,英国,法国等航空大国的法规在这点上和中国一样的,动力伞属于115公斤以下的飞行器,所以不强制要求飞行员拥有飞行执照。动力伞飞行分运动员赛事飞行和爱好者休闲飞行,做一名动力伞运动员需要有运动证书,才有参赛的资质。运动员证书由中国航空运动协会悬挂滑翔及滑翔伞委员会颁发。作为一名爱好者飞行虽然不强制要求飞行执照, 系统的理论学习和地面操作练习是必须的,并且要远离机场,居民中心,飞机起降航线,军队,边境等重要地区。随着国家低空逐渐开放,相应的国家有关飞行规定,具体可参照中国民用航空器飞行规则等有关内容。
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]
A powered paraglider trike landing
Lightweight carts or "trikes"
(called "quads" if they have four wheels) can also be mounted on powered
paragliders for those who prefer not to, or are unable to, foot launch. Some
are permanent units.
In the United States, if the aircraft meets
the ultralight definitions, no license is required. In the UK, trike-mounted
paramotors are still classified as 'self-propelled hang-gliders' if the
"performance of the aircraft remains equivalent to one that can be
foot-launched." [7]. However, even in these countries, if the machine has
two seats it is no longer an ultralight. In the US such a craft would be governed
under the Sport Pilot rules and regulated as a light sport aircraft powered
parachute which requires an aircraft N-number and pilots must be licensed.
