Powered paragliders are useful as
replacements for terrestrial vehicles in difficult terrain. In some areas
during the spring when the sea or lakes are still frozen but the ice has begun
melting, the waters cannot be walked, skied, or driven on and cannot be
navigated by boat. Hydrocopters, hovercraft, and aircraft are the only ways to
travel in such conditions. Furthermore, if the landscape is fractured by small
and shallow lakes and bays, as in swamplands, it may be difficult to navigate
even in good conditions. Observation and counting of protected species, e.g.
Saimaa ringed seal, in such conditions has been conducted using a powered
paraglider.
Another use that has been demonstrated is
the herding of reindeer. Although the tundra is open terrain, there are no
roads and the terrain is still uneven. A powered parachute can be used instead
of a snowmobile or a motorcycle.

The pilot controls thrust via a hand-held
throttle and steers using the wings brake toggles or stabilo steering, weight
shifting or a combination of the three. It is identical to Paragliding except
it is powered so the use of an elevation or thermals to ascend are not
required. Paramotor wings have evolved specifically for use with power
propulsion, as compared with free flight 'paraglider' wings. Such wings are
typically designed for a higher speed and may incorporate a "reflex"
profile to aid stability in pitch, an idea taken from hang gliders of the
1980s. Paramotor wings typically use trimmers to adjust the Angle of Attack of
the wing to either slow it down or speed it up in flight. Trimmed out allows
the pilot to achieve maximum speed, while trimmed in allows for slower speeds
optimized for launching and landing.

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.
在包括美國(guó)在內(nèi)的許多國(guó)家/地區(qū)，對(duì)動(dòng)力滑翔傘的管制很少，不需要執(zhí)照。這種飛行的比較大優(yōu)點(diǎn)是能夠安全低空飛行和緩慢飛行，“開(kāi)放”的感覺(jué)，**少的設(shè)備和維護(hù)成本以及便攜性。[1]
動(dòng)力滑翔傘通常在15到50英里/小時(shí)（24到80公里/小時(shí)）的飛行速度下，從“在水上拖曳腳踏”到大約18,000英尺（5,500 m）或更高的高度，盡管大多數(shù)飛行是在500英尺以下完成的（150 m）AGL。[2]由于動(dòng)力傘的慢速前進(jìn)速度和柔和的機(jī)翼特性，在大風(fēng)，湍流或激烈的熱活動(dòng)中它并不安全。
起飛期間，飛行員會(huì)支撐重達(dá)45至90磅（20至41千克）的動(dòng)力傘。短暫運(yùn)行（通常為10英尺（3.0 m））后，機(jī)翼將電動(dòng)機(jī)及其吊帶飛行員抬離地面。起飛后，飛行員進(jìn)入座位并像鐘擺一樣懸掛在充氣的滑翔傘機(jī)翼下方。可使用制動(dòng)撥動(dòng)（用于橫滾）和手持節(jié)氣門(mén)（用于俯仰）進(jìn)行控制。
動(dòng)力滑翔傘在**中得到了巨大的發(fā)展，包括在許多**中部署了特種**士兵以及邊境巡邏隊(duì)。黎巴嫩空降團(tuán)于2008年采用了這種技術(shù)，美國(guó)陸軍和埃及陸軍已經(jīng)使用了Paramotor Inc FX系列裝置多年。
在開(kāi)始培訓(xùn)時(shí)，您將開(kāi)始意識(shí)到這項(xiàng)運(yùn)動(dòng)涉及多少，它不是空中摩托車(chē)或水上摩托車(chē)，因此了解飛***象學(xué)至關(guān)重要。
滑翔傘（也稱(chēng)為動(dòng)力滑翔傘）將滑翔傘的易飛特性與動(dòng)力飛行的自主性和范圍結(jié)合在一起。
動(dòng)力傘（由Paul Bailey提供）
動(dòng)力傘相對(duì)易于學(xué)習(xí)飛行，并且可以腳踩啟動(dòng)，只要有您的許可，并且只要沒(méi)有樹(shù)，牲畜或旁觀者的危害，它們都可以在空曠的平坦場(chǎng)地起飛。
（飛機(jī)場(chǎng)當(dāng)然是理想的）無(wú)需找到面向風(fēng)的小山地，甚至無(wú)需等待風(fēng)吹來(lái)。
它們可以快速，輕松地進(jìn)行索具和索具的拆卸，一旦拆除，就可以放在汽車(chē)的后備箱中，也可以作為手提行李帶到異國(guó)的地點(diǎn)。
動(dòng)力傘到底是什么？
這是所有動(dòng)力飛機(jī)中**簡(jiǎn)單的飛機(jī)，由驅(qū)動(dòng)螺旋槳的小型電動(dòng)機(jī)組成，螺旋槳像背包一樣穿著在滑翔傘機(jī)翼下方，并提供起飛，爬升和保持水平飛行的推力。
一旦升空后，滑翔傘就可用于沿著下方行駛并觀察周?chē)氖澜?，或者在條件允許的情況下，以熱升力飆升以進(jìn)行長(zhǎng)時(shí)間的越野飛行。
電動(dòng)機(jī)可以在空中停止和重新啟動(dòng)，其中許多電動(dòng)機(jī)具有電啟動(dòng)器，使飛行員能夠使其飛行適應(yīng)當(dāng)前條件。

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.
