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.

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).

许多滑翔伞飞行员是滑翔伞飞行员,他们在飞行中寻求更大的灵活性。许多其他飞机是新手,但对滑翔运动感兴趣,然后对纯滑翔伞飞行也很感兴趣。
BH***ower资格*适用于单人飞行。当前没有BHPA双电源认证。重申:未经BHPA资格认证的飞行员未获授权,培训或被保险与乘客飞行。
这个很贵吗?
新动力装置的成本约为3500到4,000英镑,您需要在此加上新的或二手滑翔伞的成本。您还需要飞行服,飞行靴和头盔,并且在进行过程中需要考虑购买其他设备。运行成本极低,因此动力伞可能是目前低价的动力飞行形式。
比赛怎么样?

飞行员越大,机翼的尺寸和发射所需的推力就越**多数身体健康状况良好的人都可以用脚踩动力伞,甚至有飞行员用人工关节踩脚。可能会对脚部发射的物理方面有疑问的个人可以选择在其动力伞上增加三轮车或四轮摩托车。三轮车或四轮摩托车是可以连接动力伞的平台,因此可以像常规飞机或动力降落伞一样从轮子上启动。
这项运动已经发展,现在许多高级飞行员都进行了极端的机动动作,例如侧翻,发条和翻圈。这些类型的演习存在重大危险,因为遇到的任何类型的负G都会使机翼卸载,使机翼线松弛。只有具有多年经验,训练并结合对策(例如后备降落伞)的非常先进的飞行员才能尝试这种机动。强烈建议使用备用降落伞,以防设备出现故障或飞行员犯错而造成重大伤害或死亡。
动力滑翔伞,也称为滑翔伞或PPG,是超轻型航空的一种形式,飞行员佩戴后装式马达(滑翔伞),该马达提供足够的推力以使用滑翔伞起飞。它可以由飞行员独自在静止的空气中和水平地面上发射,无需任何帮助。
This sport has evolved and now many
advanced pilots perform extreme maneuvers such as wing-overs, barrel rolls and
loops. These types of maneuvers present a significant danger as any type of
negative G's encountered will unload the wing allowing the wings lines to go
slack. Only very advanced pilots with years of experience, training and coupled
with countermeasures such as reserve parachutes should attempt such maneuvers.
A reserve parachute is a highly recommended piece of equipment which may
prevent significant injury or death in the presence of a malfunction of the
equipment or a mistake made by the pilot.
Powered paragliding, also known as
paramotoring or PPG, is a form of ultralight aviation where the pilot wears a
back-mounted motor (a paramotor) which provides enough thrust to take off using
a paraglider. It can be launched in still air, and on level ground, by the
pilot alone — no assistance is required.

Paramotor is the generic name for the
harness and propulsive portion of a powered paraglider ("PPG"). There
are two basic types of paramotors: foot launch and wheel launch.
Foot launch models consist of a frame with
harness, fuel tank, engine, and propeller. A hoop with protective netting
primarily keeps lines out of the propeller. The unit is worn like a large
backpack to which a Paraglider is attached through carabiners.
Wheel launch units either come as complete
units with their own motor, or as an add-on to a foot launch paramotor. They
usually have 3 (trike) or 4 (quad) wheels, with seats for one or two occupants.
These should not be confused with Powered Parachutes which are generally much
heavier, more powerful, and have different steering.
