噪声

相对于观察者的动力伞噪声取决于动力装置的距离，响度，频率和音质。大部分噪音来自螺旋桨，而缓慢的转速被认为是**安静的。飞行员可以通过将噪声敏感的区域保持在低功率状态来减轻其声音影响，将实际距离保持在**远的位置，并减少在该区域附近所花费的时间。

执照和培训

在美国，英国或许多其他国家，既不需要许可证，也不需要特定的培训。在没有特别规定的地方（例如墨西哥），只要飞行员在适当的情况下与当地官员合作，就可以容许滑翔伞飞行。[需要引用]在存在特别规定的国家（例如加拿**国，意大利和南非），飞行员必须由执照的教练进行飞行理论和实践方面的培训。一些需要正式认证的国家经常通过非**的超轻航空组织进行认证。

无论法规如何，如果没有经过适当培训，进行动力滑翔伞运动都是很危险的。

对于飞行员来说，要通过大多数组织的完整飞行员教学大纲，需要5到15天的时间，由于天气原因，这可能需要更长的日历时间。教学中使用了许多技巧，尽管大多数技巧包括让学生熟悉在地面上，通过牵引，小山丘或串列飞行时如何操纵机翼。

借助特殊装备，可以乘搭乘客（双人），但是大多数国家（包括美国）都需要某种形式的证明。

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 (动力伞) 源自英文

Paragliding（滑翔伞）和motor（摩托）。顾名思义，动力伞是在滑翔伞上加配了动力装置。1978年，法国登山家贝登先生成明了滑翔伞，使人类翱翔蓝天的梦想得以实现。然而，人们在欢喜之余发现，滑翔伞的飞翔与梦想中的自由飞翔仍有距离，**主要的一点就是不能在平地自由起降，起飞受山坡条件的制约，更使没有山峰地区的飞行爱好者感到难受。1984年，一群充满浪漫与幻想的法国滑翔伞爱好者，给滑翔伞加挂了一个小型发动机，利用发动机带动螺旋桨的推力和滑翔伞伞翼的升力，使平地“自由起降”不再成为问题，达到了自己飞得更高、更远，留空时间更长的目的，从而创立了这项新兴的航空体育项目。

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]

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.

The most difficult aspect of paramotoring

is controlling the wing (paraglider) on the ground. This control is both during

launch and upon landing. Initial training in becoming a paramotor pilot

involves managing the wing in the air from the ground without the motor. This

process is called kiting and is the most complicated and important step in the

process. Once kiting the wing on the ground is mastered then the motor is added

to the process to practice with the weight of the paramotor included. A typical

paramotor will weigh on average around 50 lbs. (23 kg) with some models as

light at 40 lbs. (18 kg) and some models as high as 75 lbs. (34 kg.) The size

of the paramotor wing and engine are dependent on the weight of the pilot.
