Regulations
In most countries, paramotor pilots operate
under simple rules that spare them certification requirements for pilot and
gear. Those laws, however, limit where they can fly—specifying that pilots
avoid congested areas and larger airports to minimize risk to other people or
aircraft. U.S. pilots operate under Federal Aviation Administration regulation
Part 103.
Associations
In the U.S., the sport is represented
primarily by the US Powered Paragliding Association (USPPA)[note 1] which also
holds an exemption allowing two-place training by appropriately certified
tandem instructors. The US Ultralight Association (USUA) and Aero Sports
Connections (ASC) also offer some support.
Instructors in the U.S. are primarily
represented and certified by the United States Powered Paragliding
Association(USPPA). Other organizations include the Professional Association of
Powered Paragliding Instructors (***PI).

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.

Paramotoring is Paragliding with an
auxiliary motor attached to the pilot. The CAA has defined this recently
legitimized form of powered flight as a foot launched self-propelled Hang
glider (SPHG). This does not mean that Paramotors are deregulated, They still
have to comply with all U.K. aviation law, and some specific restrictions of
their own (Click Image to read PDF syllabus here). However these small aircraft
allow you the freedom of the skies, with less red tape and costs than any other
powered aircraft. With the ability to be able to take off from a small flat
field and climb a Paramotor can fly just like any other aircraft. Para motors
can have enough fuel to fly for between 2.5 - 4 hrs, can climb to around 500'
per minute and fly at between 25 to 45 mph. At Axis training we have a lot of
experience with Paramotoring, our first flights were in 1993 on Scobojets, and
we have learned a lot and developed great teaching techniques ever since. We
prefer if possible to have most of our Paramotorists, learn as much on the
paraglider as they can prior to flying a Paramotor. This helps them become much
better, safer and more confident pilots.
飛行員通過(guò)手持節(jié)氣門(mén)控制推力,并使用機(jī)翼剎車(chē)肘節(jié)或stabilo轉(zhuǎn)向,重量轉(zhuǎn)移或這三者的組合進(jìn)行轉(zhuǎn)向。它與滑翔傘相同,只是它是動(dòng)力驅(qū)動(dòng)的,因此不需要使用海拔或熱量來(lái)提升。與自由飛行的“滑翔傘”機(jī)翼相比,動(dòng)力傘的機(jī)翼已經(jīng)專門(mén)為動(dòng)力推進(jìn)而發(fā)展。這樣的機(jī)翼通常被設(shè)計(jì)用于更高的速度,并且可以結(jié)合“反射”輪廓以有助于俯仰的穩(wěn)定性,該想法取自1980年代的懸掛式滑翔機(jī)。動(dòng)力傘的機(jī)翼通常使用微調(diào)器來(lái)調(diào)節(jié)機(jī)翼的迎角,以使其減速或加速飛行。修剪允許飛行員達(dá)到比較大速度,修剪允許允許針對(duì)發(fā)射和降落進(jìn)行優(yōu)化的較慢速度。
滑行**困難的方面是控制地面上的機(jī)翼(滑翔傘)。該控制既在發(fā)射期間又在著陸時(shí)進(jìn)行。成為滑翔傘飛行員的初步培訓(xùn)包括在沒(méi)有馬達(dá)的情況下管理地面上的機(jī)翼。此過(guò)程稱為工具包,是該過(guò)程中**復(fù)雜,**重要的步驟。一旦掌握了地面上的機(jī)翼套件,便將電動(dòng)機(jī)添加到該過(guò)程中,以便在練習(xí)中使用附帶動(dòng)力的重量。典型的動(dòng)力傘平均重約50磅。
(23公斤),某些型號(hào)的重量為40磅。
(18公斤),某些型號(hào)的重量高達(dá)75磅。
(34公斤)。動(dòng)力傘翼和發(fā)動(dòng)機(jī)的尺寸取決于飛行員的體重。
中國(guó)航協(xié)懸掛滑翔委員會(huì)在社會(huì)贊助和支持下,先后在北京、上海、天津、廣州、深圳、武漢、成都、西安、青島、大連、哈爾濱、沈陽(yáng)、石家莊、鄭州、南昌、南京、杭州、福州、廈門(mén)等城市組織了多次動(dòng)力傘巡回賽、動(dòng)力傘邀請(qǐng)賽和全國(guó)錦標(biāo)賽并組織了多次動(dòng)力傘飛行表演,每次的賽事和活動(dòng)都在社會(huì)上產(chǎn)生了巨大影響,從而推動(dòng)了我國(guó)動(dòng)力傘運(yùn)動(dòng)的發(fā)展。1997年,中國(guó)香港回歸之際,成功舉辦了中國(guó)香港至北京動(dòng)力傘拉力賽,2004年,“海爾杯”動(dòng)力傘巡回賽,歷經(jīng)三個(gè)多月十八個(gè)城市,到場(chǎng)觀眾超過(guò)了20萬(wàn)人,**電視臺(tái)國(guó)際頻道對(duì)賽事進(jìn)行了全程報(bào)道并制作了多集專題片。2005年,在上海成功舉辦了有七個(gè)國(guó)家和地區(qū)45名運(yùn)動(dòng)員參加的國(guó)際動(dòng)力傘邀請(qǐng)賽,特別邀請(qǐng)了國(guó)際航聯(lián)的官員和裁判,得到了國(guó)際**們的充分肯定。中國(guó)航協(xié)也組織參加了多次在國(guó)外舉行的世界性比賽, 2005年8月,中國(guó)動(dòng)力傘**隊(duì)3名運(yùn)動(dòng)員,參加了在法國(guó)舉辦的世界動(dòng)力傘錦標(biāo)賽。2006年,再次得到國(guó)際**企業(yè)的贊助和支持,成功在五個(gè)城市舉行了“豐田銳志杯”動(dòng)力傘巡回賽暨全國(guó)錦標(biāo)賽。由于國(guó)內(nèi)舉辦各種動(dòng)力傘賽事和活動(dòng)的巨大成功,得到了國(guó)際航聯(lián)的高度重視。嘉興學(xué)習(xí)動(dòng)力傘

動(dòng)力滑翔傘可用作在困難地形中的陸地車(chē)輛的替代品。在春季某些地區(qū),當(dāng)海洋或湖泊仍然結(jié)冰,但冰已經(jīng)開(kāi)始融化時(shí),水將無(wú)法行走,滑行或行駛,也無(wú)法乘船航行。在這種情況下,水上直升機(jī),氣墊船旅行方式。此外,如果像沼澤地一樣,地形被小而淺的湖泊和海灣所破壞,即使在良好的條件下也可能難以導(dǎo)航。觀察和計(jì)數(shù)受保護(hù)物種,例如在這種情況下,Saimaa環(huán)型密封已經(jīng)使用動(dòng)力滑翔傘進(jìn)行了。
已證明的另一種用途是馴鹿放牧。盡管凍原是開(kāi)闊的地形,但沒(méi)有道路,地形仍然不平坦。可以使用動(dòng)力降落傘代替雪地摩托或摩托車(chē)。
安全法規(guī)
研究估計(jì),這項(xiàng)活動(dòng)(每項(xiàng)活動(dòng))比騎摩托車(chē)稍微安全一些,并且比坐汽車(chē)更危險(xiǎn)。[3]嚴(yán)重傷害的**可能原因是身體與旋轉(zhuǎn)的螺旋槳接觸。下一個(gè)**可能造成傷害的原因是飛入降落區(qū)以外的地方。[4]一些飛行員攜帶備用降落傘,設(shè)計(jì)用于在15英尺(50英尺)的范圍內(nèi)打開(kāi)。
這些飛機(jī)缺乏既定的設(shè)計(jì)標(biāo)準(zhǔn),導(dǎo)致英國(guó)查處在2007年得出結(jié)論:“只有在確定了實(shí)際吊運(yùn)質(zhì)量的單個(gè)線束/機(jī)翼組合的精確儲(chǔ)備系數(shù)時(shí),才采用適合于機(jī)動(dòng)的負(fù)荷系數(shù)。進(jìn)行,這些飛機(jī)是否可以被認(rèn)為在結(jié)構(gòu)上安全” [5]
