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.

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.
规章制度
在大多数国家/地区中,动力伞驾驶员均遵循简单的规则进行操作,从而免除了飞行员和装备的认证要求。但是,这些法律限制了其飞行的范围-说明飞行员要避开拥挤的区域和较大的机场,以很大程度地降低对他人或飞机的风险。美国飞行员根据联邦航空管理局法规第103部分进行操作。
社团协会
在美国,这项运动主要由美国动力滑翔伞协会(USPPA)代表[注1],该协会也享有一项豁免,允许由经过适当认证的双人教练进行两次训练。美国超轻型飞机协会(USUA)和航空运动连接公司(ASC)也提供了一些支持。
美国的讲师主要由美国动力滑翔伞协会(USPPA)代表和认证。其他组织包括动力滑翔伞教练专业协会(PAPPI)。
在英国,这项运动由英国滑翔伞和滑翔伞协会代表,而非正式地由Paramotor俱乐部代表。[6]

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.

长江航道上的航标灯分红色和绿色的代表什么意思?绿色的是“绿浮”,又叫“黑浮”,就是右侧标,进长江要放在船的右舷通过,出长江时要放在船舶左舷通过;红色的是“红浮”,是左侧标,进长江的时候要放在船的左舷通过,出长江要放在船的右舷通过。内河助航标志,是指为了便利航行而设置的视觉、音响和无线电助航设施,帮助船舶安全、简称内河航标。通过合理配布内河航标航道灯,可以标示内河航道的方向、界限与碍航物,揭示有关航道信息,为船舶指示出经济、安全的航道。航标灯可以提高船只的竞技水平和成绩。上海GPRS航标灯根据功能不同,航标灯可以分为导航标志灯、防撞标志灯、岸边标志灯、港湾标志灯等多个分类。其中导航标志灯是**常...
