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]

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.

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.
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.
Paramotor (動(dòng)力傘) 源自英文
Paragliding(滑翔傘)和motor(摩托)。顧名思義,動(dòng)力傘是在滑翔傘上加配了動(dòng)力裝置。1978年,法國(guó)登山家貝登先生成明了滑翔傘,使人類翱翔藍(lán)天的夢(mèng)想得以實(shí)現(xiàn)。然而,人們?cè)跉g喜之余發(fā)現(xiàn),滑翔傘的飛翔與夢(mèng)想中的自由飛翔仍有距離,**主要的一點(diǎn)就是不能在平地自由起降,起飛受山坡條件的制約,更使沒(méi)有山峰地區(qū)的飛行愛(ài)好者感到難受。1984年,一群充滿浪漫與幻想的法國(guó)滑翔傘愛(ài)好者,給滑翔傘加掛了一個(gè)小型發(fā)動(dòng)機(jī),利用發(fā)動(dòng)機(jī)帶動(dòng)螺旋槳的推力和滑翔傘傘翼的升力,使平地“自由起降”不再成為問(wèn)題,達(dá)到了自己飛得更高、更遠(yuǎn),留空時(shí)間更長(zhǎng)的目的,從而創(chuàng)立了這項(xiàng)新興的航空體育項(xiàng)目。 金華維修動(dòng)力傘使用方法

To learn Paramotoring we believe that there
are no shortcuts. Do not believe anyone who tells you that you need no
training, or just a couple of days! They are probably just trying to sell you
some equipment! Any form of aviation can kill if practiced in error. Knowledge
is the key to safe flight! We now have a new syllabus from the BHPA with a
first step "restricted qualification" BHPA CP POWER rating, which can
be achieved in around 8 days or so of training. This new easier to obtain
rating means you don't have to take a full paragliding course Your first big
flights and circuits will be solo on the Paramotor. The restricted
qualification will allow you to fly from your "own" field. If you
wish to fly Cross Country and further afield, then you will need to continue to
the Full BHPA "Pilot" rating which may take another 1 day. At Axis we
are a BHPA registered school, and we are covered by third party Insurance to
teach you. You will also be Insured as the pilot!
