In many countries, including the United
States, powered paragliding is minimally regulated and requires no licence. The
ability to fly both low and slow safely, the 'open' feel, the minimal equipment
and maintenance costs, and the portability are claimed to be this type of
flying's greatest merits.[1]
Powered paragliders usually fly between 15
to 50 mph (24 to 80 km/h) at altitudes from 'foot-dragging on the water' up
about to 18,000 ft (5,500 m) or more with certain permission although most
flying is done under 500 ft (150 m) AGL.[2] Due to the paramotor's slow forward
speed and nature of a soft wing, it is not safe in high winds, turbulence, or
intense thermal activity.

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.

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.

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.

這個(gè)很貴嗎?
新動(dòng)力裝置的成本約為3500到4,000英鎊,您需要在此加上新的或二手滑翔傘的成本。您還需要飛行服,飛行靴和頭盔,并且在進(jìn)行過(guò)程中需要考慮購(gòu)買(mǎi)其他設(shè)備。運(yùn)行成本極低,因此動(dòng)力傘可能是目前低價(jià)的動(dòng)力飛行形式。
