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。

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.

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.
To learn Paramotoring we believe that there
are no shortcuts. Do not believe anyone who tells you that you need no
training, or just a couple of days! They are probably just trying to sell you
some equipment! Any form of aviation can kill if practiced in error. Knowledge
is the key to safe flight! We now have a new syllabus from the BHPA with a
first step "restricted qualification" BHPA CP POWER rating, which can
be achieved in around 8 days or so of training. This new easier to obtain
rating means you don't have to take a full paragliding course Your first big
flights and circuits will be solo on the Paramotor. The restricted
qualification will allow you to fly from your "own" field. If you
wish to fly Cross Country and further afield, then you will need to continue to
the Full BHPA "Pilot" rating which may take another 1 day. At Axis we
are a BHPA registered school, and we are covered by third party Insurance to
teach you. You will also be Insured as the pilot!
A powered paraglider differs from a powered
parachute (PPC) primarily in size, power, control method, and number of
occupants. Powered paragliders are smaller, use more efficient (but more
difficult to manage) paraglider wings, and steer with brake toggles like sport
parachutists. Powered parachutes typically use easier-to-manage but less
efficient wings, have larger engines, steer with their feet, and may be able to
take along passengers. There are exceptions; a growing number of powered
parachutes use elliptical wings, some use hand controls, and many are light
single seat aircraft that meet FAA Part 103 requirements.

The term was first used by Englishman Mike
Byrne in 1980[1] and popularized in France around 1986 when La Mouette began
adapting power to the then-new paraglider wings.
Power plants are almost exclusively small
two-stroke internal combustion engines, between 80 cc and 350 cc, that burn a
mixture of gasoline and oil. These engines are favored for their quick high
r.p.m. thrust and low weight, using approximately 3.7 litres (1 US Gal.) of
fuel per hour depending on paraglider efficiency, the weight of unit plus
pilot, and flying weather conditions. At least one manufacturer is producing a
4-stroke model favored for its strong lower r.p.m. thrust and better fuel
efficiency. Electrically powered units also exist, though flight duration is
considerably limited on the battery's electrical capacity. Csaba Lemak created
the first electric PPG, flying it first on 13 June 2006.[2][3] Wankel rotary
engined paramotors are also available, but rare.
